Ns 100 ? OP-rules

The correct answer is "A speed not exceeding 30 MPH." This answer describes medium speed as a speed that does not go beyond 30 miles per hour. It suggests that medium speed is slower than high speed but faster than slower speeds such as 20 or 15 miles per hour.

The Conductor and Engineer of the affected passenger train must be governed by all of the given options. They should not load or unload passengers, contact the Train Dispatcher/Control Operator, and provide protection against movement on the track(s) between the passenger train and platform. This ensures safety and proper coordination in such a situation.

A job briefing is required at the beginning of each job to ensure that all workers are aware of the tasks, safety protocols, and any specific instructions related to the job. It is also necessary when the work changes to update the workers on the new tasks or procedures. Additionally, if the work becomes confusing or new tasks are started, a job briefing is necessary to clarify any confusion and provide guidance. Lastly, if a rule violation is observed, a job briefing may be required to remind the workers of the rules and ensure compliance. Therefore, all of the given answers are correct.

A Track Authority Form or any similar form cannot be filled out in advance of receiving information from the Train Dispatcher/Control Operator. This is because the information provided by the Train Dispatcher/Control Operator is crucial for accurately filling out the form. Any changes or corrections to the information received must be made before repeating the form. Therefore, filling out the form in advance without the necessary information would not be permissible.

The engine bell must be rung in multiple situations. It should be rung when an engine is about to move, to alert anyone nearby of its impending motion. It should also be rung when approaching and passing public crossings at grade, to warn pedestrians and vehicles of the approaching train. Additionally, the bell should be rung when passing through tunnels, as the sound can help to alert anyone inside the tunnel of the approaching train. Therefore, all of the given answers are correct.

Limited speed refers to a maximum speed limit that should not be exceeded. In the case of this question, the correct answer states that limited speed is defined as not exceeding 45 MPH for passenger trains and 40 MPH for freight trains. This means that these types of trains should not go faster than these specified speeds.

The employee directing the move must specify the direction of the move and the distance seen to be clear, as established in a job briefing. They should also specify the distance of the movement in 50-foot car lengths. Additionally, when the move comes within five car lengths of the stop or coupling, they should call out the distances in car lengths. All of these actions are correct and necessary for safely directing a movement by radio.

The correct answer is that all of these answers are correct. This means that the employee at the controls of a locomotive receiving instruction from an employee directing the move by radio must stop in one-half the distance last received unless additional instructions are received when given the distance to move in 50-foot car lengths. They must also stop the move immediately after moving one car length during the countdown unless receiving additional signals from the person directing the move. If the instructions are not understood or continuous radio contact is not maintained, they must stop the movement immediately.

The correct answer is "3-Step Protection." This refers to a safety protocol on the Norfolk Southern railway where before fouling equipment, employees must verbally request, acknowledge, and maintain the protection until they are notified by the employee requesting it that the protection is no longer required. This ensures that proper safety measures are taken to prevent accidents and injuries.

When a Conductor and/or Engineer is relieved before completion of a trip and all Authority Forms and instructions held by them cannot be personally delivered to the relieving crew, they must be left in an envelope at a location designated by the Train Dispatcher/Control Operator. The envelope should clearly indicate the correct designation of the train, date, location, and Conductor's signature. This ensures that the documents are securely stored and can be easily located by the appropriate personnel.

When an Authority is in effect and it is necessary to change the limits or instructions, a new Authority must be issued and include the words "Authority No. ____ is void." This means that the previous Authority is no longer valid and the train must operate based on the new Authority. This ensures that there is clear communication and understanding between the Train Dispatcher/Control Operator and the train regarding the changes in limits or instructions.

The correct answer is "A speed not exceeding 15 MPH." This is because slow speed is defined as a speed that does not exceed 15 miles per hour.

After the "OK" time is recorded on the form, the Authority to occupy the track is in effect. This means that the train or individual is permitted to occupy and use the track after the specified "OK" time has been recorded. This ensures that there is a clear and designated time for the authority to take effect, providing safety and coordination in track usage.

All crew members, including the Conductor and Engineer, must read and understand the mandatory directive before it is acted upon. This ensures that everyone on the crew is aware of the directive and can follow it accordingly. It is important for all crew members to be familiar with the directive to ensure the safety and efficiency of the operation.

If a Conditional Stop sign is not found at the designated location or time, the train must not proceed until the Train Dispatcher/Control Operator is notified immediately. Additionally, the train must not proceed until the Engineer is notified by radio or in person by the employee in charge of the working limits that the track is clear. This ensures that proper communication and coordination are maintained to ensure the safety of the train and its passengers.

When approaching public highway-rail crossings, the engine horn must be sounded at least 15 seconds but not more than 20 seconds before occupying the crossing. This ensures that pedestrians and motorists are alerted to the presence of the train and can safely clear the tracks. Beginning the signal at or about the whistle post, but not more than one-fourth 1/4 mile from the public crossing, ensures that the horn is sounded with enough time for people to react, but not too far in advance that it may cause confusion or unnecessary noise pollution.

