Looking very much like a Class 37 from the mid 1960s, but sounding very different by virtue of its six cylinder Ruston engine, D6836 (37905) passes Crownthorpe on 2 April 2016 with the 09:40 Dereham to Wymondham service, during the Mid Norfolk Railway's Diesel Gala. Prototype HST power car 41001 is on the rear of the train.
