Iais Gcor Study Quiz/Transportation Employees

The correct answer is "Be in good working condition and reliable, Display hours, minutes, and seconds." This answer is the most comprehensive and accurate option because it includes all the necessary requirements for the watch. It specifies that the watch must be in good working condition and reliable, ensuring that it functions properly and provides accurate timekeeping. Additionally, it states that the watch should display hours, minutes, and seconds, which is important for accurate time tracking.

The correct answer is that all answers are correct. This means that in order to recognize and follow signals correctly, employees must always be on the lookout for signals, comply with the intent of the signal, and not act on any signal that they don't understand or that may be intended for other trains or engines. All of these actions are necessary to ensure the safe and efficient operation of trains and to prevent accidents or misunderstandings.

Yellow flags are used to indicate temporary speed restrictions on the track. This is necessary to ensure the safety of trains and workers in areas where maintenance or repair work is being carried out. By signaling temporary speed restrictions with yellow flags, train operators are alerted to reduce their speed and proceed with caution in order to prevent accidents and ensure the smooth flow of traffic on the track.

If a track bulletin form B is not in effect, permission must include speed and distance. This means that when the red flag is lifted and permission is given to proceed, the instructions must specify both the speed at which the train is allowed to travel and the distance for which this speed restriction applies. This ensures that the train operates safely and within the designated limits.

When red flags or red lights are displayed between the rails, the train must come to a stop and cannot continue until the flag or light has been removed by an employee of the class that placed it. This means that only the person responsible for placing the flag or light can remove it, ensuring that the train remains stationary until it is safe to proceed.

If movement is stopped while the trailing end is between the outer opposing absolute signals of a control point or manual interlocking, the movement must not change direction without permission from the control operator. This means that the movement cannot reverse or switch directions without explicit authorization from the control operator. This ensures that the movement is coordinated and controlled to maintain safety and prevent any potential accidents or conflicts with other trains or signals.

The correct answer is "Except in an emergency. In this case, notify the train dispatcher immediately." This means that cars or equipment should not be left on sidings unless there is an emergency situation. In such cases, it is important to inform the train dispatcher immediately.

Both answers are correct because employees handling the switch or derail are responsible for both the position of the switch or derail in use and for not allowing movement to foul an adjacent track until the hand-operated switch is properly lined.

The target on a main track switch will be red if the switch is lined in other than its normal position. This means that if the switch is set to a different position than its default or usual position, the target will be red.

A train may comply with the next signal's indication when its aspect (the visual display of the signal) can be clearly seen and the signal governs the track where movement is occurring or will be made. This means that the train must be able to see the signal and the signal must apply to the track the train is on or planning to move onto. The distance between the train and the signal is not mentioned as a factor in determining compliance with the signal.

Before a dual control switch is operated by hand, permission from the control operator is required. This means that the person operating the switch needs to seek approval from the control operator before proceeding with the manual operation. This ensures that proper communication and coordination are maintained between the control operator and the person operating the switch, ensuring safety and preventing any potential conflicts or accidents.

Engines, cars, or equipment should not be detached and left standing entirely between the opposing interlocking signals that control movement at a railroad crossing at grade. This is important because it can obstruct the view of the signals and create a safety hazard for other vehicles and pedestrians crossing the railroad. By leaving the engines, cars, or equipment in this position, it can prevent the signals from being clearly seen and understood, potentially leading to accidents or other dangerous situations. Therefore, it is true that engines, cars, or equipment must not be detached and left standing entirely between the opposing interlocking signals at a railroad crossing.

When the radio is used instead of hand signals, it is important to provide directions and distance to be traveled. This is because hand signals may not be visible or may not effectively communicate the required information. By providing directions, the person receiving the information can understand the intended path or route to be taken. Additionally, by specifying the distance to be traveled, the person can have a clear understanding of the distance they need to cover in order to reach their destination. This ensures clear communication and helps in avoiding any confusion or misinterpretation of the instructions.

A signal raised and lowered vertically is a signal to proceed. This means that it is safe to continue moving forward and there are no obstacles or hazards ahead.