The given answer is correct because it states that all of the options mentioned in the previous statements are correct. The Train Dispatcher/Control Operator should state the total number of boxes marked and identify the individual box numbers. Additionally, all the words of each item designated, including preprinted ones, should be pronounced. Multiple-digit numbers should be pronounced and repeated digit by digit, while one-digit numbers and directions should be pronounced and spelled. Station names and other words should be pronounced and spelled when necessary for clarity. Therefore, all of these answers are correct.

When a signal is functioning erratically, the train must regard it as the most restrictive indication given by that signal. This means that the train should assume that the signal is displaying the most severe indication, such as a Stop signal, in order to ensure safety. This approach is necessary because the erratic behavior of the signal may lead to confusion or incorrect indications, so it is important for the train to prioritize safety by assuming the most restrictive indication.

If a train or engine passes a signal displaying Stop without authority, all of the mentioned actions must be taken. The train must be stopped immediately to avoid any potential accidents. The crew must also warn any other movement that could be approaching on conflicting routes by radio. If communication is not possible, they must provide protection against any approaching movement. Additionally, they must notify the Train Dispatcher/Control Operator or the proper authority to report the incident and ensure proper follow-up actions are taken.

After recording all the information and instructions from the Authority Form, the receiving employee must repeat it to the Train Dispatcher/Control Operator. They must also state the total number of boxes marked on the Authority Form and identify the individual box numbers. Additionally, if the Authority Form authorizes a train meet, the receiving employee must state "this Authority requires a meet with Locomotive (number), (direction) at (location)".

When the limits of an Authority have been reported clear, or limits or instructions have been changed, crew members must write the word "VOID" legibly across each copy of the Authority Form.

A Home Signal is a fixed signal that has the capability to display a STOP indication. It is responsible for governing the entrance to a route, block, interlocking, or controlled point. This signal plays a crucial role in controlling the movement of trains and engines by indicating whether they are allowed to proceed or must come to a stop.

The tag and/or securing device may be removed by direction of the person in charge of the workers being protected. This person is responsible for ensuring the safety of the workers and has the authority to determine when it is safe to remove the tag and/or securing device.

A signaled siding is an auxiliary track that is equipped with signals, allowing trains to safely meet or pass each other. It is shown as a siding in the Timetable and is governed by Rule 261, which controls all train and engine movements on the siding. Therefore, the correct answer is "Signaled siding."

Employees must wait until cars or engines are separated by at least 50 feet before going between them to adjust a coupler or knuckle. This distance ensures their safety and prevents any potential accidents or injuries that could occur if they were to be caught between the moving parts of the equipment.

Train and engine service employees may manually raise grade crossing gate arms that are in a horizontal position to permit the passage of emergency response vehicles when it is known by the employee(s) that the vehicle can cross safely. This means that if there is an emergency situation and it is determined that the vehicle needs to cross the tracks immediately, the gate arms can be manually raised to allow for the safe passage of the emergency response vehicle.

When all headlight bulbs, including auxiliary lights, fail en route, the train must be governed by notifying the Train Dispatcher/Control Operator as soon as practical, ringing the bell continuously, and sounding the horn frequently. The train should also approach all public crossings at grade prepared to stop and proceed over the crossing not exceeding 20 MPH (head end only). Additionally, the train should reduce speed when required by prevailing conditions, not exceeding 50 MPH at night. Therefore, all of the given answers are correct in this situation.

Each time a crewmember changes the position of a hand-operated main track switch in non-signaled territory, they must communicate with the Engineer while physically at the switch stating the switch name and location, as well as the position of the switch (Normal or Reverse). The Engineer must acknowledge this information before making any movement. Therefore, all of the given answers are correct.

After making the initial radio announcement, the crew's responsibility is to promptly report the emergency brake application to the Train Dispatcher/Control Operator, providing train identification, direction, milepost location, and track designation. They should also repeat the emergency warning as necessary until protection is provided by the Train Dispatcher/Control Operator or until it is known that adjacent tracks are not obstructed. Additionally, they must inspect the train before it is moved.

If a movement is authorized to "PROCEED" between designated points, it is allowed to foul the first siding switch at the first named point and the last siding switch at the second named point. However, movements must not foul a switch at either end of the limits that an opposing train may use to clear the main track. This is to ensure the safety of opposing trains and prevent any potential collisions or accidents.

The requirements for inspecting passing trains include observing both sides of passing trains when multiple employees can safely position themselves in advance, notifying other crew members on the train when employees are in position to inspect their passing train, and observing passing trains for defects such as sticking brakes, hot journal, broken or loose wheel, brake rigging down, load shifted, or other trouble, and exchanging information by radio about the condition of the trains.

When a train is "OS'ed" (reported as having passed a point) by a crew member, the Train Dispatcher/Control Operator will consider the main track "clear" up to and including that point. This means that other trains can proceed on the main track without any obstruction or risk of collision up to the reported point. The authority given to the train remains valid, but the train authorized by the authority cannot make a reverse movement past the point at which it was last reported to have passed by a crew member.

In the event of an emergency brake application on a moving train, a crew member must immediately announce the situation over the radio. This announcement should include the train's identification, the direction of the emergency brake application, the milepost location, and the track designation if applicable. This communication is crucial for informing other crew members and authorities about the emergency, allowing them to take appropriate action.

