scope:

This Standard applies to all new passenger rolling stock in its entirety.

This Standard applies to existing passenger rolling stock in respect of the Engineering Management (Part 3A) and the Maintenance Sections (Parts 3U to 3AA). Alternative processes, which provide an equivalent level of control and records, may be used subject to agreement with the HoRS.

The technical requirements defined in this Standard (Parts 3B to 3T, plus 3BB) are not intended for retrospective implementation on existing passenger rolling stock (other than as part of appropriate modifications).

When existing passenger rolling stock is modified, the scope and degree of compliance with the technical requirements defined in this Standard shall be assessed for reasonableness and agreed as part of the development and approval of the Particular Specification for that modification.

The Standard provides requirements and process which shall be applied as follows;

a) The engineering and safety management section mandates requirements and processes (or approved equivalents - see Section 2.2 above) concerning the engineering controls to be applied when undertaking any work within RS Asset area.

b) The maintenance management section defines the minimum requirements to be satisfied in respect of the train maintenance for any passenger rolling stock fleet.

c) This standard provides the minimum technical requirements which need to be satisfied for any passenger rolling stock design or major modification. In addition, it provides a series of check lists, prompts and reminders of key elements which need to be addressed as requirements within a Particular Specification.

d) This standard provides the technical requirements which need to be satisfied, where practicable, for any passenger rolling stock minor modification. In addition, it provides a series of check lists, prompts and reminders of key elements which need to be addressed during the development of the modification.

This Standard shall not be used as a formal contract document but shall principally be used as a reference document by technical and project staff within LU during any of the following activities;

a) New design of a passenger rolling stock product,

b) New build of an existing passenger rolling stock product,

c) Modification of a new design of passenger rolling stock product post its initial approval,

d) Modification of an existing design of a passenger rolling stock product; for such modifications, the scope and degree of compliance with the Technical Requirements defined in S2180 shall be assessed for reasonableness,

e) Development or modification of the train maintenance regime for any passenger rolling stock

In preparing this standard the following assumptions were made and Section BB3.1.4 requires the project to validate these assumptions and formally raise any identified issues;

a) The traction power supply will remain a 4 rail system with positive and negative conductor rail power supply,

b) The traction power supply voltage will be progressively increased as far as possible,

c) The track gauge will not be changed,

d) The introduction of new or modified rolling stock must not require an extended line closure(s),

e) Inter running between new and existing stock on a line, in passenger service, must be possible,

f) The normal operational mode on a line will progressively move from "manually driven" to "automatically operated",

g) The two basic designs of LU rolling stock (tube and surface) will be retained,

h) Cleaning of both deep tube and sub surface tunnels will be progressively enhanced to remove accumulated dirt and dust.

Purpose

This standard shall not be issued to suppliers as a formal Contract document. The principal purpose of this standard is to act as an internal LU reference document for;

a) Defining the detailed engineering and safety management requirements for effective control of passenger rolling stocks throughout their whole life.

b) Defining the maintenance management requirements for all passenger rolling stocks throughout their whole life.

c) Use during the preparation of Particular Specifications for passenger rolling stock design or major modification, including the relevant maintenance requirements.

d) Use during the preparation and development of minor modifications either by internal LU rolling stock engineers or by Third Parties.

When undertaking project work falling within the scope of 1.1 c above, it is expected that the requirements shall be incorporated and, where appropriate, supplemented within the Particular Specification produced by a specific project. In addition to expanding the requirements of this standard as appropriate to suit the LU Client Brief, it is intended that the Project will further consider the various risk aspects that this standard highlights and ensure that these risks are managed by the Particular Specification in as much as they may be relevant to the Project scope.

All requirements are contained in Section 3 "Requirements". Due to the bulk of material and to facilitate ease of use in cascading requirements, there are 28 alphabetical "Parts" to Section 3.

The last "Part" of Section 3, Part BB, contains non topic specific requirements with which an LU Project must itself comply.

This standard also provides access to information about techniques which have proved successful in LU use.
