- EMD BL20-2
The EMD BL20-2 is a
diesel-electric locomotivethat was introduced in order for EMD to gain entry to the rebuild market for the second time.
All three BL20-2 demonstrators, road numbers 120-122, were built on the 56 foot, 2 inch frames of ex-
Burlington NorthernGP9s of Chicago, Burlington & Quincy, Northern Pacificand Spokane, Portland & Seattleheritage. All three demonstrators were outshopped from La Grange in mid- 1992. They bore no resemblance to the pre-GP series EMD BL1and BL2 models of the late 1940s. Neither did they resemble GP9s, at least not from the frame up. On the inside, the unit married the technology of two generations, with a rebuilt 16-567 engine (turbocharged to boost the output from 1750 to 2000 horsepower) mated to an AR10 alternator and Dash 2electrical system. Although the GP9 frame, trucks, traction motors, fans, and prime mover were rebuilt and reused, the locomotive received an all-new cab and carbody, basically that of a standard second-generation GP. Still, the unit had an unmistakable appearance, due to the absence of inertial air intakes behind the engineer's side of the cab, and the use of a squared-off dynamic brakeassembly similar to that of a GP60.
Competing in one of the toughest fields in the locomotive business, the three BL20-2s demonstrated for two years, but won no orders. They were redeployed to EMD's lease fleet in
1994, and have worked for several shortlinerailroads since then.
