The class 65 steam locomotives were passenger train tank locomotives of the German Federal Railroad (DB) . The locomotives were developed as part of the DB's new building program and were intended for suburban and light rail traffic in metropolitan areas . There they should replace the 78 and 93.5 series .
history
The Krauss-Maffei company initially supplied 13 machines in 1951 and five more from 1955 to 1956. The first machine, road number 65 007, was taken out of service in 1966.
The locomotives were assigned to the Bahnbetriebswerke (Bw) Darmstadt (7), Düsseldorf (3), Remscheid-Lennep (2) and Letmathe (1). Between Dusseldorf and Essen , they even drove in advance of the S-Bahn at the Essen depot (5). The locomotives of this series also transported freight trains between Limburg / Lahn and Wiesbaden and around Darmstadt. They were later stationed in Dillenburg , most recently in Aschaffenburg and Limburg.
The locomotives of the 65 series turned out to be extremely reliable machines after initial problems, but they could not be used universally because they only had a short range and could therefore only be used in local freight transport.
While the boiler performance was convincing, the running properties were initially unsatisfactory, at the Aw Jülich the drives of the first series were improved at the manufacturer's expense. In 1952 the locomotives were shut down due to bulges on the dome collars and only started up again in 1953 after a reinforcement ring had been riveted into the steam dome. The 65 018 was the last of its series to be parked at the Aschaffenburg depot in 1972 . It will be kept operational at the Stoom Stichting Nederland in the Netherlands after it was handed over to the German Steam Locomotive Museum (DDM) in 1981 .
Constructive features
All vehicles received a welded high-performance boiler. The company numbers 65 001 - 65 013 were equipped with a surface preheater. The numbers 65 014 - 65 018 received a mixer preheater. Road numbers 65 012 to 65 018 were equipped for push-pull train operations from 1955 to 1956. The last five of the series were on the Düsseldorf – Kettwig – Essen route . So that the stoker had a better view of the route, the push-pull locomotives were always coupled to the train with the boiler.
These two-cylinder superheated steam machines were available in three different versions on the Bundesbahn.
In the machines that were subsequently delivered, the storage containers were no longer welded to the driver's cab due to cracks. The ventilation attachment on the driver's cab was integrated into the roof. The cab doors were no longer straight, but drawn in like the rest of the cab in the upper area.
The 65 018 received a special light-running engine, later all machines received lighter piston rods and cross heads.
