The two car Class 108 diesel multiple unit was purchased from the Bodmin Railway in 2018 using donations and loans from Weardale Railway Trust members. It saw some action in 2019 as back up to the single car Class 122 unit on the regular heritage services.

Since then it has been undergoing a thorough inspection and overhaul. During this inspection it was found that one of the four gearboxes needed specialist repair off site. This repair has been completed and now the gearbox is back in the depot and ready to be re-installed.

Work has continued on this and other repairs during the various phases of the Coronovirus regulations, albeit at a reduced pace. This work has been carried out under the leadership of Trust chairman, Kevin Richardson  with the assistance of Trust volunteers Nobby Clarke and Tom Hatton. They have recently been joined by Derek Ward, John Rottgart and Colin Saint.

 Amongst the tasks currently  underway are the repair and repaint of the roof boards, repairs to the headcode display boxes and cleaning and revarnishing  of the wooden window surrounds.
