A total of 20 units of this type were built, with the last units being delivered in December of 1991.
All were built specifically for Amtrak and numbered 500 through 519.
They were nicknamed "Pepsi Cans" and Hockey Sticks" by many railfans, due to being originally painted in a wide-striped red, white, and blue livery.
Since the most recent overhaul, however, the locomotives now have the current Phase V blue-silver livery with the current "wave" logo.

They were also the first locomotives that Amtrak purchased to replace the EMD F40PH before the introduction of the GE Genesis series locomotives in 1993.
Although the units have since been regulated to yard service, maintenance of way service and transfer service, they can still be seen on passenger trains.

Two of the units, Amtrak numbers #501 and #502, were sold to the California Department of Transportation. (
CDTX) In 1994.
The locomotives were renumbered #2051 and #2052, and received the Amtrak California paint scheme.
They are currently being used on the State-Supported San Joaquin and Capital Corridor trains.
