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.

July and August


Oxford – 22 to 30 July 2017

Network Rail will be carrying out improvements between Banbury, Oxford and Didcot Parkway, reducing the potential for delays in the area.

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.
