Organization: NR
Publication Date: 7 December 2019
Status: active
Page Count: 57
scope:

This Network Rail standard specifies the requirements for the design and manufacture of new switch and crossing units, switch and crossing assemblies and expansion devices or expansion device panels. It also specifies those components to

be used in the manufacturing process and methods of application.

This standard applies to the manufacture and despatch of new S&C and expansion devices for use in Network Rail controlled infrastructure. It also applies to trial assemblies where these are required by the purchaser.

Purpose

This standard is intended to control the risk of incorrect components and processes being specified during the manufacture and assembly of switches and crossings (S&C). It refers to component specifications and controls found in other Network Rail

standards. It specifies the components and processes that are subject to individual and collective product acceptance. It specifies the controls in place intended to minimise the risk from non-standard designs of S&C.
