69-712: The Siemens Desiro ( / ˈ d ɛ z i r oʊ / , / d ɛ ˈ z iː r oʊ / , German pronunciation: [ˈdɛziʁoː] ) is a family of diesel or electric multiple unit passenger trains developed by Siemens Mobility , a division of the German Siemens AG conglomerate. The main variants are the Desiro Classic, Desiro ML, Desiro UK and the later Desiro City, Desiro HC and Desiro RUS. The trains are mostly used for commuter and regional services, and their rapid acceleration makes them suitable for services with short distances between stations. The design

The SVT 877 Fliegender Hamburger DMU, introduced in 1933, made the run from Berlin to Hamburg in an astonishing 138 minutes, and its derivative SVT 137 broke the land speed record in 1936. After World War 2, the VT 11.5 DMU was the flagship of the glamorous Trans Europ Express . Since 1968, DB has designated DMUs with class numbers beginning in 6. While DB and regional transport authorities generally prefer electric power for commuter rail, many local and rural lines remain un-electrified, and DMUs are invaluable in providing services to those areas. DMUs in service as of 2021 include
207-561: A 35 km (22 mi) railway line. Twelve married pairs were delivered in August 2006 to the operator North County Transit District (NCTD). Service began on March 9, 2008, serving fifteen stations along the 22 mile right of way. Mountain Rail, one of two competing coalitions bidding on a large portion of FasTracks in Denver , appeared to be proposing a Siemens Desiro ML derived vehicle that
