The GE Dash 8-32BWH, also known as the P32-8BWH, B32-8WH, or P32-8, is a passenger train locomotive used by Amtrak, based on GE's Dash 8 series of freight train locomotives. Built in 1991, they were the first locomotives purchased to replace the EMD F40PH.
Twenty of these locomotives were delivered to Amtrak in 1991, numbered 500 through 519. They were nicknamed " Pepsi Cans" by many railfans, due to being delivered in a wide-striped red, white, and blue

Design
The Dash 8-32BWH operates in a diesel-electric configuration that uses DC to power the traction motors, producing at 1047 rpm. When providing head end power to the train, the engine is speed locked to 900 rpm. Power output to the traction motors is when running in HEP mode with a 0 kW HEP load. Traction horsepower decreases to a bare minimum of when providing the maximum HEP load to the train. The Dash 8-32BWH has a 74:29 gear ratio, resulting in a maximum operating speed of in passenger operation.History
Twenty of these locomotives were delivered to Amtrak in 1991, numbered 500 through 519. They were nicknamed " Pepsi Cans" by many railfans, due to being delivered in a wide-striped red, white, and blue livery
A livery is an identifying design, such as a uniform, ornament, symbol or insignia that designates ownership or affiliation, often found on an individual or vehicle. Livery will often have elements of the heraldry relating to the individual or ...
. Since the most recent overhaul, however, the locomotives now wear the Phase V livery.
The Dash 8-32BWH has since been relegated to yard switching (mainly in Los Angeles, Oakland, Chicago, Miami, and the Auto Train terminals), maintenance of way service, and transfer service, displaced by the newer and more powerful GE Genesis and Siemens Charger. However, the Dash–8s occasionally substitute for the Genesis and Charger units if necessary. The Los Angeles-based units see frequent use on the '' Coast Starlight'' and '' Pacific Surfliner'', and many are also frequently used on Amtrak's Cascades service. The East Coast-based units back up the routes in and out of Washington DC, sometimes running on the ''Cardinal'', ''Crescent'', ''Silver ''Service'', or the Virginia ''Northeast Regional'' train.
Two of the locomotives, 501 and 502, were sold to the California Department of Transportation. The locomotives were renumbered 2051 and 2052, and received the Amtrak California paint scheme. They are used on the '' San Joaquin'' and '' Capitol Corridor'' trains.
