Engineering work is taking place between Cardiff Central and Severn Tunnel Junction, closing some lines.

As a result, most services running to, from or via Cardiff Central will be retimed to run earlier or later than usual. Some services will be amended to start from different stations than usual, or be cancelled throughout. Some services will make additional stops.

In addition to train services between Patchway and Filton Abbey Wood, buses will run roughly hourly between 09:45 and 20:00 in both directions between Patchway and Filton Abbey Wood.
