If your train is stopped by an emergency application of the brakes or severe slack action occurs while stopping, and an adjacent main track or control siding may be obstructed, the immediate action required is to warn other trains by making an emergency call over the radio. This call should include important information such as the train ID, direction, check-in location, and notify the RTC (Rail Traffic Controller). This is necessary to inform other trains about the potential obstruction and ensure their safety.

Submit
10. What is required if a yellow-red flag is encountered without a corresponding GBO item? (1100)

Explanation

If a yellow-red flag is encountered without a corresponding GBO item, the correct action is to proceed prepared to stop short 2 miles beyond the yellow-red flag. If no red flag is displayed, the train should proceed at restricted speed until the RTC (Rail Traffic Controller) confirms that no planned work is in effect at that location. This ensures safety and allows for proper coordination with the RTC to prevent any potential conflicts or hazards on the track.

Submit
11. What is required before or during shoving movements? (502)

Explanation

Before or during shoving movements, several requirements must be met. Firstly, the engineer in charge must conduct a job briefing, which includes discussing the means of communication and the type of point protection to be used. Secondly, the employee directing the shoving movement must not be engaged in any unrelated task during the move. Lastly, when cars are being shoved on a single main track, controlled siding, or any track where CTC is in effect, the movement must be made at restricted speed, unless permission is granted by the capital RTC or control operator, and the movement remains within the block. All of these requirements are correct and must be followed.

Explanation

The correct answer is "It depends on whether the authority indicates Switch Yes(SW-Y) or Switch No (SW-N)." This means that the limits of a Track Authority may or may not include the Foul Zone of a switch, depending on the specific instructions given in the authority. If the authority indicates "Switch Yes," then the limits would include the Foul Zone. If the authority indicates "Switch No," then the limits would not include the Foul Zone.

Submit
14. When required to move that restricted speed, at what speed must a train or engine proceed? (518)

Explanation

When required to move at restricted speed, a train or engine must proceed at a speed that allows them to stop within one half the range of vision short of any potential hazards such as trains, engines, railroad cars, roadway workers or equipment, stop signals, switches, or improperly laid rail lines. They must also be looking out for broken rails. The maximum speed allowed in this situation is 20 mph.

This is important to ensure the safety of other trains on the track and to inform the control authorities about the situation. Backing up to get behind the signal may not be necessary or safe in all situations, and notifying the train dispatcher is not mentioned as a specific requirement in this scenario. Therefore, the correct answer is to warn other trains by radio, stop immediately, and notify the RTC or control operator.

Submit
18. When transmitting and copying mandatory directives, how must station names be shown? (1001)

19. When is a train considered Delayed Within a Block?

Explanation

A train is considered Delayed Within a Block when it has entered a block on a proceed indication that does not require restricted speed, and the train either stops or its speed is reduced below 7 MPH. This means that if a train is given permission to proceed at a normal speed in a block, but it either stops or slows down to a speed below 7 MPH, it is considered delayed within that block.

Submit

Submit
22. Your train is approaching a scheduled station. Where there are two or more tracks. What do you do? (531)

Explanation

Before allowing passengers to get on or off the train at a scheduled station with multiple tracks, it is important to ensure the safety of the passengers. This includes checking the location of any other trains that could potentially pass underneath the train. However, if there is a physical barrier separating the tracks, such as a fence or wall, then it is safe to allow passengers to board or disembark without checking for other trains.

Submit
23. Your train is proceeding at restricted speed after passing a signal indicating stop and proceed. The lunar marker on the signal was not displayed. If a facing point spring switch is encountered within that block, how do you proceed? (706)

Explanation

When the lunar marker on the signal is not displayed, it indicates that the signal is not functioning properly. In such a situation, it is necessary to take extra precautions. Therefore, the correct approach is to stop and test the switch before passing over it to ensure that it is properly lined. This ensures the safety of the train and prevents any potential accidents or derailments.

Submit
24. What does it mean when Track Authority includes the instruction Switch Yes (SW-Y) at a control point named as one of the track limits? (1003)

Explanation

When Track Authority includes the instruction Switch Yes (SW-Y) at a control point named as one of the track limits, it means that the trackage between the opposing absolute signals of that control point is included in the Track Authority limits. This means that the train is authorized to proceed through that section of track and the switches at that control point can be operated without seeking permission from the operator.

Submit
25. What is the definition of a Foul Zone? (Definitions)

Explanation

A foul zone refers to a segment of track between the switch points and the clearance point of a switch. In this area, equipment can potentially be struck by equipment on an adjacent track. This definition highlights the specific location and purpose of a foul zone, distinguishing it from other options such as a location where equipment will not be struck by adjacent equipment or a location identified by paint, sign, or insulated joints indicating the limits of a crossing circuit.
