An Einheitslok from the Third Reich era, this was probably an experiment, although at least one of the six engines lasted until 1956.
Note the small cylinder volume, very high boiler pressure and relatively high superheat percentage. Also, the bi-directional lok had a widely spread wheelbase for its overall size.

These were streamlined tanks for the Lubeck-Buchner Eisenbahn (LBE) that were rated at 120 km/h (75 mph) pulling (or pushing - they were bi-directional sets) trains of two double-decker coaches. At those speeds, the locomotives rode well on their Bissel carrying trucks. Painted gray and completely shrouded in a tall narrow casing, the pair soon earned the nickname of Mickey Mouse,
003, which arrived in 1937, was capable of still higher speeds according to Lindecke; see Locobase 12576.
World War II put an end to such high-speed service and the first two were mothballed in 1942. After the war, East Germany's Deutsche Reichsbahn (DR) placed 002 & 003 in commuter service in the Berlin suburbs where they ran into the 1960s.

Locobase offers what little he can find out about the three high-speed tank engines of the mid-1930s in Locobase 5742, where he discusses the first two of the class in 1935.
Christian Lindecke's comment that the 003 was capable of still higher speeds is borne out by the larger boiler. Unlike the first two gray engines, the 003 was painted black but hauled the same set of double-decker coaches.
