A south Wales rail line has reopened after being forced to close after a freight train derailed between Barry and Rhoose on Monday night.
The train was carrying coal to a nearby power station
Replacement buses were put on for passengers on Tuesday after the incident on the Vale of Glamorgan line.
The line from Barry to Bridgend was closed while a detailed examination of the train and track took place.
Transport Police said two carriages carrying coal came off the rails at about 2200 BST on Monday.
A Network Rail spokesperson said: "We can confirm that a derailment occurred on the Vale of Glamorgan line, close to Porthkerry Tunnel, as a EW&S freight train carried coal to Aberthaw Power Station.
The line was reopened to passenger trains earlier this year
"The rear two wagons of the train derailed. No injuries resulted from the incident.
"A full investigation is being carried out into the causes and a shuttle service will be operating between Bridgend and Rhoose Cardiff International Airport Stations."
Accident investigators are examining the scene and the derailed carriages will remain on the site until inspections are completed.
It is expected that the scene will be cleared by the end of Tuesday, however it is not known if there was damage to the tracks.
Passengers travelling from Rhoose had to take a bus
Arriva Trains apologised for the inconvenience and said that they were not able to say when a full service would resume, until the extent of any track damage was established.
The Vale of Glamorgan line was reopened to regular passenger services in June.
The line, which runs from Cardiff to Bridgend via Llantwit Major, was re-opened to serve Cardiff International Airport.
Around £17m was needed to pay for the service, which includes new stations at Llantwit Major and Rhoose.
