Prototype Overview:

From coach and freight yards to primary power for shortlines, the WalthersMainline SW7 is a perfect choice for your HO layout! Delivering 1200-horsepower from an updated 567A prime mover, the prototypes proved popular with both railroads and industrial lines, with nearly 500 produced in just two years. This model is based on Phase II production units constructed from 1950 to 1951 with several still in service.
