Engineering work is taking place between Didcot Parkway and Chippenham / Bristol Parkway, closing lines overnight from Monday evening until Friday morning.

As a result:

  • The 22:48 London Paddington to Swansea service will be diverted between Swindon and Bristol Parkway, extending journey times from Bristol Parkway onwards.
  • The 23:32 London Paddington to Cardiff Central service will be diverted between Reading and Bath Spa, not calling at Didcot Parkway, Swindon or Chippenham. A replacement bus will run from Reading to Swindon and Chippenham, with a replacement bus running from Didcot to Swindon connecting with this bus. Additionally, a replacement bus will run from Swindon to Bristol Temple Meads, calling at Chippenham and Bath Spa. Customers travelling to Didcot Parkway should use the 23:15 London Paddington to Oxford service, which will additionally call at Didcot Parkway.
