The Type DT2 is a two-car electric multiple unit train built for the Hamburg U-Bahn. The prototypes were introduced in 1960 and with almost 200 units the DT2 was the most common train type of the Hamburg subway system, especially U2 and U3 lines, until the 1990s.[2]
Description
The body was created in lightweight steel construction, licensed by the American Budd Company, whereby the mass of the vehicles could be reduced compared with the DT1. A DT2 also have a lower power consumption compared to a DT1. The DT2 trains are all-electric cars and therefore cannot be coupled with a DT1 or a DT3.
Refurbishment
From the 1980s until the early 1990s, the younger DT2s became refurbished. They received a new front (with one window instead of three) because the old ones were susceptible to rust. Because of the refurbishment, the units could be used for another 20 years. The rebuilt units were called DT2-E. The unrefurbished older units were retired until 2002.
Operation
Until 2004, the DT2s were mostly used on the U2 and U3 line. Most of the units were retired until 2005. After 2004, the last 15 units got preserved but they were used for special service during the 2006 FIFA World Cup. The preservation of the last units ended in 2008, then they received a small technical refurbishment to serve the U1 line during the peak hours. In the first half of 2009, the DT2s were used again on U2 and U3 line due to construction works on the U2 line.
The DT2 trains haven't got station announcements and CCTV cameras in the interior, which should be installed in each subway car according to statements of the Hamburger Hochbahn AG.[3] After the first of many announcements of the retirement of the DT2s in 1988, they had their last service on 27 November 2015.
