Engineering work is taking place between Cardiff Central and Newport, closing some lines.
Great Western Railway:
As a result of capacity constraints between Cardiff Central and Newport, most trains between Cardiff Central and Taunton will run between Bristol Temple Meads and Taunton only (the 10:50 Cardiff Central to Taunton will still run, but will be retimed slightly between Newport and Bristol Temple Meads).
Most trains between Cardiff Central and Portsmouth Harbour will additionally call at Severn Tunnel Junction, and will be retimed to run up to 20 minutes earlier than usual.
Transport for Wales:
It is not yet known how Transport for Wales will be affected by this engineering work.
