Abstract
A double turnout rotary guideway switch is provided with an elongated structural frame member having guidebeam, electric rail and tire path structure on each of two sides of the switch compatible with the guidebeam, electric rail and tire path structure of the guideway. Two elongated beams form the sides of the frame and, with cross connected end beams, operating as the principal structural members for the frame. A curved beam extends from one of the elongated side beams inwardly and to one of the end beams. Opposite sides of the curved beam provide respective surfaces for a left turnout tire path on one of the two sides of the switch and a right turnout tire path the other side of the switch.
