The form number of authority to proceed without line clear is ________. A. T/1408 B. T/A1408 C. T/B1408 D. None of these

The correct answer is: A. T/1408

An authority to proceed without line clear (APWLC) is a document that allows a train to proceed without having to wait for a line clear signal. It is used in situations where there is a risk of a train being delayed or stopped due to a signal failure or other obstruction.

The APWLC is issued by a train dispatcher and is valid for a specific period of time. The dispatcher will specify the route that the train must take and the speed that it must travel. The train must also have a qualified crew on board.

The APWLC is a safety measure that helps to ensure that trains can operate
