This document sets out requirements for the lineside signalling system to be compatible with train operations and guidance on their application.

Minor changes throughout Parts 2, 3, 4 and 5 to clarify the intent of requirements and guidance. Updates to requirements and guidance in Part 3 to enable the withdrawal of Network Rail document NR/L2/SIG/19609 issue one Requirements for Colour Light Junction Signalling, to reflect current good practice for 'lamp proving' and the application of banner junction indicators. Updated definitions and references. Minor editorial changes than have no material impact, including alignment of terminology with that used in other CCS standards.
