Clacton Resignalling Scheme

CLIENT: Atkins
DATE: May 2021
LOCATION: Clacton-on-Sea

Global Rail Construction Limited (GRCL), has successfully completed a railway civil engineering design and build programme of works on behalf of partner Atkins Global, to support the upgrade the signalling systems in the Clacton-on-Sea area. 

The Clacton Resignalling Projects’ principle driver was the asset condition of the interlocking and associated track infrastructure at the throat of Clacton-on-Sea station.

Much of the signalling in the area dated back to 1958 and utilised a lever frame dating from 1891. There was a mixture of semaphore and colour-light signals, controlled by a mechanical/electro- mechanical lever frame. There was also a mechanical ground frame at Clacton Station. The existing signalling equipment has been previously subject of life extension works in both 1996 and 2004.

Many components were obsolete and only available on a repair and return basis. Most of the existing location cases had considerable corrosion. The signalling uses some single-cut circuits which are the subject of ORR concern. Searchlight signals were installed on this line, with known Wrong Side Failure (WSF) modes. P-Style relays in the lower portion of the box were recognised as susceptible to sliver migration. So, these works, will minimise maintenance and reduce whole life costs.

Automatic Selective Door Operation (ASDO) Project

CLIENT: Network Rail
DATE: Dec 2015
LOCATION: London and the South West (Wessex Route)

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.


Station Works – Design and Construct

DATE: Jan 2015

Selby Swing Bridge

CLIENT: Siemens
DATE: Dec 2012

Global Rail Construction were selected by Siemens as design and build civil engineering contractor for a Horizontal Directional Drill (HDD) that was required to cross under a Grade 2 listed building, the Great River Ouse, Ouse Road and the East Coast Mainline railway in the heart of Selby town centre.

Utilising their in-house multi-disciplinary design team, Global Rail Construction were able to offer Siemens a complete design and build solution.

The civil engineering works, which formed part of the Selby Rail Swing Bridge Signalling Interlocking Renewal being undertaken by signalling product specialist Siemens, were being specifically undertaken to renew the existing electricity cables, which had been installed in 1956 and were located under the river.

The project consisted of the replacement of the swing bridge cabin signalling interlocking onto a new interlocking building, incorporating new lineside equipment from locations 128, 129, 130 and 131, which also required cables to traverse into the river at this location. The conventional approach of simply running the signalling cable across the bridge was not appropriate, as one 40m span of the swing bridge – which was built in circa 1900 – allowed river traffic to pass. Hence, Global Rail Construction designed a suitable ducted solution to carry telecommunication, signalling and power cables on behalf of their client.


Car Parks and Railway Platforms Frameworks

CLIENT: Irish Rail
LOCATION: Nationwide, Ireland

Civil Engineering is at the core of Global Rail Services’ offering. The company have constructed new station car park & Platforms facilities and built and upgraded many station new platforms to both increase capacity, and to comply with the Disability Discrimination Act (DDA), across mainline and metropolitan stations throughout Ireland.

These works also encompass electrical, mechanical, CCTV and telecommunications installations and upgrades, where Global Rail Services are able to call upon their in house M&E department to provide the necessary engineering and delivery support.

It is this turnkey solution that has enabled Global Rail Services to provide comprehensive project solutions – providing Irish Rail with contract surety.

The works formed a fundamental part of the Irish Rail’s programme to improve passenger experience and increase capacity, at both mainline and metropolitan railway stations throughout Ireland.

The scope for the car parks involved the complexities of working adjacent to a live railway station and required professional community engagement to ensure that patrons and stakeholders were fully informed before and during the works.

The platform works involved close liaison with Irish Rail’s railway systems signalling team and also their track infrastructure engineers. Although, Global Rail Services undertook any associated track modifications as part of another framework with Irish Rail for Permanent Way.


Lethbridge Superstructure Replacement Works

DATE: May 2016
LOCATION: O Connor Road, Victoria

Global Rail Australia secured via competitive tender the contract on behalf of regional train operator V-Line in 2016, to provide a full turnkey civil and structural engineering service, for the fabrication and installation of a new bridge superstructure in Victoria.

The existing Railway Bridge, sits on the Ballarat passenger service line at O’Connor, serving the regional districts of Victoria.

V-Line as part of a large programme of rail upgrades, selected Global Rail Australia as the preferred contractor to replace the life expired wrought iron and timber structure with a newly fabricated concrete superstructure.

