Rail Projects

West Coast Mainline Power Upgrade

Client: Birse Rail
Value: Various

 

The overall project is for the design, supply, installation, testing and system commissioning of 9nr new 25-0-25kV traction power supply substation buildings, substation compounds and associated Overhead Line equipment (OLE) for power trackside electrical feeding and sectioning equipment, High Voltage (HV) cabling and traction earthing and bonding systems.

GPL were contracted to undertake the FRC, Groundworks and Fencing at 3 locations – Sandon and Whitmore in Staffordshire and Atherstone in Warwickshire. The works comprised:

Where necessary, trackside works were completed at night during line possessions.

Sandon

The FRC Works at Sandon comprised of a base slab for the Modular Building and 2nr single ATS Bases.

Whitmore

At Whitmore, the FRC works comprised of a Modular Building Base Slab, a single ATS Base, a double ATS Base with dividing Blast Wall and 2 nr Cable Chambers. One of the Cable Chambers was trackside and required the installation of sheet piling during possessions to facilitate construction.

Atherstone

At Atherstone the FRC Works comprised of a base slab for the Modular Building, 2 nr single ATS Bases and a cable chamber.

Platform Extension Works – Marsden, Mirfield and Mossley

Client: Buckingham Group
Value: £275k
 

The platform extensions of Mossley, Marsden and Mirfield Stations included the demolition of existing platform ramps and construction of extensions to existing platforms. The works included fully compliant platform construction up to and including surfacing and line painting together with the installation of new lighting columns and signage. All new drainage was connected to the existing network and the works also included the installation of new platform fencing.

Though appearing as relatively small works, each station presented its own unique challenges. At Mossley the platform extension ran adjacent to a large rock face; at Marsden there was a large existing drainage tank behind the retaining wall and at Mossley, the works had to be constructed within difficult access possessions.

 

 Buckshaw Parkway Railway Station, Chorley

Client: Volker Fitzpatrick
Value: £830k

 

The main contract completed by Volker Fitzpatrick was to design and construct a new station serving the new Buckshaw Parkway Village. It included a fully accessible park and ride facility with a station building on one side, two six-car length platforms and car parking for 200 cars. The platforms were linked by a DDA compliant footbridge and housed two 20-person waiting shelters and associated new utilities.

GPL were contracted to construct the platforms; the substructure to the Station Building; foundations to the footbridge and install ducting and drainage within the footprint of the platforms.

Leicester Road (Melton Mowbray) – Road Bridge over Railway

Client: GallifordTry Rail

The works at Leicester Road were very similar in nature to those undertaken at Enderby – see below for detailed description of works.

Enderby to Whetstone, Road Bridge over Railway, Leicester

Client: GallifordTry Rail

GPL were contracted by GTR to construct a new replacement road bridge spanning the railway line near Leicester. The existing road was to be kept open for all but a short duration which necessitated constructing an off-line insitu concrete bridge deck and having it slid into position once the existing bridge had been demolished.

GPL were also responsible for the construction of insitu concrete galleries, wing walls and approach walls in challenging circumstances that necessitated working within night time possessions to maintain programme.

Crewe Train Station Water Mains Renewal

Client: GallifordTry Rail
Value: £400,000

GPL successfully tendered for this project through the “A” Site portal online. The works involved the renewal of the existing water mains that feed the whole of the Train station and its depots in the surrounding area. The existing mains were over 100 years old? And the amount of water that was being wasted due to leaks was unsustainable, GPL had to carry out operations which involved crossing tracks, excavating and dealing with contaminated ground, Slip-lining existing mains and making connections to multiple buildings that belonged to the train station. Testing and reconnection to the main provider network was undertaken successfully with no disruption to the local businesses.

Gisburn Gabion Retaining Wall for Network Rail

Client: Murphy
Duration: 4 Weeks
Value: £100,000

GPL was contracted by Murphy on behalf of Network Rail to install a Gabion Retaining wall to a railway embankment in Gisburn, Lancashire to help stabilise it from potential movement. The Gabions were constructed of heavy duty wire mesh; the client requested that the facing of the gabions be dressed to provide more stability to the wall as after, ground achors would be drilled in to the embankment; pockets were placed through the wall to allow access for the drilling rods.

Altrincham Train Station Metrolink Refurbishment

Client: GallifordTry
Date: August 2009
Duration: 4 Weeks
Value: £550,000

GPL undertook a 4 week Fast track contract to carry out the upgrade of the train station platforms. This consisted of removing and breaking up the existing tarmac and platform copers, building new access ramps and new platform drainage and replacing the old copers for new ones along both platforms.

The train station was shut down for the 4 weeks which allowed us to work 24/7 working from off the train track using Road rail equipment, access was gained by using the train track gaining a entry point about 500 metres away. The station was ready for opening 2 days before handing back to the client.