If a person disappears who is giving the signal to back or shove a train, engine, or car, or if the light being used disappears, employees must stop movement, unless the employee on the leading car controls the air brakes. This is important because without the signal or light, it may not be safe to continue the movement. However, if the employee on the leading car is able to control the air brakes, they can ensure the movement is done safely and can proceed.

Before a crossover movement starts, both switches of a crossover must be operated. This means that the crew member needs to line the first switch of the crossover before the movement begins and then open the other switch when the movement is halfway through. This ensures a smooth and safe transition for the train or vehicle crossing from one track to another. It is a necessary precaution to prevent any accidents or derailments during the crossover movement.

The conductor and engineer must each have a copy of the track warrant issued to the train, and each crew member must read and understand it. This is important for ensuring the safety and coordination of the train's operations. Having a copy of the track warrant allows the conductor and engineer to have the necessary information and instructions for the train's route and any potential hazards or restrictions. Each crew member reading and understanding the track warrant ensures that everyone on board is aware of the instructions and can contribute to the safe operation of the train.

The location of absolute signals controlled by a control operator is referred to as a control point. This is the designated area where the control operator is stationed to manage and control the absolute signals. It serves as a central point from where the control operator can monitor and regulate the signals to ensure smooth and safe traffic flow.

Crossings that intersect at the same level are called "crossings at grade". This term is commonly used in transportation and refers to intersections where two or more roads or railroad tracks cross each other at the same elevation. These crossings can be dangerous as they often require vehicles or pedestrians to cross the path of oncoming traffic. Therefore, it is important to exercise caution and follow traffic signals and signs when approaching crossings at grade.

An electric switch lock is a type of lock that is controlled by electricity and is used to restrict the use of a hand-operated switch or derail. This means that the switch or derail can only be operated when the electric switch lock is unlocked or disengaged. The electric switch lock adds an extra layer of security and control to the operation of the switch or derail, ensuring that it can only be used when authorized.

The correct answer is "Track bulletin, general order, or special instructions." This is because these documents are official written communications that provide specific instructions and information regarding the operation of trains. They are issued by the appropriate authorities and must be followed by train personnel to ensure safe and efficient train operations. Verbal authority from the train dispatcher or trainmaster may also be valid, but the track bulletin, general order, or special instructions carry more weight as they are official written documents. The Federal Register is not directly involved in issuing or modifying rules for train operations.

Employees must be familiar and comply with the requirements of the Federal hours of service laws. These laws regulate the maximum number of hours that employees in certain industries, such as transportation, can work in a given period. It is important for employees to be familiar with these laws to ensure they are not exceeding the allowed hours of work, which can lead to fatigue and safety hazards. By complying with these laws, employees can ensure they are working within the legal limits and promoting safety in their workplace.

The conductor and engineer are responsible for the safety of their train and observance of the rules. The conductor is in charge of managing the train's crew, ensuring that the train operates safely, and enforcing safety protocols. The engineer, on the other hand, is responsible for operating the train and adhering to the rules and regulations of the railway system. Together, they work as a team to ensure the safety of the train and its passengers.

An employee must not act upon a communication and treat it as if it was not sent when they do not understand the radio communication or receive a communication that is incomplete. This is because it is important for the employee to have a clear understanding of the communication before taking any action. Acting upon a communication that is not understood or incomplete can lead to misunderstandings, errors, and potential safety hazards. Therefore, it is crucial for the employee to seek clarification or wait for a complete communication before taking any action.

A general order is a method of communication used to notify individuals of changes or updates in procedures or schedules. In this case, at least 24 hours before a new timetable goes into effect, a general order will be issued to inform relevant parties about the upcoming changes. This ensures that everyone involved is aware of the new timetable and can make necessary adjustments or arrangements accordingly.

The correct answer is "Indicate the rear of the train." This means that a marker of the prescribed type should be displayed on the trailing end of the rear car in order to show or signal that it is the end or rear of the train. This is important for other trains or vehicles to be able to identify and recognize the rear of the train.

