Metrolink's first EMD F125, #903

The EMD F125, also named Spirit, is a diesel-electric passenger locomotive currently being built by Electro-Motive Diesel, a subsidary of Caterpillar Industries. The locomotive will be compliant to EPA Tier 4 regulations, have AC traction systems, advanced crash protection, and a streamlined body which meets Amtrak's loading gauge. The locomotive's maximum speed is 125mph (200km/h). Unlike other EMD products, which use EMD's own 2-stroke diesel engines, this locomotive will be powered by a 20 cylinder Caterpillar C175 high speed, four-stroke diesel engine.

Los Angeles' Metrolink is the launch customer for this locomotive. Delivery is expected in 2015.
