"The engine, rated at 4,400 hp (3,281 kW) will be delivered to the Siemens manufacturing facility in Sacramento, Calif., where it will be installed into a Charger® locomotive. The Charger—a diesel-electric passenger locomotive—will be put into service for a five-state, 35-unit initial order with the departments of transportation of Illinois, California, Michigan, Missouri and Washington. The Charger locomotives will also power the trainsets for All Aboard Florida."
