Trackside key token machines use trapped key technology to control the issue of physical key tokens and to signal and control trains through individual railway track sections. Data (e.g. headcount and roll-call data) is communicated between the token machines and a remote central control unit, e.g. by wireless transmission of messages encrypted using TERN technique. The central control unit analyses the data to count and account for key tokens and controls the issue of tokens by the token machines. Drivers may be identified by RFID during token transactions and trains may carry GPS. The central control unit may include a user interface to inform a controller of the status of tokens, track sections and trains. The system requires no fixed infrastructure (e.g. token machines may be portable and need no cables between them); nor does it require trains to carry electronic devices.
