The Type DT5 is an electric multiple unit (EMU) train type operated by the Hamburger Hochbahn AG on the Hamburg U-Bahn system. It is the first type of rolling stock on the Hamburg U-Bahn that has air conditioning and gangways between the individual cars.[1]

Formation

Every DT5 train consists of three permanently-coupled cars. The cars are connected with gangways, allowing passengers to walk into the adjacent cars.[1] Up to three units can be coupled together.[2]

Interior

The interior consists of red upholstered seating, and spaces for wheelchairs[1] and prams.[3] The trains have displays which show the names of the next four stations, and CCTV cameras.[3] The interior is air conditioned.[2]

Technical specifications

The train is built to an articulated design, with the two end cars only having one bogie, while the center car has two bogies.[1] The car bodies are made out of stainless steel, and the trains are powered by three-phase motors.[1] In order to save weight, the DT5 trains use aluminium brake discs, which make a loud squealing sound while braking.[4]

History

A European-Union - wide tender for the construction of the DT5 trains began in 2005.[5] Siemens, Stadler, Rotem and a consortium of Alstom and Bombardier bid for the contract.[1] The trains were ordered in December 2006 from the consortium of Alstom and Bombardier at a cost of 240 million Euros.[1] The first unit was delivered to the Barmbek depot on December 1, 2011.[6] Further DT5 trains were ordered in 2016,[7] 2018[8] and 2019[9] bringing the total number of ordered trains to 163, of which 163[10] have already been delivered.
