scope:

This Standard defines the Design requirements and the particular Acceptance requirements for all On-Track Plant intended to travel or work on the LU controlled infrastructure.

The requirements for the Design and Acceptance of On-Track Machines and Non- Railborne Plant are contained in LU Standards S1172 and S1174 respectively. The requirements for the Acceptance, Use and Maintenance of all Plant are set out in Standard S1171.

In this Standard On-Track Plant is divided into the following six categories:- 

• Demountable Machines 
• Lightweight Demountable Machines 
• Trailers 
• Lightweight Trailers 
• Road-Rail Machines 
• Trolleys

The four categories of On-Track Plant shown in bold type are as defined in European Standards. The remaining two categories are LU specific.

The requirements set out in this Standard are intended to control the risks associated with the design of On-Track Plant. The risks to be controlled are those which have the potential to affect safety, the train service, the environment and the Company's business, finances and reputation.

The requirements defined in this standard apply to all sections of the operational railway, depots and sidings and to Possession Areas or other temporary work sites established in any of these locations.

The requirements in this standard also apply to On-Track Plant not intended for use in the construction, maintenance and inspection of the LU track, structures, infrastructure of fixed electric traction equipment but which by its presence or use it may represent a risk to the LU train service, operational assets or staff.

The scope of this standard does not include the design or performance requirements for the working function of On-Track Plant in terms or output rate or quality. The expectation is that these requirements will be set out in the Technical Requirement Specifications used for the acquisition of the Plant.
