System and method for controlling a train travelling along a railway line

A system for controlling a train travelling along a plurality of track blocks of a railway line, the system comprising at least:

• at least one first signal transmitter which is installed at a first track block of the plurality of track blocks, the at least one first signal transmitter being configured to transmit, using a predefined range of transmission frequencies, first signals suitable to allow detecting when the train enters into the first track block;
• at least one second signal transmitter which is installed at a second track block of the plurality of track blocks adjacent to the first track block, the at least one second signal transmitter being configured to transmit, using a predefined range of transmission frequencies different from the predefined range of transmission frequencies used by the at least one first signal transmitter, second signals suitable to allow detecting when the train enters into the second track block;
• one or more signal receivers which are installed on board of the train and are configured to receive the transmitted first and second signals;
• and
• a controller which is installed onboard of the train and is configured, based on signals supplied by said one or more receivers indicative of the first and second signals received, to identify when the train enters the first track block or the second track block.
