During the late 1980’s, CSX Transportation modified many of their GP40-2’s into “slug mothers” that powered RDMT (CSX term, short for Road-Mate) road slugs. The “slug” is a term used for (in most cases) a secondary locomotive that has a removed/deactivated engine but kept it’s traction motors. The “mother” unit at slow speeds can produce enough power to provide electric current to other traction motors using the same amount of fuel consumption. The ‘” mother” and “slug” combination can provide the power of two locomotives using a single diesel powered unit. CSX liked the results, and modified many older GP30 and GP35’s into road slugs, retaining their cab controls so that they could still be operated in lead position, but without the noise from the prime mover.

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 engines 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.