An alternate marker is a reflector, red flag, or light fixture. This type of marker is used to indicate a hazard or provide a warning signal. Reflectors are commonly used on roads and vehicles to increase visibility at night or in low-light conditions. Red flags are often used to mark dangerous areas or indicate the presence of an obstacle. Light fixtures, specifically those with a red light, can also serve as alternate markers to indicate a hazard or provide a warning signal.

Before initiating movement on a main track, a crew member must either receive a track warrant or determine from the train dispatcher or yardmaster if any track bulletins are needed. This ensures that the crew member has the necessary authorization and information to safely proceed on the track. The track warrant serves as official permission to occupy and use a specific section of track, while the track bulletins provide important information about any temporary restrictions or conditions on the track. By following this procedure, the crew member can ensure that they have the necessary clearance and are aware of any potential hazards or restrictions before starting their movement.

The maximum speed allowed on movements at restricted speed is 20 mph. This means that when operating at restricted speed, the train or vehicle must not exceed a speed of 20 mph. Restricted speed is a cautionary speed that is typically used in areas where there may be obstructions or hazards on or near the tracks or roadway. By limiting the speed to 20 mph, it allows for increased reaction time and the ability to safely navigate through these potentially dangerous areas.

Employees must inspect passing trains and notify crew members if they detect any dangerous defects. The notification can be given by any available means. This means that employees can use various methods such as hand signals, radio communication, or any other means of communication that is accessible to them. The important thing is to ensure that the crew members on the passing train are informed about the dangerous defect so that appropriate action can be taken to address the issue.

When a train or cut of cars is parted closer than 250 feet from a road crossing, or when the head-end of a train is stopped closer than 250 feet from a road crossing, it is necessary to position an employee on the ground to warn traffic against movements approaching on adjacent tracks. This is important for ensuring the safety of both the employees and the public, as it helps prevent accidents or collisions between vehicles and trains. Therefore, both conditions mentioned in options A and B are correct and require an employee to be positioned on the ground for traffic warning.

The correct answer is the employees handling switches and derails. They are responsible for ensuring that the switches and derails are properly aligned for the intended route. This is an important task to ensure the safe and efficient movement of trains in a railway yard or station. The yardmaster, section foreman, and conductor may have supervisory roles, but the employees directly handling the switches and derails have the primary responsibility for their proper alignment.

If a light is absent or a white light is displayed where a colored or lunar light should be, the most appropriate action is to regard the block or interlocking signal as displaying the most restrictive indication that the signal can give. This means that the absence or white light should be treated as if it is displaying the most severe signal aspect, indicating a need for caution or restricted speed. It is important to follow this protocol to ensure safety and prevent any potential accidents or incidents.

Before entering Form B track bulletin limits, a crew member must contact the person in charge by radio to avoid delay and report the train's location and the track being used. This is important to ensure proper communication and coordination between the crew member and the person in charge, and to ensure that the crew member is aware of any potential delays or issues that may affect their entry into the track bulletin limits. Reporting the train's location and the track being used also helps to maintain safety and prevent any conflicts with other trains or maintenance activities on the track.

Yard limits refer to a specific portion of the main track that is designated by yard limit signs, timetable special instructions, or a track bulletin. This section of the track is where yard operations are conducted, such as switching and classifying cars. It is important for train crews to be aware of yard limits as they may have different rules and restrictions compared to other sections of the track.

The conductor must remind the engineer that the train is approaching an area restricted by a track warrant, radio speed restriction, and track bulletin. This means that the train must follow specific instructions and regulations in this area for safety reasons.

The correct answer is "By any employee operating the controls of a moving engine." This means that employees who are in charge of operating the controls of a moving engine are not allowed to copy track warrants and track bulletins. This is likely a safety measure to ensure that the employee's full attention is on operating the engine and maintaining the safety of the train.

In order to avoid injury or damage when engines are working on both ends of a track, crews switching must have a clear understanding of the movements to be made. This means that the crew members need to know exactly how and where they should move the engines in order to prevent any accidents or collisions. Hand signals or the use of the radio may also be involved in communication, but the most important aspect is the crew's understanding of the specific movements that need to be executed.

