Description

GE Transportation Systems "GENESIS" Series 1 passenger locomotives photographed in Washington Union Station on 18 September 2014.
These have an engine output of 4,250 hp (3,170 kW) at 1047 rpm, or 3,550 hp (2,650 kW) when running in HEP (Head-End Power supplied to the train coaches) mode (900 rpm) with a 0 kW HEP load. Traction horsepower in HEP mode decreases to a bare minimum of 2,525 horsepower (1,880 kW) when providing the full 800 kW HEP load to the train. The P42DC has a maximum speed of 110 mph (177 km/h),
The Genesis series are unique among current North American diesel-electric locomotives because of their low height. This height restriction allowed the locomotive to travel easily through low-profile tunnels in the Northeast Corridor. The Genesis series is lower than even the previous-generation F40PH by 14 inches (356 mm), and is the only Amtrak diesel locomotive that meets the clearance requirements on every Amtrak route. A majority of Amtrak's trains are powered by at least one Genesis unit.
The bogie trucks of Genesis locomotives were made by Krupp Verkehrstechnik, which has since been absorbed by Siemens Mobility; the trucks on the newest Genesis locomotives carry the Siemens name.
