A Class 148 at Sheffield Midland in the late 1960s. Later known as a Class 114 DTC(L), this vehicle was classified as Class 148 at the time this slide was taken - believed to be late 1960s due to the presence of green liveried vehicles. Unusually, it lacks the yellow line above the first class accommodation, although window stickers are visible - it is unlikely to have been declassified by this early stage.
