Siemens Nexas

The Siemens Nexas (known colloquially as the "Siemens") comprises 72 triple car electrical multiple unit trains built by Siemens Mobility (was Siemens Transportation Systems) for the suburban railway network of Melbourne, Australia, from 2002-2005. The design of the trains was based on the Siemens Modular Metro (Mo.Mo) concept built in Austria. Introduced to service in 2003, the trains are some of the newest in the city's suburban fleet, however the Victorian State Government has recently ordered more of the previously delivered Alstom X'Trapolis 100 trains.
