Illinois Department of Transportation (IDOT) awarded Siemens a $228 million contract in 2014 to supply 32 of the 125-mph diesel-electric locomotives for use on Amtrak services in the states of Illinois, California, Michigan, Missouri and Washington. The locomotives are being assembled at the Siemens plant in Sacramento, Calif., and the first units are due to be accepted by IDOT in December.
The first options for additional units were exercised in November 2015, when the states of California, Illinois and Maryland ordered a total of 34 locomotives.
In September 2014, Florida East Coast Industries subsidiary All Aboard Florida ordered 10 Charger locomotives to operate its Brightline higher-speed passenger service from Miami to Fort Lauderdale and Orlando, which is due to be launched next year. Assembly of these locomotives is now under way at Sacramento.
The four-axle, AC-traction Charger is the first locomotive to be equipped with the Cummins QSK95 prime-mover. The 95-litre, 16 cylinder engine is rated at 4,400 hp (3.28 MW) and is equipped with Cummins’ Modular Common Rail Fuel System (MCRS) with quad-turbocharging. The QSK95 is also equipped with Selective Catalytic Reduction (SCR) exhaust aftertreatment, enabling it to meet U.S. Environmental Protection Agency (EPA) Tier 4 emissions standards.
