The Walthers Mainline 910-20724 models an Alco RSC-2 decorated for Union Pacific as road number 1284. A six-axle version of the four-axle Alco RS2, the RSC-2 spread its weight across the lighter rail of branch and secondary lines. First built in 1946, the 1,500 hp RSC-2 handled freight and passenger service as well as yard switching from the 1950s into the 1970s. Accurately sized, this HO scale model captures the prototype's character, including its distinctive long trucks.

Item 910-20724 is equipped with ESU Sound and DCC for DCC or DC layouts, offering 4, 28, or 128 speed steps, dual-mode DC and DCC operation, four air horns and two bells changeable by CVs, and a 21-pin DCC plug. Its drive matches that of Walthers Proto locomotives, with a five-pole skew-wound motor, 14 to 1 gear ratio, helical-cut gears, all-wheel drive and electrical pickup, a machined brass flywheel, and a heavy die-cast metal chassis. An air- or water-cooled exhaust stack is applied as appropriate, and molded drill starter points let you add curved Alco grab irons with the Walthers Mainline RS2 Diesel Detail Kit (910-260, sold separately).
