Abstract
A system and method are for controlling a train traveling along track blocks. A first signal transmitter is installed at a first track block and transmits, using a predefined range of transmission frequencies, first signals for detecting when the train enters the first track block. A second signal transmitter is installed at an adjacent second track block and transmits, using a predefined range of transmission frequencies different from the predefined range of transmission frequencies used by the first signal transmitter, second signals for detecting when the train enters the second track block. One or more signal receivers on board of the train are configured to receive the transmitted first and second signals, and an onboard controller is configured, based on signals supplied by the one or more receivers indicative of the first and second signals received, to identify when the train enters the first or second track blocks.
