The locomotives of the T series 18.10 were steam turbine-driven steam locomotives of the Deutsche Reichsbahn of the wheel arrangement 2'C1 '. The two locomotives of the T 18.10 series were built between 1923 and 1926 to test the applicability of a full steam expansion in turbines in locomotive construction. An improvement in efficiency was expected, as well as safe and shock-free start-up and protection of the superstructure , as the masses moving back and forth were greatly reduced.
T 18 1001
The T 18 1001 was built by Krupp in 1924 and had a six-stage Krupp- Zoelly type steam turbine installed above the front bogie, transverse to the direction of travel . The power was transmitted to the coupling wheels via a gear transmission and a jackshaft . The locomotive had a second, smaller, three-stage turbine for reversing. In fact, the test drives turned out to be great savings compared to conventional locomotives.
After the test drives, the locomotive was rebuilt: the turbine for reversing was removed and replaced by a starting and shunting turbine working on a reversing gear .
The vehicle was in service until 1940 and was bombed two times during the war. She was in the depot Hamm home.
The locomotive was equipped with a condensation tender coupled the type 2'2 'T19,5.
T 18 1002
The T 18 1002 was completely redesigned and built by Maffei in 1926 . The condensers were attached lengthways on both sides under the circulations and a Ljungström turbine was used. The forward and reverse turbines had a common housing and drove the jackshaft via a double countershaft. In contrast to the first locomotive, however, no significant savings in consumption were achieved. From 1926 to 1943 it was based in the Munich Hbf depot. It was used sporadically as an express train locomotive until 1943 and was retired after being bombed. The locomotive's boiler was mounted on a series 52 frame and served until 1964 in the Ingolstadt and Munich repair shops as a testing system for boiler safety valves .
The locomotive was coupled to a type 2'2 'T24 condensing tender.
