When a token has been removed from an instrument, it is usually placed in a 'token carrier', a metal holder which is about the same size and shape as an unstrung tennis racket. This enables the tokens to be passed to and from moving trains.
== Operation ==
The signalman sending a train will alert the receiving signalman with the 'Call Attention' bell signal, and when he or she responds will, by bell signal, ask "Is the line clear for [this kind of train]", there being different signals for different train types. If the receiving signalman accepts the train, he or she will repeat the signal back, keeping the bell plunger held down on the final beat of the signal. Holding down the plunger releases the mechanism of the sending signalman's token instrument, so he or she can remove a token.
Removing the token will unlock the signal which allows trains to enter the section of line between the two signalboxes. The signalman will clear this signal, put the token into a token carrier, and give it to the footpath crew.
