To an Alcophile, there's nothing sweeter than the wheezing, barking sounds produced by a smoke-belching Alco diesel. In this three-volume series, Pentrex sets out to document an example of every Alco model remaining in operation, exploring the qualities that make these remarkable locomotives so attractive to their fans.

Volume 2 covers the early 251-powered Alcos. Searching North America for surviving examples of models introduced between 1955 and 1962, these "notch-nosed wonders" are chronicled from their beginnings to the introduction of the Century line. Alco models S-6, RS-11, RSD-12, RSD-15, T-6, RS-27, RS-32, and RS-36 diesels are viewed in operation, as well as Montreal Locomotive Works RS-18, RSC-14, FPA-4, S-13, and RS-23 units.

Join us for thrilling action as burbling diesels spew clouds of black smoke and produce that tantalizing Alco sound. You'll ride in four different locomotive cabs including our favorite, the rare RS-27. Informative production statistics and spotting features are shown for each model. "Mr. Alco" George Hockaday shares his experience and clears up some often misunderstood facts about Alco and its diesels. Those Incredible Alcos put on an amazing show!
