The Siemens Charger is a diesel-electric locomotive designed by Siemens Mobility, intended to serve the North American diesel locomotive market. The first production unit was unveiled on March 26, 2016.[5]

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.[6] Top speed in service as per PRIIA specifications is 125 mph (201 km/h).[7] 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.[3]

Customers

Amtrak

The Illinois Department of Transportation, in conjunction with its counterparts in California, Michigan, Missouri and Washington, purchased 32 locomotives for corridor service operated by Amtrak in March 2014. Included in this $225 million order are options for an additional 75 corridor-configured locomotives and 150 locomotives configured for long distance service,[8] with the long distance locomotive being fitted with a larger 2,200 US gallons (8,300 L; 1,800 imp gal) fuel tank as opposed to the 1,800 US gallons (6,800 L; 1,500 imp gal) tank on the corridor locomotive.[7]

In November 2015, the states exercised the option to purchase 26 more locomotives. Out of 58 locomotives ordered, 20 will go to California, 8 to Washington state, 2 to Missouri, and 28 to Illinois.[9]

Maryland Area Regional Commuter

Main article: MARC Train

MARC announced in August 2015 that it is seeking $58 million to purchase eight locomotives to replace their aging electric fleet, with deliveries planned for late 2017.[10] The purchase was approved by the Maryland Board of Public Works on September 16, 2015.[11]

Northern Lights Express

Main article: Northern Lights Express

Northern Lights Express, a proposed higher-speed passenger train in Minnesota, has tabbed Charger locomotives to power the train when it opens in 2020.[12]

Brightline

Main article: Brightline

Brightline purchased ten locomotives with options for an additional 11.[9][13] The locomotives will be used in pairs, bookending five passenger cars (expandable to seven) on a new rail system between Miami and Orlando.
