What is the ‘authority to proceed’?

July 16, 2019, 1:10 PM

Authority to proceed is the formal name for the permission or authorization that allows a driver to take a train into a section of track, in either block or non-block systems of working. It is also known as train working authority. In places where token block instruments are in use, block tokens constitute the authority to proceed. Normally in tokenless block working the authority is implicit in the aspects of signals, although it may be a paper form if signals are defective or missing, etc., or if signalling has been disrupted by equipment failure, floods, etc. In non-block working or under special circumstances, authority to proceed is physically given to the driver on a paper form, or conveyed to him by telephone or walkie-talkie.

Any form of authority to proceed which is in physical form (token, paper form, etc.) is also known in IR rulebooks as tangible authority to proceed, and strict rules govern how it is handled and passed on from one staff person to another.

The following are the most common types of tangible train working authorities in the block system. These are almost always issued on paper forms (except, of course, the block tokens). When these are issued in unusual circumstances (e.g., communications or signalling failure, floods, etc.) in sections where tokenless working is the norm, private numbers must be issued by the station masters concerned along with the paper authority. If communications between stations are disrupted the section controllers can issue paper authority with exchange of private numbers.
