Tract beam

A beam for a railway track guided vehicle system configured to be supported at spatial intervals on piers includes an upper flange disposed along a longitudinal length of the beam. The upper flange has opposite laterally outward portions configured for receipt of functional elements for guidance of a track vehicle. Opposite side webs extend downwardly from the upper flange along the longitudinal length of the support. A lower flange is disposed at ends of the webs opposite from the upper flange and is disposed longitudinally along the length of the support. The beam includes a uniform cross-sectional shape along a longitudinal length thereof so as to generate favorable air flow conditions for the track guided vehicle. The lower flange has a lateral dimension so as to essentially cover an underlying pier. In this way, the pier does not cause air flow disturbances to the track guided vehicle.
