Rapido HO Scale Alco PA/PB Denver and Rio Grande Western RR review

The ALCO PA was a family of A1A-A1A diesel locomotives built to haul passenger trains. The locomotives were built in Schenectady, New York, in the United States by a partnership of the American Locomotive Company (ALCO) and General Electric (GE) between June, 1946 and December, 1953. Designed by General Electric's Ray Patten (along with their ALCO FA cousins), they were of a cab unit design; both cab-equipped lead A unit PA and cabless booster B unit PB models were built. While externally the PB models were slightly shorter than the PA model,[1] they shared many of the same characteristics, both aesthetically and mechanically. However, they were not as reliable as EMD E-units.[2] ALCO's designation of P indicates that they were geared for higher speeds and passenger use, whereas the F designation marks these locomotives as being geared primarily for freight use. However, beyond this, their design was largely similar - aside from the PA/PB's both being larger A1A-A1A types with an even more striking nose - and many railroads used PA and FA locomotives for both freight and passenger service. Although the majority of the PAs and PBs have been scrapped, six examples have survived. Five PAs are now preserved in railroad museums, while a converted PB still remains in service as a power car.
