NORAC - 10th Edition - Definitions

A marker is a reflector, flag, or highly visible marking device that is affixed to the rear of a train. Its purpose is to indicate that the train is complete. This helps other railway personnel and operators to easily identify that the entire train has passed and there are no more cars or wagons remaining. The marker is usually in the red-orange-amber range, making it highly visible and easily distinguishable from a distance.

The correct answer is "Scheduled Train". In the NORAC - 10th Edition Definitions, a train designated by Timetable Schedule is referred to as a "Scheduled Train". This means that the train is planned and scheduled according to a predetermined timetable. The other options, such as Extra Train, Track Car, and Camp Car, do not fit the given definition and are therefore incorrect.

A dual control switch is a type of power-operated switch that can also be operated manually by hand. This means that it can be controlled both electronically and manually, providing flexibility in how it is operated.

A station is a place designated in the Timetable by name. This means that in the context of the NORAC - 10th Edition – Definitions, a station refers to a specific location that is identified by a name in the timetable. It could be a train station, bus station, or any other type of transportation station. This definition excludes options like junction, switch, and street, as they do not fit the criteria of being designated in the timetable by name.

The correct answer is "Yard". In the context of NORAC - 10th Edition Definitions, a yard refers to a system of tracks used for the making up of trains. This means that a yard is a designated area where trains are assembled or disassembled, and it typically consists of multiple tracks and switches.

An absolute block refers to a block on a railway track that should not be occupied by more than one train at a time. This ensures that there is no possibility of collisions or accidents due to multiple trains occupying the same block. The concept of absolute block is crucial for maintaining safety and preventing any potential conflicts between trains on the track.

An extra train refers to a train that is not designated by a Timetable schedule. This means that it is not part of the regular scheduled trains and is instead added to accommodate additional passengers or freight. The term "extra train" is used to distinguish it from scheduled trains that operate according to a predetermined timetable.

A schedule is a part of the timetable that provides specific information about the direction, number, frequency, and times for the movement of designated trains. It is a detailed plan that outlines the specific arrangements for train movements. A schedule helps ensure that trains operate efficiently and safely by providing clear instructions on when and where trains should be at any given time. It is an essential document for railway operations and plays a crucial role in maintaining a smooth and organized train service.

The correct answer is "The maximum authorized speed." This means that the speeds mentioned (45 MPH, 60 MPH, 80 MPH) are the highest speeds that are allowed or authorized.

The correct answer is "Current of Traffic". In the context of NORAC - 10th Edition definitions, "Current of Traffic" refers to the assigned direction of moment as specified in the Timetable. This term is used to indicate the direction in which trains are expected to move on a particular track or section. It helps to ensure the safe and efficient movement of trains by establishing a consistent flow of traffic.

The correct answer is "Foul Point". In railway terminology, the foul point refers to the point on a track where equipment or objects will interfere or obstruct an adjacent track. This means that if any equipment or object goes beyond the foul point, it will potentially cause a collision or obstruction on the adjacent track. It is important for railway operators to be aware of the foul point to ensure the safe movement of trains and equipment.

An automatic block signal system (ABS) is a type of block signal system that governs the use of each block. It utilizes automatic block signals, cab signals, or both to control the movement of trains. This means that trains can only enter a block when they receive a signal indicating that it is clear and safe to do so. The ABS system helps to ensure the safe and efficient operation of trains by providing clear indications and instructions to train operators.

The correct answer is "Division". In the context of a railroad system, a division refers to a specific portion of the system that is assigned to the supervision of a Superintendent. This means that the Superintendent is responsible for overseeing the operations and management of that particular section of the railroad. The other options, such as Station, Yard, and Line, do not specifically refer to a portion of the railroad system assigned to a Superintendent's supervision.

The term "signal indication" refers to the required action conveyed by the aspect of a signal. In other words, it is the information or instruction provided by a signal that tells the recipient what action to take. This could include instructions such as stopping, proceeding with caution, or changing direction. The term "signal indication" is used to describe the specific action that is conveyed by a signal's aspect.

The correct answer is 45 mph for passenger trains and 40 mph for freight trains. The term "limited speed" refers to the maximum speed allowed for trains. In this case, passenger trains are not allowed to exceed 45 mph, while freight trains are not allowed to exceed 40 mph. These speeds are set to ensure safe and efficient operation of the trains.

In the NORAC 10th Edition, the definition of "SLOW SPEED" is provided. According to the definition, "SLOW SPEED" refers to a speed that does not exceed 15 MPH. This means that when traveling at "SLOW SPEED," the maximum speed allowed is 15 miles per hour.

