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.[3][4] The base order was signed on May 31, 2013 for 10 locomotives with an option for additional 10, [5] which has since been exercised.[6] Additional orders were exercised as funding become 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.[7][8], 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[9], and had its first mainline run on June 10, 2017.
