PROTOTYPE SPECIFIC INFORMATION
The EMD GP50 is a 4-axle diesel road switcher locomotive built by General
Motors Electro-Motive Division between 1980 and 1985. It is powered by a
16-cylinder EMD 645F3B diesel engine, which can produce between 3,500
and 3,600 hp.
A total of 278 examples of this locomotive were built. The GP50 retains
the same overall length of 59 feet 2 inches as the other GP dash-2 series
locomotives built in the same era. It utilized GM’s D87 traction motor enabling
it to produce a starting tractive effort of 65,000 pounds, with a continuous
rating of 62,400 pounds.
The most significant difference in the GP50 from earlier designs like the GP40
was upgraded components (like a turbocharger silencer and new type of
blower housing) and increased horsepower. The locomotive also introduced
a new “anti-wheel-slip” technology where the locomotive horsepower output
was reduced if a wheel slip condition was introduced. It also included features
already common on earlier models such as dynamic braking (a system for
temporarily employing traction motors as generators and using the resulting
electromotive force to slow the train), and an airtight hood that kept out dust,
dirt and other particles from reaching internal components.
All the companies that purchased the GP50 have now been absorbed into
other systems. However, a few of their successors continue to operate the
units. A number GP50s have rebuilt for better fuel economy and continue in
service today.
