The DR class 65.10 was a quadruple coupled passenger tank locomotive of the Deutsche Reichsbahn (DR) for heavy suburban and commuter traffic.
history
To unify and modernize its locomotive parks and as a future replacement for the series 74 , 75 , 78 , 86 , 93 and 94 left the German Reichsbahn from 1950 develop several four-coupled neubaulokomotive. For passenger and freight train services, the railway administration then procured 88 vehicles of the 1'D2 'tank locomotive known as the 65.10 series from this program. VEB Leuna-Werke Walter Ulbricht ordered seven more machines of this series for its factory railways.
The production of the pre-series locomotives 1001 and 1002 took place in VEB Lokomotivbau Elektrotechnische Werke Hans Beimler Hennigsdorf (LEW, formerly AEG ), the series production in Lokomotivbau Karl Marx Babelsberg (LKM, formerly Orenstein & Koppel ).
The 65 1001 was presented to the public at the Leipzig autumn fair in 1954 as the DR's first new locomotive.
construction
The vehicles had a welded frame, a welded boiler and mixer preheater and large storage containers to carry more fuels (initially brown coal briquettes). In the 65.10 series, the two wheel sets of the rear bogie, in contrast to the 65 series of DB, were mounted in an outer frame.

The 65.10 was stationed all over the GDR in addition to the DR's northern depots, and in the 1960s it was primarily used for commuter traffic with double-decker trains, including push-pull trains. The machines 65 1009; 1015; 1017; 1025; 1026; 1034; 1058; 1063 and 1081 equipped with a push-pull train control. With the introduction of the DR series 118 this area of application disappeared. It was also used in freight train service.
The locomotive 65 1004 was the only German tank engine with a pulverized coal system Wendler equipped, which worked satisfactorily after corrections to the design. However, this conversion was reversed in 1962. From 1966 all locomotives were equipped with Giesl flat chimneys.
Whereabouts
Only because of their use as heating locomotives are three machines left today. The locomotive 65 1008, which belongs to the DB Museum , was preserved as a heating locomotive in East Saxony and is externally refurbished in the former Pasewalk depot . 65 1049 also belongs to the DB Museum and was in use at the Saxon Railway Museum in Chemnitz-Hilbersdorf until September 10, 2011 (deadline) . It has been in the historic Arnstadt depot since 2012. The locomotive 65 1057, also externally refurbished, is owned by the Berliner Eisenbahnfreunde (BEF) at the Basdorf location. The 65 1057 of the BEF is now to be refurbished to be operational again.
