1. An apparatus for detecting the information about a guideway-guided vehicle having a masking component, the guideway-guided vehicle configured to follow a path of a guideway, comprising a radio frequency identification (RFID) system comprising:

  • a first RFID transponder for transmitting, across the path, first RFID transponder specific information;

    an RFID reader having a first antenna for receiving the first RFID transponder specific information; and

    wherein the first RFID transponder and the first antenna are fixed relative to the path and on opposite sides of the path;

    wherein the RFID reader is configured to substantially continuously monitor the first transponder specific information; and

    wherein the presence of the masking component of the guideway-guided vehicle between the first RFID transponder and the first antenna masks the substantially continuous monitoring of the first RFID transponder specific information.
