These mid-range gearboxes are designed to suit a huge variety of prototypes, from mixed-traffic 4-6-0s to tiny branch-line engines. Two-stage gearing gives enhanced mechanical efficiency at prototypical speeds.

Available in 3 configurations, all with a choice of 30,40 or 54:1 ratio, the RoadRunners give you more variety in less space than you'd have dreamed possible. With a good can motor, you'll be able to achieve smooth, slow running and a top speed in the region of 50-60mph ­ the speeds at which most steam-era trains actually ran.
