The EMD F125 Spirit is a four-axle high speed passenger diesel locomotive to be manufactured by EMD. It is powered by a Caterpillar C175-20 diesel engine rated at 4,700 hp (3,500 kW). The locomotive will be capable of traveling at a maximum in service speed of 125 mph (201 km/h) pulling consists of up to 10 cars. It will be EMD's first new passenger locomotive since the F59PHI.

Several features include EPA Tier 4 emissions compliance, AC traction systems, extended range blend and dynamic brakes with HEP regeneration capabilities, advanced crash energy management (CEM) technology, and streamlined body design.[2]

Operators[edit]

Los Angeles commuter agency Metrolink is the first to order this locomotive, purchasing 10 with an option for 10 more. Cost is estimated at $129.4 million with delivery expected to commence in 2015.[3][4] The order was signed on May 31, 2013.[5]
