RoadRunner PLUS


    The RoadRunner+ fits a wide variety of locomotives and is our most popular box. The articulated, shape-shifting design enables you to configure it to suit a huge range of applications without either the motor or the gearbox being visible.


    Choose any of three gear ratios to further enhance the versatility of the design – sitting in the firebox of an express engine, squeezing maximum power and performance from a big, mixed-traffic tank, or making best use of limited space in a small shunter.
