scope:

This Standard applies to all Purpose Built EVs in its entirety. 

This Standard, excluding the "Purpose Built" Sections, applies to any other "new to LU" or "previously approved for use on LU" EVs. 

This Standard applies to existing LU owned EVs (i.e. which pre-date the publication of this Standard) in respect of the Maintenance Section (Part H) which operate in Traffic Hours and shall also be used as guidance in developing the maintenance requirements for non-Traffic Hours vehicles. 

The technical requirements defined in this Standard for Purpose Built vehicles are not intended for retrospective implementation on existing engineers vehicles (other than as part of appropriate and agreed modifications). 

When existing EV's are to be 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 of the new "RS req's for EV's" Standard mandates requirements and processes concerning the engineering controls to be applied when undertaking any work within the RS Asset area.

b) The maintenance Section defines the minimum requirements to be satisfied in respect of the train maintenance for the brake and air system on any Engineers Vehicle or fleet of vehicles.

c) This standard provides the minimum technical requirements which need to be satisfied for the brake system on any new EV design or a major modification to an existing EV design. In addition, it provides a series of check lists, prompts and reminders of key elements which need to be addressed as requirements within a Braking Specification.

d) This standard provides the technical requirements which need to be satisfied, where practicable, for any minor modification to the Brake System of an existing EV or EV fleet. 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 an EV brake or air system product,

b) New build of an existing EV brake or air system product,

c) Modification of a new design of EV brake or air system product post its initial approval,

d) Modification of an existing design of a brake or air system EV product. For such modifications, the scope and degree of compliance with the Technical Requirements defined in this Standard shall be assessed for reasonableness and application,

e) Development or modification of the maintenance regime for the brake or air system on any EV.