The works required careful planning and involved detailed surveys, production of detailed shop drawings for the new deck and walls, pre-installation testing of the fabricated concrete sections and the replacement of the bridge during a three-day occupation of the railway line.

Scaffolding was erected on O’Connor Road adjacent to the bridge abutments and during the railway closure, the existing tracks were lifted out and the rail ballast removed, to facilitate the removal of the old structure.

The new bridge deck and walls were then lifted with a 100 tonne crane – fully facilitated on site by the Global Rail Australia’s specialist civil and structural engineering crew. These were then carefully lowered into position, where Global’s site engineering team could fix them into their correct positions.

Due to the railway closure alternative bus services were laid on to enable passengers affected by the closure to travel around the works.

Works were completed on time and the project was handed back on 22nd May 2016.


Transport Infrastructure Ireland Building Framework – Dundrum Station House Refurbishment Works

CLIENT: Transport Infrastructure Ireland (TII)
LOCATION: Dublin, Ireland

Currently working on their third consecutive prestigious four-year railway framework for building works, Global Rail Services Limited (GRSL) were awarded a contract to completely refurbish a historical listed building at Dundrum Station.

The specialist building framework which was let by the organisation that maintains Irish Railways – Transport Infrastructure Ireland (TII) – was won by Global Rail Services following competitive tender giving TII the mechanism to let individual packages of works to their preferred contractors of up-to €1m.

Having successfully delivered many contracts throughout the framework, TII selected Global Rail Services as their partner of choice for the sympathetic refurbishment of a listed heritage structure known as ‘Dundrum Station House’ and demolition of an adjacent two storey derelict structures parallel to the existing live Dundrum LUAS stop.

The completely derelict building – which had been subject to intense vandalism – was to be carefully re-built and restored to its former glory and converted into a café and two offices. Works included structural alterations and repairs to the building, brickwork restoration, full heritage internal refurbishment works and the provision of new mechanical and electrical installations throughout – all in accordance with exacting conservation standards.

The scope of works also extended to transforming the surrounding areas by demolishing an adjacent dilapidated industrial unit to form a new car park including cycle storage, providing external lighting, CCTV and external landscaping.

The works formed a fundamental part of the TII’s programme to improve passenger experience at metropolitan railway stations by refurbishing commercial buildings and structures in and around them.

The scope involved the complexities of working adjacent to a live railway environment, materials management and site logistics, all whilst delivering works to an exacting heritage specification. GRSL have an experienced project management team and held weekly site progress meetings to ensure works were being delivered to the required standard.

Having a multi-disciplinary in-workforce including Building, Civil and Structural Engineering, M&E and General Construction along with in-house site management, allowed Global Rail Services Ltd to provide a compelling solution, deliver to program and produce a lasting legacy for the building and the surrounding area.


Connolly Loop Line, Permanent Way Replacement works

CLIENT: Irish Rail
LOCATION: Dublin, Ireland

Global Rail Services provided a most compelling offer to Irish Rail and were awarded a €1.1m track renewal contract, to remove and replace 1km of railway track on both the Up and Down lines between Tara St and Connolly Station.

The works were to be completed during restricted working hours – 24/7 possession working – commencing on St Stephens’s day and for 14 consecutive days thereafter throughout the Christmas period.

Having a vastly experienced project engineering team, enabled Global Rail Services to put together a fully planned and detailed methodology to deliver a huge volume of critical infrastructure works, which formed part of Irish Rail’s railway upgrade programme.

With access over ¾ of a mile away from the site and the works limited to a single line for both removal of the old and delivery of the new track materials, Global Rail Services meticulously prepared a detailed hour-by-hour programme for all activities. This included full contingency provision.

With this is mind, early stage preparation works were undertaken to build the track panels in readiness for the works. A bill of materials was also prepared, so that all materials could be delivered, quality checked and stacked ready for the Christmas shutdown.

The works also involved the re-alignment of a bridged line over the centre of Dublin, which required advance notices and planning and also the replacement of curved check rails.

Having a strong in-house capability of 60 track staff provided Irish Rail with the confidence that Global Rail Services were the partner of choice and this proved to be a wise decision.

With strong supply chain partnership with their plant and machinery providers, Global Rail Services provided full project surety, enabling the works to be handed over defect free, on time and to the required budget.
