The Type DT1 is a two-car electric multiple unit (EMU) train type operated by the Hamburger Hochbahn AG (HHA) on the Hamburg U-Bahn until 1991. They were the first new U-Bahn trains since the 1930s.
Technical specifications
The units were formed as two-car sets. The car bodies are made out of welded steel. Each bogie is fitted with two axle-hung motors.[3]
Interior
The first units were fitted with transverse seating. Subsequent units were fitted with a mix of longitudinal and transverse seats.[3] Each car has three 2-leaf-doors on each side.

History
The trains were originally numbered 9431/9432 to 9529/9530, and were renumbered to 9000/9001 to 9098/9099 in 1960.[3] Their livery was changed between 1969 and 1971 to unify the look of the Hochbahn trains, with the DT1 trains receiving a 2-tone grey livery with orangered doors and cab ends, similar to the Type DT2 and Type DT3. DT1 trains were restricted to peak-hour services since 1971. The sets still in service in the 1980s were renumbered to 501 to 544. Withdrawals began in 1987 and were finished in 1991.[3]
Preserved examples
Set 516 was rebuilt into the Hanseat party train in 1997 to 2000.[3] The rebuilding included retrofitting of a bar and toilet into one car, and the restoration of the other car into its original state. A gangway connection was also installed, and the train was reliveried into its original red/cream livery scheme, as well as renumbered to its original number 9030/9031.[3]
