Network Rail has completed work to clear the Rhymney line near Bargoed after a train was derailed yesterday morning.
The line was handed back at 3.30pm today with a 10mph speed restriction in place following work to clear trees and debris from the landslip that caused the derailment.
The first service that is likely to use the track will be the 3.02pm service from Penarth to Rhymney due at approximately 4.13pm.
A Network Rail spokesperson said: “We have cleared the trees and debris from beneath the train and re-railing was completed at 12.24pm.
“The train was moved from site at 12.45pm and the crane used to lift it back onto the rails has since departed from the site and the track is now fit for traffic.
“We are working closely with Arriva Trains Wales to achieve a resumption of scheduled train services as soon as possible.”
The 6.10am Rhymney to Barry Island service, the first of the day, was derailed just before 6.30am on Wednesday after a landslip caused by flooding caused by the recent snow.
There were three reported injuries. Two people sustained bumps to the head and one person suffered shock. All injured persons were treated on the scene by ambulance crews and released.
