The two new class 66 locomotives were passenger train tank locomotives of the Deutsche Bundesbahn .
The 66 series was intended for express freight train service and passenger train service on the main and branch lines of the Deutsche Bundesbahn. A top speed of 100 km / h and a wheel set weight of only 15 t offered the best conditions for this. It was supposed to replace the regional railway types of the 38.10 , 78 and 93 series . Due to the increasing competition from diesel locomotives , the two examples of the 66 series remained individual pieces, although they met all expectations and were considered a very successful construction. The class 66 was the penultimate steam locomotive series that was built as part of the DB new build program.
The vehicles were equipped with a welded high-performance boiler with a combustion chamber , roller bearings, a mixer preheater and a welded sheet metal frame. Since great emphasis was placed on the working conditions of the engine driver and stoker , the 66 series had a completely enclosed driver's cab , skylight windows, underfloor heating and padded seats with backrests. From autumn 1957, both locomotives were equipped with facilities for push-pull operation.
The locomotive with the road number 66 001 was retired in 1967 due to an engine failure and parked in Giessen, the second example was retired in 1968.
Whereabouts
The locomotive 66 002 was bought by the German Society for Railway History after its retirement and is currently housed in the Bochum Railway Museum.
