This list is far from comprehensive, and what constitutes an 'unusual' locomotive is very subjective. At present I think that H02 1001 is probably top of the unusual list with a boiler pressure of 120 atmospheres (almost 1700 psi...!).

Class or number Origins Type Built

Bavarian AAI J.A. Maffei 4-cylinder compound 4-2-2 with a booster single axle between the front bogie and the driving wheels. 1895
Rebuilt in 1908 into a 4-4-0, 36 861

Caution: 350kb image Schwartzkopff-Löffler High Pressure Locomotive
Boiler pressure - 120 atmospheres - about 1763 psi 3-cylinder 4-6-2 1930

03 154 Einheitslok
(DRG Standard design) 'Lightweight' 2-cylinder 4-6-2 with add-on experimental streamlined casing
'Production' streamlining looked very much like that of 19 1001 (below) 1930

(DRG Standard design) Streamlined 3-cylinder 4-6-4 originally built with a cab-forward configuration. 1934

Bavarian S²/₆ J.A. Maffei 4-4-4 - essentially a research loco
It was fast (154km/h), but too light to be useful in regular service 1906

H17 206 DRG rebuilt 17² with high pressure boiler - 60 atmospheres - about 881 psi 3-cylinder 4-6-0 1933

T18 1001 DRG and Krupp joint design Steam turbine powered 4-6-2
Turbines proved to be too expensive to maintain 1923

T18 1002 DRG and J.A. Maffei joint design Steam turbine powered 4-6-2
Turbines proved to be too expensive to maintain 1926

19 1001 DRG experimental An unusual streamlined 2-8-2 with 2 inclined cylinders per powered axle - 8 cylinders in total 1941

38 3255 DRG rebuilt 38^10-40 2-cylinder 4-6-0 with supplementary steam turbine powered 2-4-4 tender 1927

50⁴⁰ DB rebuild of a standard 50 with a Franco-Crosti boiler 2-cylinder 2-10-0 1959

61 001 Einheitslok
(DRG Standard design) Streamlined 2-cylinder 4-6-4 designed to pull the Henschel-Wegmann train. 1935

61 002 Einheitslok
(DRG Standard design) Streamlined 3-cylinder 4-6-6 designed to pull the Henschel-Wegmann train. 1937
Rebuilt by the DR in 1961 in to 18 201

99¹⁶ Saxon I M 1000mm (39 ¹/₃") gauge 0-4-4-0 Fairlie tram locomotive.
This one has had it's original overall roof removed. 1902
99⁶² Württemberg Tss 4 750mm (29 ¹/₂") gauge 0-8-0 with Klose Lenkachsen.
It is not at all clear to look at exactly how this is supposed to work. It was intended to assist in negotiation of tight curves. 1894
