ABSTRACT:
Improvements are provided in a rapid transit system which employs a guide line network including a main line and an interconnected side line, a car moveable throughout the network and interconnected thereto by an overhead tow bar, car drive means, and switch means for diverting the car to and from the main line and side line. The improvements include an overhead main line guide bar at and around intersections of the main and side lines, a main line guide finger vertically moveable from within the car into and out of sliding engagement with the main line guide bar, an overhead side line guide bar at and around said intersection, and a pair of turn-off guide fingers vertically moveable as a unit from within the car for sliding engagement with the side line guide bar to divert the car to the side line. These fingers are spaced lateral of both sides of the main line guide finger. Lever means in the car alternately raise and lower the turn off guide fingers and main line guide finger. The leading ends of the guide bars can be rotated or otherwise moved by remote means to control the direction of the car in an emergency. A platform with guide openings under the car at the intersection cooperates with wedge shaped guides on the car bottom to aid the car in turning into the side line. Slides on the platform aid the car bottom to slide on banded portions during turns.
