The EMD GP60 followed the GP50 beginning production in late 1985.
During this era General Electric had already taken over first place in
the locomotive manufacturing market and EMD was scrambling to catch up.
Its GP60 was unable to create any serious inroads into GE's market share although it did sell marginally well with nearly 400 units produced. The GP60 featured General Motors' 16-cylinder model 710G3A prime mover which allowed it to produce a very respectable 3,800 horsepower. Also, using GM's D87 traction motors the model could produce a continuous tractive effort rating of over 62,400 pounds continuous and 65,000 pounds starting.
However, what really set the EMD GP60 apart from earlier Geeps was its advanced on board computers and microprocessors which controlled everything from the engine's performance to braking applications. While these advanced computers required a more specialized mechanic to maintain they replaced numerous relays and wires. This sensitive equipment could be found to the rear of the cab interior behind the electrical cabinet doors. Interestingly, despite the very late date of the GP60s cataloging a cabless B version was also offered. Sales for this variant, however, was purchased only by the Santa Fe which picked up 23 examples numbered 325-347.
From a sales standpoint the EMD GP60 was somewhat successful. However,
only a few Class Is ultimately purchased the model including Norfolk
Southern, AT&SF (40, numbered 4000-4039), Southern Pacific/St.
Louis-Southwestern Railway (195, numbered 9600-9794), and the Rio Grande
(3, numbered 3154-3156). Additionally, the U.S. Department of Energy
purchased one and the Texas Mexican Railway picked up two (869-870).
It was the Santa Fe who appeared to like the EMD GP60 most, and liked to
employ the units in fast freight service along its Chicago-Los Angeles
main line. Even though the SP had the largest fleet the AT&SF owned
the most variants.

GP60M Production Roster
GP59 Production Roster
Along with purchasing B units it also picked up 63 examples (numbered 100-162) known as GP60Ms. The only difference in the GP60M was its wide, safety cab. No common in contemporary railroading the wide cab design was just catching on in the late 1980s. The AT&SF received its order of these locomotives between May and September, 1990. Despite only a few hundred being built most GP60s remain in use due to their relative young age and reliability (some, however, have been wrecked during that time and subsequently scrapped).
