摘要： A switching arrangement for an elevated track having upper and lower rails includes a pair of first upper and lower switch beams at a switching interruption along the track, the beams being movable from a position of rail alignment with the upper and lower rails to a position shifted toward on another. For switching a rail vehicle to a secondary track, a pair of second upper and lower switch beams are provided at the switching interruption for movement toward and away from one another between a position out of rail alignment with the upper and lower rails to a position into alignment therewith when the first beams are shifted toward one another.
