Abstract
The present invention provides a drive assembly for a model toy train which connects a single drive shaft from an electric motor to a pair of discrete truck assemblies. The drive shaft drives a plurality of pinions which in turn drive a pair of worm shafts which extend toward the truck assemblies. A pair of worm wheel shafts are driven by the worm shafts to drive the wheels on the truck assemblies. A saddle and bearing combination rotationally connects the model toy train to the truck assemblies allowing the truck assemblies to freely rotate.
