Siemens Nexas

The Siemens Nexas are a class of electric multiple units manufactured by Siemens Transportation Systems for the suburban railway network of Melbourne, Australia between 2002 and 2005. The design of the trains was based on the Siemens Modular Metro.

History

In March 2000 M>Train ordered 62 Siemens Nexas trains to fulfill a franchise commitment to replace its fleet of Hitachi trains.

The original order was for 62 3-car sets, with an option for an additional ten 3-car sets. In December 2002 just before the first was delivered, National Express handed the M>Train franchise back to the Government of Victoria, thus the first Siemens Nexas' were delivered to the government. All passed to Connex Melbourne in April 2004. The option for ten additional trains was exercised in August 2005, with the last of these delivered in January 2006.

Siemens Rail Services was contracted to provide maintenance of the trains for a period of 15 years (subject to refranchising) at Newport Workshops. With the refranchising of the network to Metro Trains Melbourne in 2009, this maintenance arrangement was retained for an initial three-year period.
