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.
Global Rail Construction Limited (GRCL) has completed the signalling and telecoms installation and associated civil construction works for the renewal of the following 4No Level Crossings:
- Stroude – a bridal crossing without any barriers that required extensive resurfacing and fencing works and the replacement of 30No track sleepers
- Rusham – a complex crossing that included design and installation of pilling, extensive hardstanding and fencing
- Camberley – a barrier crossing requiring modification, new bases, cable routes, associated fencing and surfacing works
- Chertsey – minor signalling and civils works as there was no new barrier or RTL bases
The works were completed for long-term client Atkins Global, on behalf of Network Rail’s Wessex Route. The completed crossings fall within the Feltham & Wokingham Resignalling project which comprises the renewal of all signalling assets controlled from Feltham Area Signalling Centre (ASC) and Wokingham Signal Box (SB), replacing 9 RRIs with new centralised ElectroLogIXS (CBI) interlockings controlled from Basingstoke ROC.
Global Rail Construction Limited (GRCL) successfully secured a significant Signalling installation sub-contract on behalf of its UK client Atkins. The contract is for Package 1 covering Phases 3 & 4 of the Feltham to Woking Resignalling Scheme and also includes Telecoms, Permanent Way, E&P and associated minor civils installation scopes of work
The contract includes the provision of key engineering resources – using in house personnel – in accordance with the Engineering Management for Projects standard NR/L2/RSE/02009. This includes the necessary disciplined Contractors Responsible Engineers, who are accountable for the day-to-day management and co-ordination of the technical and engineering activities, Construction Managers, Temporary Works Co-ordinators, and a Responsible Manager to fulfil the duties as defined in NR/L3/OHS/019.
This success was awarded following Global Rail Construction Limited’s recent completion of the early advanced scope for Phase 2 covering Sunningdale MCB-CCTV – a full level crossing renewal – in which GRCL completed trackside signalling equipment installations and civils works in early November 2021 and the company was of course delighted to be working once again in partnership with its long-term customer Atkins.
The overall Feltham to Wokingham Resignalling Project covers the renewal of all signalling assets, covered by seven scheme plans, with delivery broken down into six separate Phases that align approximately to the Signalling Scheme Plan boundaries, Feltham ASC Signallers panels and Wokingham Signal Box.
Global Rail Construction Limited (GRCL) was awarded a multi-disciplinary contract on behalf of Atkins Global for the Civil and S&T installation works for a new level crossing at Sunningdale, which falls within Feltham Resignalling Phase 2.
The overall Feltham Resignalling Project covers the renewal of all signalling assets. Its area is covered by seven scheme plans, with delivery broken down into six separate Phases that align approximately to the Signalling Scheme Plan boundaries, Feltham ASC Signallers panels and Wokingham Signal Box.
Within the early advanced scope of Phase 2 was Sunningdale MCB-CCTV, which is subject to a full level crossing renewal – due for completion in November 2021. The scope encompasses life extension works with addition of barrier repositioning and narrowing of carriageway.
Global Rail Construction Limited (GRCL) has secured a multi-disciplinary S&T, Civils and E&P Points Heating remedial contract at London Bridge, on behalf of BAM Nuttall for the Thameslink Project.
As part of the Thameslink Programme, the railway systems for London Bridge were completely remodelled to suit a new layout at the Station and provide substantial capacity improvements to enable amendments to the operational timetabling – this is referred to as the N421 Project.
However, the complexity of managing, staging and delivering the railway systems in order to meet the remodelling programme, necessitated a requirement for the railway systems infrastructure to be surveyed, in order to confirm both its suitability and the requirements to undertake further upgrades and rectifications as required.
Global Rail Construction Limited are among a team of specialist rail contractors working in a highly coordinated manner to deliver these important upgrades for Network Rail. The in-house team of multi-disciplinary experts from Global, have worked almost entirely within a live, operational environment, interfacing daily with equipment that is switched on, in a wholly compliant manner.
The specialist discipline support services undertaken by Global Rail Construction Limited cover the entire end-to-end design and build scope of the Signalling, E&P and Ancillary Civil Engineering programme.
Following Global Rail Construction’s notable success in securing a Principal Contractors licence, its signalling division was invited to provide the most advantageous offer to fully manage a project on Network Rail’s (NR) Wessex route. The scope of works included for planning, surveying, installing and commissioning of 509No Hima-Sella Tracklink 3 beacons, including the careful recovery of the existing beacons for refurbishment and re-use, all under SMT conditions.
The system known as Automatic Selective Door Operation (ASDO), provides the train operator – in this case South West Trains – with technology that compares the length of the train with the length of the platform, sending a signal to the driver so that only the correct amount of doors on the platform side are opened.
With more people travelling by train, many train operators are increasing the number of carriages and whilst the infrastructure owners are also increasing platform capacity to afford the extended trains, there will be many stations that will not have sufficient platform length to allow all doors to open.
The principal function of this technology is contained within an electronic beacon installed at each station location, which is fitted to the track at a pre-determined datum point to the existing sleepers and is mounted within the mid-point between the rails known as the 4ft.
The beacon itself is a passive component that utilises radio frequencies and communicates with a beacon reader, which is fitted to the train and then this in turn decodes the data taken from the beacon.
Having provided a comprehensive offering Global Rail Construction were contracted by Network Rail in the Summer of 2014, to meet two key project milestones as part of a two-phased programme in October 2014 and December 2015.
