RailKing One-Gauge equipment offers long-lasting, impact-resistant polycarbonate bodies, powerful flywheel-equipped DC can motors, and precise 1:32 scale proportions and detail. Features include metal handrails, spinning fans, constant voltage lighting, puffing smoke timed to the engine's chuffing, firebox glow, cab figures, sliding cab windows, and much, much more. In addition to the eye-popping detail, the line is built tough for years of outdoor operation.

RailKing One-Gauge's 1:32 scale models are designed to work with existing equipment. The engines and cars run on existing standard 2-rail 45mm DC-powered track systems, including the Code 215 rails used by fine scale railroaders and LGB's 332 track. Each locomotive includes two sets of couplers, a knuckle coupler and a hook & loop coupler, so they can easily be adapted to mate with other garden-sized train systems.
