There was a major disruption on the railway lines between Filton Abbey Wood and Patchway today.
GWR tweeted at 13:30 saying that the line from Bristol Temple Meads to Cardiff Central was closed due to a fault in the signalling system.
The line reopened as normal at 15:00 but disruption is expected to continue, with services cancelled, delayed, or diverted.
Following a fault with the signalling system earlier today between Filton Abbey Wood and Patchway the line towards Cardiff Central has now reopened. Apologies for the delays this caused.
