==Method of operation==
The signalman sending a train will alert the receiving signalman with the "Call Attention" [[Bell signals|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, and will reverse the Acceptance Lever. An indication is given in the other signalbox to indicate that this has been done.
Reversing the Acceptance Lever at the receiving end will unlock the signal which allows trains to enter the section of line between the two signalboxes at the sending end. The signalman will clear this signal, which is the only permission that trains need to enter the section. As the train departs, the sending signalman will check it is showing the correct tail lamp at the end of the train, and send the "Train Entering Section" bell signal to the other signalman. During the time that the train is in the section, the signalmen at either end are reminded of its presence by track circuit indications in each signal box, and by either the reversed Acceptance Lever in the receiving signal box or by the associated indication in the sending signal box.
