PROTO 2000 Alco RS-27s Bring a Distinctive Prototype to HO Scale As the horsepower race between major locomotive builders began heating up, ALCO rolled out its new RS-27 in late 1959. While the design used the running gear of the RS-11, the new model was powered by a larger 16-cylinder prime mover that generated 2400 horsepower. To accommodate its extra length, the cab was moved forward, and the front hood shortened, giving the RS-27s a very distinctive appearance. Under relentless pressure from GE and EMD, ALCO was able to sell just 35 RS-27s before production ended in 1962. ALCO's last road switchers have long been a favorite with modelers. The PROTO 2000 models mark the first time these distinctive diesels have been offered in plastic.
