In switching apparatus for a mass transit vehicle having support wheels and controllable to pass from a first roadway onto a selected one of a second roadway and a third roadway, with said apparatus including a pair of tracks for said support wheels, the combination of
- two guide members positioned between said tracks and with each of said guide members having a top flange,
- first guidance means connected to said vehicle and in substantially fixed position relative to said vehicle to pass between and cooperate with said two guide members,
- second guidance means connected to said vehicle and movable in position relative to said vehicle to be cooperative with one of said two guide members for controlling the vehicle to pass onto the second roadway, and
- third guidance means connected to said vehicle and movable in position relative to said vehicle to be cooperative with the other of said two guide members for controlling the vehicle to pass onto the third roadway.
In apparatus for controlling a mass transit vehicle having support wheels to switch from a first roadway onto a second roadway, with said apparatus including a pair of tracks for said support wheels, the combination of
- two guide members positioned between said tracks and with each said guide member having a top flange,
- a first guide wheel connected to said vehicle in substantially fixed vertical position for operation relative to and between said two guide members,
- a second guide wheel connected to said vehicle and movable in vertical position relative to said two guide members and selectively operative with one of the latter guide members to provide a first predetermined operation of the vehicle in relation to the second roadway, and
- a third guide wheel connected to said vehicle and movable in vertical position relative to said two guide members and selectively operative with the other of the latter guide members to provide a second predetermined operation of the vehicle in relation to the second roadway.
In apparatus for controlling a mass transit vehicle to pass from a first roadway onto a selected one of a second roadway and a third roadway, with said apparatus including a pair of tracks and a first elongated guide member and a second elongated guide member, with each said guide member being positioned between the roadway tracks and including a top flange, the combination of
- first guidance means connected to said vehicle in substantially fixed vertical position relative to each of the first and second guide members when the vehicle is passing through said apparatus such that the first guidance means passes between and along the length of the first and second guide members,
- second guidance means connected to said vehicle and movable in vertical position relative to the top flange of the first guide member for controlling the vehicle to pass onto the second roadway, and
- third guidance means connected to said vehicle and movable in vertical position relative to the top flange of the second guide member for controlling the vehicle to pass onto the third roadway.
