With the CSX merger officially completed on Aug. 31st 1987, the new railroads large roster of GP40-2's required a uniform numbering system. The CSX master renumbering program slotted spots #6001-6392 for GP40-2's. The B&O's second order of GP40-2's, originally delivered in 1975, would fill slots #6084-6145. The GP40-2 proved to be one of CSX's most versatile locomotives on their roster, and could be found on nearly any type of train running across the system.

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.
