BUT - Equipment fitted to Diesel Multiple Units
50001-50394
Index of Initial Equipment Fitted to Railcars (From the BUT Spare Parts Catalogue: AEC, SCG. Ltd & Leyland sections).
Note: in the case of the Class 114s below this shows the replacement Albion engines rather than the original Leyland 680s fitted when delivered. For Met-Camms 50270-9 and 50280-9 they are shows as having AEC engines. It's believed they were originally ordered as such, then Rolls-Royce engines were specified before delivery.
Class 105 vehicles 50371 and 50372 were built with Leylands but soon converted to AEC engines as listed below.
