scope:

This Standard applies to mainline and depot sections of the London Underground Railway which are signalled using conventional or transmission based technology. It is applicable to safety and safety-related parts of the signalling system.

This Standard focuses on requirements for the third stage of the lifecycle, Installation, Testing, Commissioning and Handover. However, the totality of requirements contained within the complete suite of Signalling and Signalling Control Standards, see 5.1.2, must be complied with for these systems.

This standard applies to the pre-commissioning and commissioning of signalling systems. It also applies to decommissioning and removal from service (whether temporary or permanent), in relation to its potential impact on the integrity of the remaining system.

This standard applies to in-situ testing on the system and also to site-specific testing taking place away from the railway (for example pre-wired racks or location cases, or data-driven interlockings).

This standard replaces 2-01203-005 A1. The Standard has been re formatted and renumbered. There were no technical changes.

Purpose

The purpose of this Standard is to define the Signalling and Signalling Control Installation, Testing, Commissioning and Handover Requirements which are mandatory to Signalling and Signalling Control Systems used anywhere on the London Underground throughout the whole life-cycle of the system.
