EMD F125 "Spirit" Diesel-Electric Passenger Locomotive
The EMD F125 Spirit is a four-axle passenger diesel locomotive manufactured by EMD for the North American market. It is powered by a Caterpillar C175-20 V20 diesel engine rated at 4,700 hp (3,500 kW). The locomotive is capable of traveling at a maximum in-service speed of 125 mph (201 km/h) pulling consists of up to 10 cars. It is EMD's first new passenger locomotive since the EMD DE30AC and DM30AC, and EMD's first domestic passenger locomotive in 15 years.

Features of the F125 include EPA Tier 4 emissions compliance (with exhaust after-treatment), AC traction systems, extended-range blend and dynamic brakes with HEP regeneration capabilities, advanced crash energy management (CEM) technology, and a streamlined body design, designed by Vossloh Rail Vehicles of Spain.[2] The locomotive is equipped with a Nathan AirChime K2 horn placed on top of the locomotive (as opposed to the usual placement under the locomotive for other rolling stock).

Operators
The Los Angeles commuter rail agency Metrolink is the launch customer for the EMD F125, with an order of 40 total. The cost of the base order of 10 units with an option of additional 10 was estimated at $150 million, with delivery commencing in 2016. The base order was signed on May 31, 2013 for 10 locomotives with an option for additional 10,  which has since been exercised. Additional orders were exercised as funding became available. They will replace the EMD F59PH and EMD F59PHI.

The first locomotive, SCAX 903, began testing in the first quarter of 2016. The bulk of the order was expected to be delivered by April 2017, but as of June 2017, 13 locomotives have been delivered. The first one delivered, SCAX 905, was unveiled on July 18, 2016 at Los Angeles Union Station during a special event, and had its first mainline run on June 10, 2017.