The sign described in the question is a Conditional Stop Sign. It is located at the beginning of the working limits of a Form Y.

Operations Bulletins are issued on or after January 1 of each year and expire at 11:59 PM on December 31. This means that they are valid for the entire year and must be followed until the end of December 31.

If a Conditional Stop Sign is found at a location or time not designated by Form Y, the correct procedure is to notify the Train Dispatcher/Control Operator immediately. The train should not proceed until the Engineer has been notified by radio or in person by the employee in charge of the working limits that the track is clear, or until the Conditional Stop Sign is removed by the proper authority. This ensures that the train does not proceed without proper clearance or authorization, maintaining safety protocols.

When governed by Track Authority Rules, the movement must be made ONLY in the direction specified. This means that the movement is not allowed to be made in the reverse direction or in any other direction. The authorized movement can be made at the maximum authorized speed between the designated points.

A crew member in the controlling locomotive must communicate the designated speed and milepost location of each slow order at least two miles before reaching it. This is important for ensuring that the train operates at the appropriate speed and is aware of the location of the slow order. By communicating this information in advance, the crew can effectively prepare for any necessary adjustments or precautions required for the slow order.

When an improper signal indication is observed, the train or engine must be governed by stopping as soon as possible without endangering the movement. They must also warn any other movement that could be approaching, report the occurrence, and not proceed until authorized by the Train Dispatcher/Control Operator. This ensures the safety of all movements on the tracks and allows for proper communication and authorization before continuing.

A Mandatory Directive refers to any movement authority or speed restriction that affects the movement of a train, engine, On-Track equipment, single or in combination with other equipment. It can also include any form used to authorize the use of controlled track. This means that a Mandatory Directive is a specific instruction that must be followed to ensure safe and efficient operations on the railway. It is a crucial element in maintaining the integrity and reliability of the railway system.

When a train receives information that another train is in emergency on an adjacent track, it must operate at Restricted Speed while passing the train until it is confirmed that the track is clear. This means that the train must proceed at a speed that allows it to stop within half the range of vision, be able to stop before encountering any obstruction, and be prepared to stop within half the range of vision of any train or obstruction on the track. This precaution is taken to ensure the safety of all trains involved and to prevent any potential accidents or collisions.

After the equipment has passed the clearance point, it is safe to line the locomotive or car away from the track. The clearance point refers to the point where there is enough space for the equipment to safely maneuver and be directed onto a different track. Lining the equipment away from the track before it passes the clearance point could result in a collision or derailment. Therefore, it is important to wait until the equipment has passed the clearance point before making any changes to its direction.

Trains or engines may be authorized exclusive track occupancy, which means they have permission to operate on a specific track. This authorization allows them to operate in both directions. The authority for this must be recorded on a prescribed form, which includes identification, track designation, time limits, and limits to be used. Therefore, all of the given answers are correct as they explain different aspects of how trains or engines may be authorized to operate in both directions.

The correct answer is "Succession of short blasts". This signal is used as an alarm for employees, roadway workers, or other persons on or near the track. It consists of a series of short blasts, which is an effective way to quickly grab attention and alert individuals to potential danger or an emergency situation.

All of these answers are correct. A train or engine may pass a Controlled or ABS Stop signal after receiving authority to proceed from the Train Dispatcher/Control Operator and instructions received have been repeated. It may also pass the signal after the train has stopped in view of the signal. Additionally, it may pass the signal after a crew member has been fully informed of the situation and knows the move is protected.

When the Conductor is not on the controlling unit to receive the copy of an Authority, the copying employee must inform the Train Dispatcher/Control Operator that the Authority has been read to and acknowledged by the Conductor before the "OK" time is given. This ensures that the necessary communication and acknowledgement between the Conductor and the Train Dispatcher/Control Operator are established before proceeding with the Authority.

When the automatic crossing warning devices at a highway-rail grade crossing have an activation failure and there is no flagger or police officer present, trains must stop before entering the crossing. A crew member must then dismount from the train and flag highway traffic to a stop. This is necessary to ensure the safety of both the train and the highway traffic, as there are no functioning warning devices to alert drivers of an approaching train. By having a crew member flag traffic, it helps prevent any accidents or collisions at the crossing.

Rule 261 indicates that the use of a track signaled in both directions will be authorized by signal indications that authorize trains and engines to operate in either direction on the same track and ABS rules apply.

Rule 271 indicates that the use of a track signaled in both directions will be authorized by Track Authority rules that authorize train and engine movements and ABS rules apply. This means that when a track is signaled in both directions, train and engine movements will be permitted according to the Track Authority rules, while also following the ABS (Automatic Block Signal) rules. This ensures safe and coordinated movement of trains on the track.

When a train or engine encounters a Restricting or Stop signal, it must immediately stop as soon as possible without endangering the movement. The occurrence must be promptly reported to the Train Dispatcher/Control Operator. The train or engine should not proceed until authorized by the Train Dispatcher/Control Operator, and when authorized, it should proceed at Restricted Speed. This ensures safety and compliance with the signal indications, while also maintaining communication with the control center.