The correct answer states that the train or engine must not foul a switch at either end of the limits where an opposing train may use that same switch to clear the main track. This means that the train or engine should not block or obstruct the switch that another train may need to use in order to clear the main track. By not fouling the switch, the train or engine ensures that there is a clear path for the opposing train to safely move off the main track.

A track warrant is in effect until a crew member has reported clear of the limits or until it has been made void. This means that the track warrant remains valid until either the crew member has confirmed that they are no longer within the specified limits or if the warrant is canceled or invalidated for any reason.

The word "void" must be written by a crew member across each copy of the track warrant when the train has been reported clear of the limits or when the track warrant is made void. This ensures that the track warrant is no longer valid and cannot be used for any further train movements. It serves as a clear indication that the track warrant is no longer in effect and helps prevent any confusion or potential accidents on the tracks.

Centralized traffic control (CTC) is a remotely controlled block system that uses block signal indications to authorize train movements. In CTC, the movement of trains is controlled from a central location, where the dispatcher can monitor and control the signals and switches. The block signal indications provide information to the train operators about the status of the track ahead, allowing them to proceed safely. CTC is an advanced system that enhances efficiency and safety in train operations by providing centralized control and real-time monitoring of train movements.

The conductor must inform the engineer of a restriction after the train passes the last station, but at least 2 miles from the restriction. This ensures that the engineer has enough time to prepare for the restriction and adjust the train's speed accordingly. Informing the engineer earlier than 2 miles from the restriction may not provide enough time for the necessary adjustments to be made.

In radio communication, the term "Over" is used to indicate that the transmitting employee has finished speaking and is now expecting a response. It allows the receiving party to know that they can now speak and continue the conversation. "Out" is used to indicate the end of the communication and that no further response is expected. "Come on Back" is not a commonly used phrase in radio communication, and "Over and out" is contradictory as "Over" and "Out" have opposite meanings. Therefore, the correct answer is "Over".

In order to occupy a main track, a train must have authority. This means that the train has been given permission to be on the track and proceed with its journey. This authority could be given in different ways, such as through CTC (Centralized Traffic Control) or track warrant authority in CTC. The other options, like authority in non-signaled territory only or authority in CTC only, are not comprehensive enough to cover all scenarios where a train may need to occupy a main track.

In non-signaled Yard Limits, trains must move at restricted speed. This means that trains must be able to stop within half the range of vision, must be able to stop before encountering an obstruction, and must always be prepared to stop. This is a safety measure to ensure that trains can safely navigate through the yard limits without the need for signals.

When a train stops to let another train meet or pass it, trainmen on the head end must inspect the passing train from the ground. This is because it is the safest and most practical position to visually inspect the passing train for any issues or abnormalities. Inspecting from the engine cab or the railing of the engine may not provide a clear and comprehensive view of the passing train. Additionally, inspecting from any place except on the ground may pose safety risks and hinder the ability to thoroughly assess the passing train.

The correct answer is "Both A and B are correct". This means that both statements A and B are true. Statement A states that an employee must be on the ground at the crossing to provide a warning until the crossing is occupied. Statement B states that any movement over the crossing should only be made on the employee's signal. Therefore, both statements emphasize the importance of having an employee present at the crossing to ensure safety and proper traffic control.

When a crossing is equipped with gates that are fully lowered, it provides a physical barrier that prevents vehicles and pedestrians from crossing the tracks when a train is approaching. This ensures the safety of individuals and eliminates the need for additional warning signs or devices. Similarly, if the crossing has flashing lights or passive warning devices, it indicates that there is a train approaching and warns the individuals to stop and wait until the train passes. Hence, both options A and B are correct as they provide adequate safety measures at the crossing.

Releasing the hand brakes before the air brake system is fully charged can result in an uncontrolled movement of the train or cars. The hand brakes are an additional safety measure that should only be released once the air brake system is fully charged and able to provide sufficient braking force to control the movement of the train or cars.