The correct answer is Cab Signal. A cab signal is a signal located in the engine control compartment that is used in conjunction with interlocking signals to indicate track occupancy or condition. It is often used in place of or in addition to block signals.

A distant signal is a fixed signal used to govern the approach of a train to a home signal. It is located at a distance from the home signal and provides advance warning to the train operator about the status of the home signal. The distant signal allows the train operator to adjust the train's speed and prepare for any upcoming changes in signal indications. It helps in maintaining safe distances between trains and preventing collisions.

The correct answer is Main Track. In the context of NORAC - 10th Edition Definitions, a main track refers to a track that is designated by the timetable for authorized train movements. These movements can be authorized by ABS (Automatic Block Signal), DCS (Dispatcher Control System), or interlocking rules.

The term "reverse movement" refers to a movement that goes in the opposite direction of the previously authorized direction. It implies a change in direction or a movement that goes back or opposite to the initial direction. This term is often used in the context of traffic or transportation to describe a change in the flow of vehicles or a movement that goes against the established traffic pattern.

The correct answer is "Train" because a train is composed of an engine and one or more cars. It can include both passenger and freight cars. The other options listed, such as engine, track car, and camp car, are all components or types of cars that can be part of a train. Therefore, a train can consist of an engine with or without cars.

A controlled point is a station designated in the Timetable where signals are remotely controlled from the control station. This means that the signals at the controlled point are operated and controlled by personnel at a central control station rather than being manually operated at the station itself. This allows for more efficient and centralized control of train movements and signal operations.

The correct answer is "Not exceeding 30 MPH" because in the NORAC 10th Edition Definitions, "Medium Speed" is defined as not exceeding 30 MPH.

A Division Notice is a publication issued periodically by the designated officer that contains instructions or information that do not affect the movement of trains. This means that it provides general information or instructions that are not directly related to the operation or scheduling of train movements. It is different from a General Order or Bulletin Order, which may contain instructions that directly impact train movements.

An interlocking is a system of signals and signal appliances that are interconnected in such a way that their movements must occur in a specific sequence. This ensures that signals cannot be displayed simultaneously on conflicting routes. In other words, it is a mechanism that controls the movements of trains and prevents conflicting movements from occurring.

Return Movement refers to the movement of an uncoupled engine or leading portion of a train that is directed back towards the remaining stationary portion of the same train. This means that the engine or leading portion of the train is moving in the opposite direction to where it was originally going, in order to rejoin the rest of the train.

The correct answer is "Rules-in-Effect". In the context of NORAC - 10th Edition, "Rules-in-Effect" refers to the specific operating rules or group of operating rules that govern the use of tracks. These rules are designated by the Timetable, which means they are the current and applicable rules that must be followed by train operators. The other options listed (Special Instruction, General Order, and Division Notice) are also types of operating rules, but in this case, "Rules-in-Effect" is the most appropriate answer as it specifically refers to the governing rules designated by the Timetable.

An automatic block signal is a type of block signal that is activated either by a track circuit or in conjunction with interlocking or controlled point circuits. This means that the signal is automatically activated based on the presence of trains on the track or the status of other signaling systems. It helps to ensure safe and efficient train operations by providing clear indications to train operators about the status of the track ahead.

Interlocking signals refer to the fixed signals of an interlocking system. An interlocking system is a safety mechanism used in railroads to prevent conflicting movements and ensure safe operations. The interlocking signals are strategically placed at various points along the tracks to indicate to train operators whether it is safe to proceed or if there are any restrictions or hazards ahead. These signals are an integral part of the interlocking system and play a crucial role in maintaining the safety and efficiency of train operations.

A Bulletin Order is a publication that is used to inform employees about changes to rules, procedures, or other instructions that impact the movement of trains. It is issued periodically by the designated officer.

Fouling a track refers to the situation where an individual, tools, or equipment is within four feet of the nearest rail and could be struck by a moving train or on-track equipment. This is a safety concern as it poses a risk of accidents or damage to the individual or equipment.

The correct answer is "Interlocking Limits". Interlocking limits refer to the track between the opposing home signals of an interlocking. This means that it is the section of track that is controlled and monitored by the interlocking system, ensuring safe and efficient movement of trains.

A blocking device refers to a lever, plug, ring, or any other control mechanism that limits or restricts the functioning of a switch or signal. It is used to prevent accidental or unauthorized operation of the switch or signal, ensuring safety and control in various systems or equipment.

