A toy cog wheel railway is provided having a track with smooth driving faces and a center cogging member with two opposed vertically extending racks thereon. The associated train has an engine with a driven chassis and further cars with undriven running chassis. The chassis contain wheels with smooth faces to run on the driving faces of the track. The undersides of the chassis are provided with opposed guide members that contact the opposed sides of the cogging member. The driven chassis is provided with a motor whose drive axis is vertical with respect to the driving faces of the track and is offset with respect to the center line between the guide members so that a cogwheel attached to the drive axle engages only one of the racks. The chassis are further provided with coupling arm including a yoke having two deflected arms which are pivotally mounted to the chassis at a height approximate that of the drive motor cogwheel and the guide members, respectively, and in the longitudinal direction approximate that of a vertical plane containing the center of gravity of the respective chassis.
A toy cog railway system having a train and an associated track, said track including at least one smooth driving face and a cogging member mounted along said driving face and extending perpendicularly to said driving face, said cogging member being provided with two teeth-bearing racks transversely spaced apart from each other, said racks being disposed symmetrically with respect to said driving face, the longitudinal direction of the teeth of said rack extending perpendicularly to said driving face, said at least one smooth driving face having the form of a flat strip;
A track for a toy cog wheel railway, said track including at least one smooth driving face and a cogging member mounted along said driving face and extending perpendicularly to said driving face, said cogging member being provided with two racks transversely spaced apart from each other, said racks being disposed symmetrically with respect to said driving face, the longitudinal direction of the teeth of said racks extending perpendicularly to said driving face, and said at least one smooth driving face having the form of a flat strip.
An engine for a toy cog wheel railway, said engine including at least two axles each having rimless wheels, a drive motor in engagement with a cogwheel for engaging a track cogging member having a pair of racks on opposite sides thereof, the rotating axis of said cogwheel extending perpendicularly to said axles, and means for guiding said engine along a driving face of said track including at least one pair of opposed guide means formed to contact sides of said cogging member, said cogwheel being laterally displaced with respect to the center line between said guide means so as to engage a single one of said racks.