Blocking the wheels is the correct answer because if hand brakes are not sufficient to prevent movement, blocking the wheels provides an additional level of safety. By placing a physical obstruction in front of or behind the wheels, the movement of the cars can be effectively stopped. This ensures that the cars remain stationary and reduces the risk of accidents or unintended movement.

Within TWC territory, the use of the main track will be authorized by a track warrant.

Track warrant control (TWC) is a method used to authorize train movements or protect men or machines on a main track within specified limits in a territory designated by the timetable. This means that TWC allows for the control and authorization of train movements by issuing track warrants. It ensures that trains can safely operate within a specific area and prevents any conflicts or accidents from occurring. Centralized traffic control (CTC) and timetable control are other methods of train control, but in this case, TWC is the correct answer as it specifically refers to authorizing train movements and protecting men or machines on a main track within specified limits.

Employees subject to call must provide their contact information and notify those who are required to call them if they will be absent from their designated calling place. This ensures that communication can be maintained and any necessary instructions or updates can be relayed effectively. By doing so, employees can ensure that they are reachable and can fulfill their responsibilities promptly and efficiently.

A student engineer or other qualified employee can operate the engine, but only under the close supervision of the engineer. This means that they must be closely monitored and guided by the engineer during the operation of the engine.

The correct answer is "The speed specified must not be exceeded until the rear of the train clears the restricted area." This means that even if the train has passed the restricted area, it is still required to maintain the specified speed until the entire train, including the rear, has cleared the area. This ensures the safety of the train and prevents any potential accidents or collisions.

When a train or engine is approaching or passing on a main track, the employee must not be nearer than 20 feet to any track switch. This distance is necessary to ensure the safety of the employee and prevent any potential accidents or injuries. Being too close to a track switch can put the employee at risk of being struck by the train or engine or getting caught in the switching movements. Therefore, it is important for the employee to maintain a safe distance of 20 feet from the track switch in such situations.

A track bulletin is a communication tool used in the railroad industry to issue, change, or cancel various instructions related to track operations. These instructions can include rules, general orders, and special instructions. Therefore, all the given options - rules, general orders, and special instructions - can be issued, changed, or canceled using a track bulletin.

The correct answer is "Restricted speed." When the foreman gives permission for the train to enter the Form B area without specifying a speed, the train must operate at restricted speed. Restricted speed means that the train must be able to stop within half the range of vision, must be able to stop short of any obstruction on the track, and must be prepared to stop at any time. This allows the train to proceed cautiously and safely through the area.

Yard limits and yard have different meanings and applications. Yard limits specifically apply to the main track, indicating the section of the track where certain rules and restrictions are in place. On the other hand, a yard refers to an area other than the main tracks and sidings, typically used for storing, classifying, and assembling trains. Therefore, the correct answer states that yard limits apply to the main track, while a yard is located in other areas.

The correct answer is "Stop because of men or equipment." The yellow-red flags are used as a signal to the train operator that there are men or equipment on or near the tracks. This indicates that the train should come to a stop to ensure the safety of the workers or equipment.

A green flag indicates the end of a restricted area. This means that any restrictions or limitations that were in place for the train, such as reduced speed or cautionary measures, are no longer applicable once the green flag is passed. It signifies that the train can resume normal speed and continue its journey without any restrictions.

A train can receive authority to enter interlockings either through a signal indication from a controlled signal that indicates proceed or through verbal authority from the control operator. This means that the train can proceed into the interlocking if it receives a signal indicating that it is safe to do so, or if the control operator verbally gives permission for the train to enter. Both of these methods ensure that the train has the necessary authorization to enter the interlocking.

When a main track switch is attended by a crew member or switch tender, it is an exception to the rule that the normal position of the switch is for main track movement. In this case, the switch can be left open, deviating from its usual position, as long as it is being supervised by a crew member or switch tender. This exception allows for flexibility in the operation of the switch when there is direct oversight.

