Claim 1
Independent Claim
196 words
In a transportation system characterized by a track system and trains composed of individual vehicles moving along a main track said system including a secondary track having a separate steering rail by which vehiCles may be diverted at a left or right hand turn-out from the main track to the secondary track to stop at a station, said secondary track later joining the main track so that diverted vehicles may be re-directed to re-enter the main track to join another train, a slide on the vehicle fitted at opposite ends with opposed coupling rollers respectively engageable with a steering rail accordingly to steer the vehicle at and through a turn-out, each vehicle including selectively operable electric motor means carried thereby to operate the slide and thereby select a steering rail whereby the vehicle may be so diverted through a left or right hand turn-out to follow the selected steering rail to the secondary track, each vehicle having its own propulsion system whereby it may move along the secondary track to the station and after a station stop may be propelled out of the station along the secondary track to join a train on the main track.
