Facing stiff competition from General Electric and EMD, Alco sold only 27 of the RS-27 model. Over half, 15, went to the Pennsylvania. Historically, the locomotive might be completely forgettable were it not for the fact that it previewed many of what would become the new standard features of Alco's Century series. With its unique look and distinctive Alco sound (and smoke), the RS-27 will make a novel addition to your layout. Whether it's hauling a fast mainline freight or working on a small branch or shortline, these colorful diesels will be a delight for Alco-haulics everywhere.
