ABSTRACT:
Stopping zones in a linear motor in-track transit system are provided. The transit system includes a guideway and at least one vehicle moveable along the guideway between freight loading and unloading stations. Stopping zones are designated at certain segments of the guideway where it is necessary to stop a vehicle. The stopping zones include a primary brake in the form of a linear motor primary which is operable under normal conditions to stop the vehicle in the stopping zone at a designated stopping point when the vehicle enters the stopping zone. The linear motor primary is also operable to restart a vehicle it has stopped. A secondary brake is also provided along the guideway within the stopping zone and is spaced from the primary brake. The secondary brake typically remains inoperative but is also capable of stopping a vehicle within the stopping zone when the vehicle travels beyond the designated stopping point due to failure or malfunction of the primary brake. Preferably, a restart device in the form of a second linear motor primary is also provided adjacent the secondary brake to restart a vehicle stopped by the secondary brake.
