SIEMENS confirmed on April 18 that the first SC-44 Charger diesel-electric passenger locomotives for California Department of Transportation (Caltrans) will begin revenue testing on the Sacramento - Oakland - San Jose Capitol Corridor before the end of the month.

One of the first locomotives went on public display at the California State Railroad Museum in Sacramento on April 18-19, coinciding with the California Passenger Rail Summit, which is being held in the city.

California will receive 22 of the 4.4MW locomotives for use on Amtrak's Capitol Corridor and Pacific Surfliner services.

The four-axle ac traction Charger is the first locomotive to be equipped with Cummins’ QSK 95 power unit. The 95-litre 16-cylinder engine is equipped with Cummins’ Modular Common Rail Fuel System (MCRS) with quad-turbocharging. The QSK95 also features Selective Catalytic Reduction (SCR) exhaust aftertreatment, ensuring compliance with US Environmental Protection Agency (EPA) Tier 4 emissions standards.
