Abstract: An equalized or compensated suspension system is reproduced in a model of a locomotive and comprises an arrangement of levers and/or dummy leaf springs which are interconnected by links so as to imitate the suspension system of the original locomotive. The model locomotive has a chassis and generally vertically reciprocable wheel axles mounted along the chassis. Springs are disposed in housings fixed to the model's chassis and are arranged to act at opposite ends on the wheel axles and associated levers or dummy leaf springs of the suspension system.

Abstract: In a model of a steam locomotive having two independent sets of driving wheels, the single electric motor for driving the model is coupled to the two sets of driving wheels via a differential gear. The latter allows the two sets of driving wheels to alter their angular positions relative to each other, owing to track irregularities and other causes, and thereby enables the model to operate more realistically.
