NR RT/E/S/21010 ISSUE 1 PDF

This specification applies to all point-to-point equipment used to enable remote equipment to be controlled and monitored from an electrical control room (ECR) or control centre.

The specification does not include requirements for site installation or commissioning works.

The document is to be read in conjunction with Railtrack Line Specifications RT/E/S/21000, "Operational, Environmental and General Requirements for Remote Control Equipment for Electrical Distribution Systems" and RT/E/S/21011, "Data Communication Circuits Associated with Point-to-Point Equipment Used on Electrical Distribution Systems", and the relevant procurement specification.

Purpose

This specification states the requirements for point-to-point equipment used to extend control and indication from a supervisory control and data acquisition (SCADA) outstation to a lineside location where a remote device(s) associated with an a.c. or d.c. traction network is sited. The remote equipment is generally positioned at a distance from the parent point exceeding 500 metres and, typically, is a motorised switch.
