The extent of the upgrade work to prepare the Severn Tunnel for electrification has been shown in a new time lapse video released by Network Rail.
The footage features the installation of over 13km of conductor rail in the 130-year-old tunnel which took place the six week closure (12 September to 21 October). The work was carried out as part of Network Rail’s railway upgrade plan.
Network Rail said that an extensive amount of work had also completed to lower the track in the Patchway Tunnels in South Gloucestershire to accommodate the electrification equipment that will power the new fleet of electric trains.
The Severn Tunnel reopened to rail passengers on Saturday, 22 October following the completion of the work, which will see electric trains on lines in South Wales.
