How does a railway token work?

Upon successful detection of the token, the driver's cab display instantaneously reflects the commencement and termination points of the authorized track segment. This visual confirmation ensures that the train operates within the designated limits, enhancing safety and efficiency.

The "token" serves as a pivotal digital sequence transmitted wirelessly, enabling the seamless communication between the train and its operating system. Its primary function is to authorize the train's movement within a specified section of the track.

The token system operates on a dynamic principle, adapting to the train's movement. Once the train has traversed the authorized section, the driver initiates a reversal process, effectively "handing back" the token via the same radio LINK mechanism.

This return process signifies the completion of the train's journey within the allocated section and prepares the token for reuse by another train or for the same train's subsequent journey. It ensures that the token remains a scarce and valuable resource, preventing unauthorized or simultaneous access to the same track segment.
