LUL - G3220
Plant approval and operational requirements
|Publication Date:||1 September 2016|
This Guidance applies to all portable and transportable plant except basic hand tools (eg. spanners, hammers, shovels etc.) and battery powered hand tools that have not been designed or adapted for use on a railway.
For the purposes of standards S1171-4, plant is sub-divided into three main groups with similar attributes and requirements all of which have differing requirements for acceptance:
On-Track Machines - Rail mounted machines that conform to the definition of a train , or part thereof and as such are able to run in traffic hours as well as be able to travel and work within possessions and specified areas and in some cases traffic.
On-Track Plant - Rail mounted machines that do not conform to the definition of a train and only operate in possessions, specified areas or Engineering Hours. These machines are subdivided a further level into the following categories: Demountable Machines, Road-Rail Vehicles, Rail Trailers, Lightweight Demountable Machines and Trolleys.
Non-Railborne Plant - All other items of plant which are not rail mounted; the diversity of plant in this category is very extensive and ranges from equipment such as large cranes and construction equipment to small items of measurement equipment and powered hand tampers.
Standard S1171 only applies to plant intended for use or storage anywhere on the LU Infrastructure. This excludes:
The interior of enclosed workshops or premises that are not accessible to the Company's customers.
Fully enclosed sites that are located away from the track and separated from the track by a physical barrier which is clear of the Structure Profile and sufficiently extensive and robust to prevent plant within the worksite or construction site from interfering with the operation of the railway - for example hoarding w ould not be robust enough to prevent a large excavator from potentially interfering with the safe operation of the railway as it would be easily overcome/knocked down.
The above must however also take into account any equipment that may transmit electromagnetic radiation (eg. scanners, generators etc.) which may have an affect on the signalling system with regards to EMC.
This Guidance Document supports LU Category 1 Standard S1171 All Plant - Acceptance, Use and Maintenance and gives guidance on the requirements of formal acceptance, the applicability of the standard and the steps that must be completed to gain approval for items of plant for use on the London Underground Infrastructure.
This document also outlines the operational requirements for the safe use and maintenance of plant to be complied with post approval, outlines the key stakeholders and their varying levels of responsibility.
