Planned engineering

Electrification, and the roll-out of our new trains, does impact our services from time-to-time. We work closely with our partners to keep you up to date.

October and November


New GWR electric trains will be running through Reading soon. To prepare for this, Network Rail need to test the overhead wires in the area.

Bristol Parkway and Cardiff

Network Rail is carrying out work to electrify the railway through tunnels between Bristol Parkway and Swindon, and lower the track in the Cardiff area ahead of installing overhead wires by late 2018. A new platform is also being built at Bristol Parkway.

Network Rail will be working on the overhead wires and other infrastructure to deliver two key projects, which mean we need to make changes to our train services.
