scope:

There are plug couplers and plug coupled units that are already accepted and in use on Network Rail infrastructure, and for the purposes of this standard, it is not expected to retro-fit a new type of coupler.

The requirements defined in this standard apply to the interconnection of lineside railway signalling equipment using a plug coupled connection for tail cables: typically linking the location case and the trackside equipment, including the use of a disconnection box or in-line connection where appropriate. The requirements also apply to lineside multicore cable: typically linking apparatus housings.

Plug couplers will offer benefits in terms of installation, testing, maintenance and renewals when appropriately utilised, however these activities are not part of this specification. The utilisation of plug couplers for projects and maintenance is described within NR/GN/SIG/CAT005.

This standard includes background information which may be of use to signalling designers, installers and maintainers. However, signalling design principles, testing techniques and Network Rail's implementation rules are excluded from the scope of this standard other than where germane to the plug coupler product itself.

Purpose

The aim of this standard is to set out Network Rail's requirements for plug coupler products. This standard includes construction details and performance requirements for plug couplers that are intended for use with approved Network Rail trackside signalling equipment and lineside circuits.

Plug coupler products submitted by manufacturers will be assessed against the requirements within this standard. Proposals for suitable products should be supported by evidence to demonstrate compliance with this standard when seeking Network Rail product acceptance.

Requirements for the use of plug couplers approved against this specification with previously approved equipment types are contained in Appendix A.
