Railroad Short Name: UP
Prototype Specific Information
In the decade between 1974 and 1984, EMD produced the
GP39-2 for seven North American railroads. The basic design followed most four axle road diesel switchers for the time. Borrowing improvements from the GP38-2 and GP40-2 designs, this mid-horsepower road switcher utilized a turbocharged 12-cylinder EMD 645E3 diesel engine for it’s prime mover. With 4 fewer cylinders, the smaller engine provided a distinctive long hood on the phase II and phase III bodies, where the clean room/engine compartment doors were set back from the cab further than predecessor locomotives.
Sensitivity to fuel economy in the 1970s justified the GP39-2 in the locomotive market. It also laid the ground work for EMD to start exploring locomotive designs that utilize engines with larger piston displacement yet posses fewer cylinders. This approach has become the foundation to modern locomotive technology.
UP Features:
- Former MKT units
- Correct GP49-style carbody details
- Details to match recent in-service photos
- Front and rear operating ditch lights
With the 1988 acquisition of the Missouri-Kansas-Texas Railroad by Union Pacific, all of the former road’s motive power began to be assimilated. Some of the newest units on the roster were a group of 20 GP39-2s that had been built in 1984. They survived to serve UP for many years and wear a variety of paint scheme variations.
