Big or small, your railroad needs the power of WalthersMainline SW1 diesels! These HO workhorses can tackle any switching assignment, and are a favorite with heavy industries too. The detailed body is complete with bell, exhaust stack, as-built headlight, air horn and applied wire handrails, while molded starter points make it easy to add grab irons (sold separately). Under the hood, a powerful five-pole motor with dual flywheels and 14:1 helical gears lets them creep quietly through yards and sidings, while the heavy die-cast metal frame gives the extra weight needed for solid pulling performance. For a limited time you can get a pair of locos in your favorite roads, each with different unit numbers, and enjoy geat savings while supplies last!
