Baureihe 23
The locomotives of the Baureihe 23 were passenger train locomotives of the Deutsche Bundesbahn and were intended as a replacement for the locomotives of the Prussian class P8. Since 1950, 105 copies of the newly designed series have been built. This locomotive series was the last to be built for the DB, to be precise, the 23 105 is the last DB steam locomotive built (1959).
Originated from two machines (BR 23 alt) built in 1940, which were not further developed during the war, this post-war machine is equipped with all kinds of modern gadgets. The locomotives had welded frames, boilers and tenders, unlike the riveted frames and boilers of the older DB machines. The 23-ers also got a central greasing press and a so-called Heizdampf regulator.
Until 23 052 the locomotives were fitted with plain bearings, the later locomotives got roller bearings (including coupling and connecting rod bearings). Furthermore, all locomotives were equipped with the so-called wendezug-steuerung, whereby the machines could run in pull-push combinations.

The VSM owns two locomotives from the Baureihe 23. The 23 071 and the 23 076, or the ‘71’ and the ‘76’ for short.
23 076 was the first 23-er to join the VSM in 1976, followed by 23 071 in 1978. 23 076 was put aside after a few years of service awaiting its overhaul. She has stood still for more than 20 years. In the summer of 2007, the machine was completely ‘reborn’ from the overhaul to return to its mileage at the VSM.
