Railway signalling works

Tender description

The Cornwall Capacity Enhancement Scheme (Phases 1 and 2) incorporates the upgrade and re-control of signalling from local control points at Plymouth Panel plus nine mechanical signal boxes throughout Cornwall and increases the capacity of service between Penzance and Plymouth. The scope of this Project is specifically for Phase 1 covering the ‘West’ section only comprising Guide to Rail Investment Projects (GRIP) stages 4b-8 covering the design, construction, delivery and commissioning of: — additional capacity of service between Par signal box and Penzance; — circa 12 new intermediate block signals; — 6 Miniature Stop Lights Crossings (MSLs) and 1 Manually Controlled Barrier with Obstacle Detection (MCB-OD); and — associated signalling works. The project duration is estimated to be 21 months based on current information available and the intended timetable change of December 2018. The principal driver for the CCES scheme (of which the works which are the subject of the contract awarded form a part) is to provide Cornwall County Council with a half-hourly local service from Plymouth to Penzance. The scheme will be delivered in two phases — Phase 1 and Phase 2. — Phase 1 is to provide Cornwall County Council with a half hourly local service between Plymouth and Penzance by December 2018. — Phase 2 is to renew life expired signalling assets and in addition realise operating cost savings with the closure of ten signal box locations. Phase 1 will be divided into two Sections namely East and West with the dividing line at Par Signal Box. Project Description: This Project, and therefore the scope of the contract awarded, is for the West Section — Phase 1 CCES Contract GRIP4b –8 Design, Construct and Commission ONLY — from Par Signal Box to Penzance, which supports the introduction of the new timetable in December 2018. The overall scope of the Cornwall Capacity Enabling Scheme Phase 1 (West) covers the line of route currently controlled by Truro Signal Box: Par Signal Box to Penzance, within the mileage limits described below.
