Siemens Charger
The Siemens Charger is a diesel-electric locomotive designed by Siemens Mobility, intended to serve the North American diesel locomotive market.
Design
The Charger is powered by a 4,400 hp (3,300 kW) Cummins 16 cylinder QSK95 4-stroke high speed diesel engine, which is designed to meet EPA Tier IV emissions standards that took effect in 2015. Top speed in service as per PRIIA specifications is 125 mph (201 km/h). The overall design and layout of the locomotive is shared heavily with its electric counterparts in Europe (the Vectron) and the United States (the ACS-64), diesel equipment aside. Power to the AC traction motors is delivered from the main alternator via four IGBT inverters (one per motor), with head-end power being supplied by a static inverter off of the main prime mover. The locomotive also features dynamic braking with regenerative capability, allowing the locomotive to divert power generated by dynamic braking away from the resistor grids to HEP and on board locomotive auxiliary power demands.

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.
