a AWC stands for Authroity to Work Certificate it authroises somebody to interfere with the signalling system i.e maintaining a set of points, changing relays, but you do not need one if doing standard maintenance as no adjustments or alterations are made. To get a AWC you must be IRSE licensed for the correct work also hold a SCL (Safety Critical License) before the issuer will issue a AWC. There is also a Non - Safety AWC for work on programme machines,t/d's and any of the computer systems used for signalling purposes. They are kept for i think 5 years so any incidents invoving a piece of equipment the last person to work on it can be traced. From what i understand it is a legal document

AWCs are not only applicable to signalling but to almost anything that will or may interfere with the safe operation of trains. This includes electrical and communications systems and equipment other than signalling for which non-safety AWCs are issued. Safety AWCs are also applicable to the tunnel telephone system which is a comms safety system rather than signallling safety system.
The AWC is in fact not only an authority to interfere with something but also to do other works such as commissioning where interference may or may not be required.
An AWC in layman's terms is a permit to work on specified apparatus by a competent suitably qualified, licensed and experienced individual.

From what i understand it is a legal document It used to be that the physical AWC had to be stored for a defined period and then they would be microfilmed and kept in archive, I believe for the life of the asset. |
