A look inside the token hut on platform 3 at Liskeard station. The red box is the token machine. The token hanging down from the centre slot is about to be taken by the train driver as permission to occupy the track between here and Coombe Junction. A second token is in the third cassette. Only one token can be removed from any of the token machines in the circuit but when the first token is locked into the Coombe Junction machine another driver could take the second token from this machine and so follow the first train without that train having to return its token to Liskeard.
