Global Rail Construction Ltd is a Principal Contractor and a leading UK provider of design and build services to clients in the rail and transportation sector.
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.
