Any emergency situation
What is the purpose of issuing T.369 (3b) to the Loco Pilot of a departing train?
To authorize the train to proceed
Which of the following is NOT a method mentioned in the text for advising the Loco Pilot of a departing train?
Verbal instructions

Study Notes
Signals and Their Purpose
- A distant signal serves as an advance warning to drivers of an approaching signal that may require them to stop.
- A facing point signal is a signal that faces the direction of train movement, while a trailing point signal faces away from the direction of train movement.
- A calling-on signal is used to permit a train to proceed into a section of track where another train is already present.
- A shunt signal is used to regulate shunting movements within a yard or terminal area.
Calling-On Signal
- When taken 'off', the calling-on signal displays a white light, indicating that the train can proceed.
- The calling-on signal can be used on occasions such as when a train is instructed to enter a section of track occupied by another train.
- A train must come to a complete stop before taking the calling-on signal 'off'.
- It takes approximately 2 minutes for the calling-on signal to come to the 'off' position.
Distant Signal
- The indication of the distant signal in the caution aspect is a yellow light, warning drivers to prepare to stop.
- In the 'stop dead' aspect, the distant signal displays a red light, requiring drivers to stop immediately.
- When encountering a distant signal showing 'proceed and be prepared to pass the next stop signal at a restrictive speed', drivers should proceed cautiously, prepared to stop at the next signal.
Signal Defectiveness
- If a signal shows a white light instead of a colored light, it is treated as defective.
- If a color light signal is flickering or bobbing and does not show a steady aspect for at least 3 seconds, it should be treated as defective.
IBS and Defectiveness
- When the IBS (Intermediate Block Signaling) is defective, authority is given to the loco pilot at the station to proceed with caution.
- When the IBS is active, the loco pilot should immediately acknowledge the signal and proceed with caution.
Speed Limits and Emergency Situations
- The maximum permissible speed for a goods train while entering the terminal yard is 15 km/h.
- In an emergency situation, an 'off' signal can be put back to the 'on' position for a train.
- The purpose of issuing T.369 (3b) to the loco pilot of a departing train is to advise them of the speed limit and any other necessary instructions.
Loco Pilot Advisory
- The loco pilot of a departing train should be advised after putting back the starter/advanced starter signal through a written or verbal warning.
- A method of advising the loco pilot of a departing train is through a written warning.
