Abstract: A strong, lightweight monorail guideway assembly for carrying a monorail train vehicle in transport having selectively joined load-bearing rails which are structurally reinforceable on site in relation to support columns holding the track in suspension. Variations in stresses placed on the track are accommodated by the track structure while minimizing overall weight and material consumption. An easily accessible hollow interior provides protection and serviceability for electrical conduit placed therein. A conduit immediately adjacent the running surface may be selectively heated to inhibit icing.

Abstract: A monorail track switch and method is disclosed wherein the track switch senses the approach of a train and automatically aligns itself to accommodate passage of the train. Circuits are provided to selectively deenergize a movable track section when in nonaligned position and to re-energize the track section when properly aligned. Novel structure and method is also provided for lowering the movable track section onto rollers to facilitate movement and thereafter lifting the track section into horizontal alignment with the train path. Electronic lockout circuits prevent a train from overrunning the switch when the switch is in a nonaligned position.
