Engineering work is taking place between Swindon and Bristol Parkway, closing lines early in the morning from Tuesday to Friday.
As a result, the 04:53 Bristol Temple Meads to London Paddington service will start from Bristol Parkway earlier than usual at 04:36, then running to Bristol Temple Meads. From Bristol Temple Meads onwards, the train will run to usual timings.
