History

The Los Angeles commuter rail agency Metrolink was the launch customer for the EMD F125, with an order for 40. 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 replaced the EMD F59PH and F59PHI. The first locomotive began testing in the first quarter of 2016 and was shown to the public on July 18, 2016 at

As of 2022, all F125 locomotives had been delivered to Metrolink and placed in service. The F125 competes with other Tier 4 compliant locomotives, such as the
