HO PA-1 + PB-1 Locomotive Set with DCC & Sound, ATSF #51A, 51C (RPI23546)

HO-scale Santa Fe ALCO PA-1 and PB-1 Locomotive Set with DCC & Sound brings to life the famous repowered PA/PB pair used by the Santa Fe in the mid-1950s. This two-unit set, numbered 51A and 51C, reproduces the 1954 upgrade to EMD 567C power for about 1,750 horsepower and features the distinctive raised mid-body, roof blister, and four button-top EMD-style fans that gave these locomotives their unmistakable silhouette. Accurate nose and roof profiles plus road-name detailing provide an authentic Santa Fe look on HO layouts.

The set offers modern operation with DCC and sound options, including a LokSound V5 decoder for realistic engine sounds and responsive control. It includes a wealth of detail—separate factory-installed grab irons and handrails, etched grilles, lit number boards, a full cab interior and full underbody piping and conduit—and supports dynamic or non-dynamic braking where appropriate. Optional A-unit and A-B configurations help build longer consists, while features such as operating Gyralite or a red Mars light add extra realism for a convincing Santa Fe roster.
