Derailed train at Barry disrupts south Wales services
Train services across south east Wales have been disrupted after a train left the tracks at Barry in the Vale of Glamorgan.
The incident involved a freight train at about 02:30 BST on Thursday morning.
Arriva Trains Wales said trains are unable to run in either direction and replacement bus services are in place between Barry and Bridgend.
Severe delays are also expected on services between Cardiff, Pontypridd and Rhymney, and from Merthyr Tydfil.
A Network Rail spokesman said the back two wagons of the train had derailed bringing it to a standstill at Porthkerry and causing damage to the track.
Delays are expected to last all day as the line remains blocked.