An absolute signal refers to a block or interlocking signal that does not have a number plate. This means that it does not display any specific information or indication, but rather serves as a general signal without any additional instructions. It is important to differentiate absolute signals from other types of signals that may display a red aspect or have a number plate, as they have different meanings and implications for train operations.

A controlled siding refers to a siding within CTC or interlocking limits where a signal indication is required to authorize the use of the siding. This means that train operators must receive a specific signal indication before using the siding, ensuring the safe and controlled movement of trains on the tracks.

A timetable is a publication that provides instructions on trains, engine, or equipment movement. It outlines the schedule and routes for trains, allowing passengers and railway staff to plan their journeys and coordinate movements. Unlike a rule book or train and equipment manual, a timetable focuses on the timing and sequencing of train movements rather than the specific rules and technical details of the equipment or operations. Therefore, a timetable is the correct answer in this context.

In this scenario, the correct answer is that the employee in charge gives verbal permission. This means that when a train approaches a red flag or red light, it must stop until the employee in charge explicitly gives permission to proceed. This ensures that there is proper communication and coordination between the train and the person responsible for overseeing the operations. The train should not proceed without receiving this verbal permission from the employee in charge.

Before moving engines or cars through gates, doorways, or similar openings, it is important to ensure that the gates, doorways, or openings are completely open and secure. This means that they should be fully open to allow for safe passage of the vehicles, and they should also be secure to prevent any accidents or damage during the movement. It is crucial to check both aspects to ensure a smooth and safe transition of the engines or cars through the openings.

After lining the switch to let a train enter or leave the main track, the employee must go to the opposite side of the main track until the movement is complete. This is necessary to ensure the safety of the employee and to prevent any potential accidents or collisions with the moving train. By going to the opposite side of the main track, the employee can maintain a safe distance from the train and avoid any potential hazards. Once the movement is complete, the employee can then proceed with their duties or return to their original position.

An automatic block signal system (ABS) is a system where block signals are activated by a train or certain conditions that affect the block. In this system, consecutive blocks are governed by block signals, ensuring safe and efficient train operations. Centralized traffic control (CTC) is a different system where a centralized control center manages train movements. Track warrant control (TWC) is a system where train movements are authorized by track warrants. Absolute block signal system (ABSS) is a term used to describe a system where each block is protected by a fixed signal and trains must receive permission to enter the block. However, none of these systems fully match the given description except for the automatic block signal system (ABS).

A crossover refers to a combination of two switches that connect two adjacent tracks. This allows trains to move from one track to another, typically in opposite directions. By using the crossover, trains can change tracks without having to reverse or make a large detour. This helps to improve efficiency and flexibility in the railway system.

Before beginning each day's work or trip, trainmen, enginemen, and others whose duties require must review General Orders, Circulars, instructions, and notices that apply to the territory they will work on. This ensures that they are aware of any updates, changes, or specific instructions for their assigned territory. By reviewing these documents, they can stay informed and ensure the safety and efficiency of their work. There is no mention of logging the highest number on their time slips or in the log book, so those options can be eliminated. Therefore, the correct answer is to review the relevant documents for their territory.

The engineer is responsible for the safe and efficient operation of the engine. Therefore, it is logical to conclude that the crew members, who work closely with the engineer and are involved in the operation of the engine, must obey the engineer's instructions concerning its operation.

Under any of the listed conditions, a movement must not foul a crossing equipped with automatic warning devices until the device has been operating long enough to provide warning and the crossing gates, if equipped, are fully lowered. This means that if a movement has been delayed or stopped within 3000 feet of the crossing, or if it is closely following another movement, or if it is on a track other than the main track or siding, or if it enters a main track or siding within 3000 feet of the crossing, it must wait until the warning devices are fully operational and the gates are lowered before crossing the tracks.

The recommended speed for coupling cars or engines is 4 mph. This speed ensures that the cars or engines are properly secured and can be coupled and moved safely. Coupling at a higher speed may increase the risk of accidents or damage to the equipment. Coupling at a lower speed may not provide enough force to properly secure the cars or engines together. Therefore, it is important to follow the recommended speed of 4 mph for safe and effective coupling.

