As part of its refurbishment, the unit underwent extensive maintenance and an overhaul that included the installation of two new engines, and restoration of the interior and seating upholster.
Railway enthusiasts affectionately nicknamed Class 121 diesel multiple units as “bubble cars”, with 16 being built by Pressed Steel at Linwood in Scotland, and are similar to the Class 122 units built by Gloucester Railway Carriage and Wagon Co.
Wensleydale's Class 121 No.55032 joined the railway's heritage diesel fleet in 2015, and in 2021 it received the Railcar of the Year Award from the Railcar Association in 2021.
The Class 121 will operate services between Leeming Bar and Scruton and on selected trips between Leeming Bar and Leyburn.
