The at least one magnet is responsive to the at least one linear motor. A linear motor controller 70 is operatively connected to the at least one linear motor, and a lane controller 80 is operatively connected to the linear motor controller. A back electro-motive force (EMF) module 84 is operatively connected to at least one of the linear motor controller and the lane controller. The lane controller being configured and disposed to control stopping one of the one or more cars based on a back EMF signal from the at least one linear motor determined by the EMF module. |
