RAIL passengers are being warned of delays of up to 30 minutes on Great Western Railway services from south Wales to London this morning.

The warning follows a fault in the signalling system between Bristol Parkway and Patchway.

Though all lines have now reopened, and services are returning to normal, delays are predicted until at least 10am.

Travellers are reporting that trains to Bristol are currently "jam-packed", with many having to stand in the aisles.

There are also currently delays of up to 20 minutes and some cancellations on GWR services between Bristol Parkway and Severn Tunnel Junction, and knock-on delays further west.