When a block is occupied or a switch protected by a signal is changed from its normal position, if the signal fails to display its most restrictive indication, it should be regarded as displaying "Stop". This means that the train should come to a complete stop and not proceed further until further instructions are received.

Trains must move according to signal indication, unless they are in joint track and time, in which case restricted speed is required. This means that trains should follow the signals and adjust their speed accordingly. However, if they are in joint track and time, they must operate at a restricted speed. This ensures safe and efficient movement of trains on the track.

A siding is a track that is connected to the main track and is used for meeting or passing trains. The location of sidings is shown in the timetable.

The given answer states that all answers are correct. This means that safety is indeed the most important element in performing duties, it should never be compromised, and rules compliance is also crucial. All of these statements align with the concept of safety and emphasize its significance in any task or activity. Therefore, the answer is valid and encompasses all the important aspects of safety.

Employees must make sure their watch does not vary from the correct time by more than 30 seconds. This means that their watch should not be more than 30 seconds ahead or behind the correct time. It is important for employees to have accurate timekeeping in order to ensure punctuality and coordination with other colleagues or activities. A variation of more than 30 seconds could lead to disruptions in schedules and potential inefficiencies in the workplace.

If the headlight on the train fails, the ditch lights must be on, when so equipped. Ditch lights are additional lights on the front of the train that are used to increase visibility and alert other vehicles and pedestrians of the train's presence. By having the ditch lights on when the headlight fails, the train can still maintain visibility and ensure safety while continuing to move.

The correct answer states that the control operator authorizes the train to enter tracks between block signals by stating "(Train)at(location) has authority to enter (track) and proceed (direction)". This means that the control operator explicitly grants authority to the train by providing specific information about the train's location, the track it is authorized to enter, and the direction it should proceed in. This ensures clear communication and allows the train to safely enter the track.

Employees are required to keep and comply with track bulletins on all trips during their tour of duty when track bulletins were received. This means that employees must adhere to the instructions and guidelines provided in the track bulletins while they are on duty and during their trips. Compliance with track bulletins is necessary to ensure safety and proper functioning of operations.

The train dispatcher will not transmit a restricting warrant or track bulletin to a train near a point where the restriction applies until the engineer or conductor confirms that they can comply with it. This is because it is important to ensure that the train can safely adhere to the restriction before transmitting the warrant or bulletin. By waiting for confirmation from the engineer or conductor, the dispatcher can ensure that the train is able to comply with the restriction and avoid any potential safety hazards.

When a radio transmission is complete and no response is expected, the transmitting employee must say "Out, preceded by required identification". This indicates that the communication is finished and the employee is signing off. By including the required identification, the employee ensures that their message is clear and can be properly attributed to them.

Both A and B are correct because according to the given information, it is permissible to give the name, position, aspect, or indication displayed by a fixed signal on the radio. This permission applies when the communication is between members of the same crew and when the information is needed to warn of an emergency. Therefore, both scenarios mentioned in options A and B are valid for giving such information on the radio.

A hand or light signal swung at a right angle to the track is a signal to stop. This signal indicates to the train operator or driver that they should bring the train to a halt. It is important for the train operator to be aware of and respond to this signal promptly to ensure safety and avoid any potential accidents or collisions.

Flags will be placed to the right of the track as viewed by an approaching train, unless there is a specific instruction in a track bulletin, track warrant, special instructions, or general order stating otherwise. This means that the default placement of flags is on the right side of the track, but it can be changed if there is a specific directive.

When an emergency exists or there are persons or livestock on the track, the whistle signal used is a succession of short sounds. This signal alerts crews on other trains to stop and wait until it is safe to proceed. The short sounds are used to quickly grab attention and convey the urgency of the situation.

In railway operations, reverse movements refer to trains moving in the opposite direction. These movements are typically made at restricted speed, which means the train must be able to stop within half the range of vision. This allows the train operator to have better control and awareness of the surroundings while moving in reverse. Therefore, the correct answer is restricted speed.
