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.

August and September


London Waterloo station – 5 to 28 August 2017

This summer, fewer SWT trains will run as work starts to extend platforms. Some GWR train services to London Paddington may be busier than normal as a result.

For more information, visit the South West Trains Waterloo & South West Upgrade page.

August to November

Bristol Parkway and Cardiff – 19 August to 19 November 2017

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.

View our Autumn Upgrade 2017 information page.


Reading - 16 to 17 September

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.
