Feltham Resignalling GRIP 5-8 Phases 3 & 4 Rail Systems Package

Global Rail Construction Limited (GRCL) has completed a multi-disciplinary GRIP 5-8 rail systems sub-contract encompassing Civil and Structural Engineering including temporary works, E&P and Signalling installation works, covering Phases 3 and 4 of the Feltham Resignalling Project. This project was on behalf of Principal Contractor (PC) Atkins Global for Network Rail’s (NR) Southern region. GRCL is the UK arm of the worldwide Global Infrastructure Group and is a leading provider of design and build services to clients in the rail and transportation sector.

Global Rail Construction Limited’s successful design, installation and handover of this contract supports the culmination and commissioning of these newly signalled areas in August 2023.

The full scope of the main contract has covered the re-control from the existing Feltham Area Signalling Centre (ASC) NX Panel system to the Basingstoke Rail Operations Centre (ROC) on a Resonate IECC Scalable system, and a signalling interlocking re-lock from the existing Staines and Windsor Route Relay Interlockings (RRI) to an appropriate configuration of Computer Based Interlockings (CBI) within the Atkins ElectroLogIXS system. 

All existing lineside signalling infrastructure has been replaced with new equipment including all cabling, Location Case suites, AWS and TPWS, and existing AC track circuit train detection replaced by the Frauscher Advanced Counter (FAdC) Axle Counter system. 7No controlled Level Crossings have been renewed to interface with the new ElectroLogIXS lineside equipment with replacement of the booms, barrier machines, road traffic lights (RTLs), and changing from incandescent bulbs to white light LEDs. 

Feltham Resignalling Project Phases 3-4 Advanced Civils

Principal Contractor Global Rail Construction Limited (GRCL), has completed Feltham Resignalling’s largest civil engineering programme of works, on behalf of Network Rail (NR) Southern Region Capital Delivery.

In October 2020, Global Rail Construction commenced works as the Principal Contractor for the Design and Construction (D&C) of the Advanced Civil Engineering scope of works for Feltham Resignalling Project Phases 3&4. These phases form part of a major Resignalling project to renew life expired signalling, telecoms, and electrical assets for Network Rail, comprising the renewal of 538 Signalling Equivalent Units (SEUs) over 80 miles of railway lines, alongside the introduction of a brand-new signalling system from Atkins – Elix. 

Design activities commenced at pace and site works were meticulously planned as part of a compelling tender methodology and approach utilising weekdays and nights, Saturday nights and several 28 and 52-hour railway possessions during a most challenging project timeframe.

The construction works were further extended to September 2022 to include several additional location case hardstanding’s, PSP compounds, new signal installations, new cable duct routes to existing station platforms and the installation of various new troughing routes – all effortlessly absorbed by GRCL’s in-house D&C team.

Having a railway design and build team, including dedicated project and site management across the civil and structural engineering scope, familiarity with the scheme, having delivered several previous phases and having delivered time pressurised resignalling schemes across Network Rail infrastructure, allowed Global Rail Construction Limited to provide the necessary turnkey solution and complete the project to meet Network Rail’s requirements
