GRIP stage 3 (Option Selected) and
GRIP stage 4 (Single Option Development)
Client: Jacobs
Project Overview
Billinghurst Station is located on the Three Bridges to Portsmouth Harbour line. SB was built in 1876 by Saxby & Farmer, and the mechanical frame was the original from that date with 18 lever positions with electro mechanical interlocking.
The platforms were to be extended towards Three Bridges to facilitate the use of class 377 rolling stock of 20.4m car. The extensions were required to facilitate 8-car train of 163.2m length. The width of the extended platform was maintained a minimum of 3m, although the existing platform width was to be taken into account, when determining the width of the extended section(s). The extension included lighting and public address system.
During GRIP stage 3, two options were discussed and explained in Option Selection Report produced by Softech along with Scheme sketches to extend the length of platforms 1 & 2 at Billinghurst to accommodate 8 cars and as well as 12 cars. The project developed the preferred single option from GRIP 3 study.
All required signalling works for this scheme were defined by and shown on the Billingshurst Platform Extensions Signalling Scheme Plan along with other GRIP stage 4 documents.
