The procedure covers all signalling equipment on Network Rail infrastructure that is maintained by the Network Rail maintenance function.

The process covers implementation and management of default and alternative maintenance regimes as defined in signal engineering standards NR/L2/SIG/10660 and NR/L2/SIG/10662.

The process for the non availability of a signal maintenance specification is covered along with the process for signal maintenance specifications that contain believed errors.

The procedure for the use of record cards associated with signal maintenance specifications is also covered.
