ABSTRACT:
Improved stopping accuracy of track-bound vehicles at railway stations is obtained by spacing the phase reversal points of the track conductors at shorter intervals in the station area than on the line and, during a vehicle's approach to a stop, transmitting the exact location of the stopping point between any two phase reversal points to the vehicle, and activating the vehicle's own phase reversal detection logic for the duration of its stay in the station area.
