The correct answer is A. T/516.
T/516 is the authority to start a train from a line with a common starter. It is issued by the train dispatcher after the train has been inspected and is ready to depart. The authority is given to the train’s engineer, who is responsible for ensuring that the train is properly prepared to depart and that the track ahead is clear.
T/516 is a written document that includes the following information:
- The train’s number
- The train’s destination
- The train’s route
- The time the train is scheduled to depart
- The name of the train dispatcher who issued the authority
The train dispatcher will issue T/516 only after the train has been inspected and is ready to depart. The inspection will include a check of the train’s brakes, wheels, and couplers. The train dispatcher will also check the track ahead to ensure that it is clear and that there are no obstructions.
Once the train has been inspected and the track ahead is clear, the train dispatcher will issue T/516 to the train’s engineer. The engineer is responsible for ensuring that the train is properly prepared to depart and that the track ahead is clear. The engineer will then start the train and proceed to its destination.
T/516 is a critical document that ensures the safe operation of trains. It is important that the train dispatcher and the train engineer follow the procedures outlined in T/516 to ensure the safety of all passengers and crew.
