Abstract:
A track and linkage device for a locomotive designed to run on a track and powered by a turbofan engine comprises a track defining a channel having an open upper end and a plurality of ball bearings in the channel such that at least a portion of the ball bearings project through the open upper end of the channel. The ball bearings are at least partially coated with a material for reducing friction. A connector is associated with locomotive and has a slide surface thereon which slides on the ball bearings in the track. The slide surface includes a material on at least a portion of thereof for reducing friction when moving over the ball bearings.