A bolt-lock switch is a hand-operated switch that has a pipe connected locking device. This locking device is designed to shunt the signal system before the switch points are operated. This means that the switch can be locked in a certain position to prevent any signals from being sent or received until the switch points are moved. This ensures safety and prevents any accidental signaling or movement of trains before the switch is properly set.

A control station is the location where the Operator is on duty and operates remote control signal appliances or switches. It is the central point from which the Operator can control and monitor various aspects of a system or process. This term is commonly used in the context of transportation systems, such as railways or air traffic control, where a control station is responsible for managing the movement of trains or planes.

A controlled signal refers to a fixed signal that is under the control of a Dispatcher or Operator and has the capability to display a Stop indication. This means that the signal can be operated remotely by a dispatcher or operator, allowing them to control the flow of train traffic by indicating when a train should stop.

An engine is a unit or combination of units that is propelled by any form of energy. It is responsible for providing the power and propulsion to a train or any other vehicle. In the context of the given question, the correct answer is "Engine" because it aligns with the definition provided in the NORAC - 10th Edition – Definitions.

The correct answer is "Timetable". A timetable is a printed booklet that contains schedules and/or special instructions affecting the movement of trains. It provides information about the departure and arrival times of trains, as well as any specific instructions or changes to the regular schedule.

A block signal is a fixed signal displayed to trains at the entrance of a block to govern the use of that block. This signal indicates whether the block is clear for the train to proceed or if it is occupied by another train. It helps to maintain safe and efficient train movement by controlling the flow of trains in a block system.

An interlocking station is a location from which an interlocking is operated. Interlocking refers to a system of signals and switches that ensure the safe movement of trains by preventing conflicting movements. Therefore, an interlocking station is the correct answer as it is the specific location where the interlocking system is controlled and operated. Control Station, Temporary Block Station, and Dispatcher's Office may be related to railway operations, but they do not specifically refer to the location where an interlocking is operated.

A General Order is a publication used to summarize changes to the Timetable and other instruction manuals. It is issued periodically by the designated officer.

Automatic Train Stop (ATS) is a device on an engine that applies the brakes as a penalty if the engineer fails to acknowledge a cab signal change to a more restrictive indication. This means that if the engineer does not respond appropriately to a change in the cab signal, the ATS will automatically apply the brakes to ensure the safety of the train. ATS is a safety measure that helps prevent accidents by enforcing compliance with signal indications.

A controlled siding refers to a section of a track that is controlled and governed by signals under the control of a Dispatcher or Operator. This means that both ends of the track have signals that are operated by a dispatcher or operator, ensuring that trains can enter and exit the siding safely. This helps to maintain the flow of train traffic and prevent any accidents or collisions.

A temporary block station is a manned station that is established by Bulletin Order or Form D to control the movement of trains. This means that it is a station that is set up temporarily to manage the flow of trains, likely due to maintenance or construction work happening on the tracks. It is not a permanent station like a regular station or an interlocking station, but rather a temporary solution to ensure the safe and efficient movement of trains during a specific period of time.

A home signal is a fixed signal that governs entrance to an interlocking or controlled point. It is used to indicate whether a train has permission to proceed or must stop. This signal is typically located at the entrance of a station or interlocking area and is used to control the movement of trains. It ensures safe and efficient operation by allowing only one train at a time to enter a specific section of track.

The correct answer is "Signal Aspect". In the context of NORAC - 10th Edition Definitions, a signal aspect refers to the visual indication of a signal, as viewed from the direction of an approaching train or on the cab signal display unit in the engine control compartment. This term is used to describe the different aspects or aspects of a signal, such as red, yellow, or green, that convey specific instructions to train operators.

A block refers to a length of track with defined limits where train movements are controlled by block signals, cab signals, or Form D. This means that trains can only move within this specific section of track and must adhere to the signals and instructions given. The other options, such as siding, running track, and main track, do not specifically refer to the defined limits and control mechanisms mentioned in the definition.

A running track is a designated track on which movements may be made by signal indication or at Restricted Speed under the authority of an employee designated in the Timetable. This means that trains can move on a running track based on signals or at a restricted speed, as authorized by an employee specified in the Timetable. It is different from a main track, controlled siding, or interlocking, which have their own specific definitions and purposes.

Speed control refers to a device on an engine that penalizes the engineer by applying the brakes if they fail to reduce the train's speed to the required speed indicated by the cab signal. This device ensures that the train maintains the appropriate speed for safety reasons and prevents accidents or collisions.
