Signal failure advised to the driver through the station in rear will be inform A. T/369 B. T/370 C. T/369(3b) D. None of these

The correct answer is C. T/369(3b).

T/369 is the general form of a train order, and (3b) is the specific form used to advise the driver of a signal failure. The order would be transmitted to the driver through the station in rear, which is the station immediately before the one where the signal failure has occurred.

A. T/369 is the general form of a train order, but it does not specifically address signal failures.
B. T/370 is the form of a train order used to advise the driver of a train approaching a closed switch.
D. None of these is the correct answer.
