摘要： Trackway guided vehicles are constrained to travel in a selected branch of a trackway switch by electromagnetic attraction with the electromagnets also serving as elements of a linear electric motor. Magnetic field strength sensing means detects the presence or absence of the electromagnetic field on a diverging switchway and controls actuation of guideway interlocks to restrict vehicle travel selectively in the left or right exit branch of the switch in the event of power failure to the electromagnets.
