The German DRG Class 95 are ten-coupled tank locomotives with a 2-10-2 wheel arrangement, which were procured by the Deutsche Reichsbahn (also referred to later as the Deutsche Reichsbahn-Gesellschaft or DRG) in 1922 for hauling heavy goods trains on steep main lines.

The first ten locomotives built in 1922 were ordered as T 20 Magdeburg 9201–9210, and because they were at first intended to be grouped into Class 77, were supplied as numbers 77 001 to 77 010.

Their areas of operations included the Sonneberg–Probstzella line, the Spessart ramp, the Franconian Forest Railway, the Geislingen ramp (Geislinger Steige), the Schiefe Ebene and the Rübeland Railway, where they earned their nickname Bergkönigin ('mountain queen').

Their very high adhesive weight of 95.3 tonnes (93.8 long tons; 105.1 short tons) enabled them to climb inclines of up to 70‰ (7%) without needing a rack, and their Riggenbach counter-pressure brake ensured that they could slow down with heavy loads while going downhill.

Of the 45 examples owned by the Reichsbahn, the Deutsche Bundesbahn took over 14 that, towards the end, were stationed in Aschaffenburg and used as pusher locomotives on the Spessart ramp.
