Engineering work is taking place between Slough and Twyford, closing some lines all day.
As a result, Great Western Railway services running from London Paddington to Newbury / Bedwyn, Cheltenham Spa, Bristol Temple Meads / Swansea and also to Penzance will be amended, and will depart London Paddington up to 8 minutes earlier than usual.
