Two essential railway projects are taking place this weekend, from 1am on Saturday 11 May through to 5am on Monday 13 May.
- Trains between London Paddington and Bristol Temple Meads will be diverted and won't call at Keynsham, Oldfield Park, Bath Spa or Chippenham.
- Buses replace trains at these stations, as well as between Swindon and Westbury/Frome (via Melksham).
The same travel arrangements also apply on Sunday 23 June and Sunday 7 July.
In each case, all services are due to return to normal for the Monday morning, but please check before you travel at www.nationalrail.co.uk
