To meet EPAs emissions standards
The Siemens Charger is a diesel-electric locomotive designed by Siemens Mobility, intended to serve the North-American diesel locomotive market.
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 take effect in 2015. Top speed in service as per PRIIA specifications is 125 mph (201 km/h).[5] 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.
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. Included in the $225 million are options for an additional 75 corridor-configured locomotives and 150 locomotives configured for long distance service,[ 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.
All Aboard Florida purchased 10 locomotives with the option to procure an additional 10 further down the line. The locomotives will be used in pairs, bookending 4 passenger cars (expandable to 7) on a new rail system between Miami and Orlando.
