PROTOTYPE AND BACKGROUND INFO:

By the early 1970s, many first generation diesels were reaching the end of their service lives. One of the most common replacement locomotives became the GP40-2. EMD began production of the 16-cylinder, turbocharged, 3000 horsepower engine in 1972. These locomotives were developed for service where higher horsepower and faster service were preferable. A major feature for the GP40-2 was the introduction of the “dash 2” modular electrical cabinet. For more than 40 years, the GP40-2 has worked main line freights, locals, switching jobs, yard service, and helper service. Many remain in service today.

The RF&P’s long history dates back to the early-mid 1800’s where it originally ran from Richmond to the Potomac River via Fredericksburg in Virginia. When they started to dieselize in 1940, they purchased a few Alco switchers. By the 1950’s, RF&P’s diesel roster was primarily EMD. Liking the performance of the EMD GP35 and GP40, they purchased seven GP40-2’s in 1972. After being absorbed into the CSX system in 1991, the GP40-2’s were patched, then repainted into the then-new CSX corporate colors. An oddity for CSX, these units stand out as being part of the few non-dynamic road units on their roster.
