    The demolition and partial reconstruction of Broad Town bridge in Royal Wootton Bassett took place over the May bank holiday, 2016. The new bridge is higher, creating the additional space needed for the overhead electrification wires that will power the new fleet of faster, longer, quieter and greener electric trains to run underneath.

    Modernising the Great Western Route

    We’re modernising the Great Western route to bring passengers faster, more frequent journeys and more reliable services. The project includes upgrading our infrastructure so that the route can be electrified.

    This page shows the work we’ll be doing in Wiltshire and Swindon and when it’s due to take place.

    What we’re doing

    To enable the route to be electrified, we’re installing supporting masts and overhead lines, and preparing the foundations for them (‘piling’). We’ll also be modifying some of the bridges and other structures on the route to create the extra height needed for the overhead lines.

    Severn Tunnel Closure - 12 September to 21 October 2016

    Network Rail has issued a level crossing safety warning urging the public to be extra vigilant when using crossings while the Severn Tunnel is closed for essential upgrade work.

    On Monday 12th September the Severn Tunnel will close for six weeks as Network Rails orange army work day and night to prepare the 130 year old tunnel for electrification - delivering more seats, more frequent services and faster, greener journeys - all part of the company's Railway Upgrade plan

    As a result of the closure, all freight trains and some passenger trains travelling between Swindon and Newport will be diverted via Gloucester increasing rail traffic on the line.

    Level crossings along this route will be busier and Network Rail is urging the public to take extra care and be vigilant when crossing the railway.

    For more information on the closure visit our Severn Tunnel  page

    Royal Wootton Bassett

    Network Rail’s orange army demolished and reconstructed Marlborough Road/Broad Town bridge over the early May bank holiday 2016 , working in collaboration with Wiltshire Council.

    The reconstruction involved raising the height of the bridge to provide the necessary room for the overhead wires that will power the new fleet of longer, faster, quieter and greener electric trains to run underneath. In addition, the footbridge over the railway now forms part of the new structure: a £500,000 improvement funded by Wiltshire Council.

    The old footbridge, which was a separate structure from the road bridge, would have needed replacing in the next five to ten years. Network Rail and Wiltshire Council have worked together to improve the bridge and save costs by incorporating a new footbridge into the new structure.

    Since the reconstruction, work has continued on the bridge and it is due to reopen to traffic on 21st October 2016. The Bath Road and Hunts Mill bridges on the A3102 are due to then close on 24th October 2016 for reconstruction and parapet works. It is anticipated that the road will be closed until early spring 2017. 

    The temporary link road built by Network Rail will continue to serve as a diversion route, avoiding a lengthy alternative for residents

    Please see below for details of the planned work and temporary road.

    Steelwork Installation

    We will shortly be undertaking steelwork installation in the  area shown below as part of our wider plan to electrify the Great Western Railway. This work will involve the installation of masts that will support overhead line equipment (OLE) to power the new fleet of faster, greener, quieter electric trains.  The works will be delivered by High Output Plant System (HOPS) train which installs OLE for railway electrifications projects across the UK.     

    Work on bridges and other structures

    The table below shows bridges and other structures that we need to modify for electrification, along with any temporary road closure and diversions. Work due to start in the future is subject to approval by Wiltshire Council or Swindon Borough Council.

    If you’d like to find out more, why not come along to one of our drop-in sessions? We’ll be pleased to answer any questions you may have.
