scope:

The extent of the application of this standard is as follows:

new trains supplied to LU for operation by LU or its agents over LU infrastructure shall comply with this standard in its entirety;

new trains supplied to LU for operation by LU or its agents over LU and Network Rail (NR) infrastructure shall comply with this standard in its entirety and with Railway Group Standard (RGS) GM/RT2452;

existing trains operated by LU or its agents over LU infrastructure shall comply with this standard as far as reasonably practicable;

existing trains operated by LU or its agents over LU and NR infrastructure shall comply with this standard as far as reasonably practicable (refer to the Standards Code in the PPP contract) and with RGS GM/RT2452;

new trains and existing trains certified as fit for NR infrastructure operated by a Train Operating Company (TOC) over LU infrastructure shall comply insofar as these do not conflict with RGSs with, for example, the requirements for gauge, route availability (mass, axle loads, length, etc) radio communications, braking and train protection;

trains which previously have been operated by a TOC over NR infrastructure, supplied for operation by LU or its agents over LU infrastructure, shall comply with this standard, as far as reasonably practicable;

trains which previously have been operated by a TOC over NR infrastructure, supplied for operation by LU or its agents over LU and NR infrastructure shall comply with this standard as far as reasonably practicable and with RGSs where appropriate;

new and existing non-passenger trains and vehicles shall comply with this standard where appropriate.

Existing trains, operating as described in c) and d) above which are modified shall:

comply with this standard, as regards the modification and;

comply with this standard as far as reasonably practicable, as regards other items revealed by or related to the modification.

This Standard applies to all new rolling stock in its entirety and to existing rolling stock so far as is deemed reasonably practicable. When existing rolling stock is modified then it will be deemed to come within the scope and the degree of compliance shall be reassessed for reasonableness.

In this standard it shall be construed that:

the following, being words which are used in the text according to the derivation of the particular requirement stated, are interchangeable:

"rolling stock" and "train(s)";

"passenger" and "customer".

"degraded" is descriptive of all states or conditions, except "normal".

This standard replaces 1-180 A1.

Purpose

The purpose of this standard is to define the requirements, documentation and processes for the operation of the rolling stock on the London Underground Limited (LU) network, in order to demonstrate that the trains and their systems are safe and that all residual risks are As Low as Reasonably Practicable (ALARP).

This Standard exists to define:

the top level requirements for the use of trains in the LU environment, ensuring that they are fit for purpose, and minimise the risks to the system, staff, passengers, members of the public and the environment;

the performance requirements of the train under normal and degraded operating conditions, so that emergency recovery procedures are used as rarely as possible, and operators are supplied with appropriate information to ensure timely recovery of trains from defects;

the general standard of equipment to be provided on passenger trains, including the resistance to vandalism of all types;

the operating systems and interfaces appropriate for the infrastructure in which the trains operate including the visibility from and the visual external appearance of the train.
