The WSR Diesel Multiple Unit (DMU) is comprised of 3 class 115 vehicles. Two DMBS vehicles with a modified TC in the centre. The TC is modified to include a small buffet area for serving refreshments. The DMU is in operation on the railway on the majority of running days, often on the quieter diagrams, delivering a much needed support service to the popular steam locomotive hauled timetables.

A group of volunteers, known as the DMU Spanner Bashers, would like to repair the old door handles, locks and striker plates to comply with the railway's Safety Management System and ensure that the unit is safe to run. This fund is to purchase the necessary parts. All the labour will be supplied by the volunteers.

The DMU is lighter, cheaper and easier to operate than full steam or diesel hauled trains and will be central to any new running on the WSR. It's very different to the modern units and a heritage item in its own right.

It's essential that the repairs are carried out as soon as possible, to help with the future planning for the railway.
