The EMD F40PH is a type of four-axle, 16-cylinder, passenger diesel locomotive manufactured by EMD between 1975-1992 (including its variants). Morrison-Knudsen also built several variants between 1991 to 2000, while the main model was built between 1976 to 1988. Several commuter railroads currently use F40PH locomotives, though the model was originally intended as a specialty locomotive for Amtrak.

Many have since been scrapped, rebuilt, and/or retired. Amtrak no longer utilizes any of their original F40PH units in active service, however, many shells of former units still remain as NPCU (Non-powered Control Unit) cab/bagagge cars ("cabbage" cars) in head-end service.

Some are preserved in various museums, while others are undergoing restoration.

History Edit

However after many years of service the locomotives were retired and replaced with GE Genesis Series locomotives like the P40DC and P42DC beginning in 1993. Along with Amtrak, several other railroads purchased the F40PH including VIA Rail, Metra, Caltrain, MBTA, Coaster, Metrolink, GO Transit, and Music City Star and CSX.
