Changes

Where intermediate an siding exists where a train may be locked in, it is possible to provide an intermediate instrument in into which the token may be placed once the train is clear of the running line and the points are set appropriately.<br>When the token has been placed into the intermediate instrument signalmen at either end may withdraw a token from their local instrument to allow another train to run between the two signal boxes in the manner described previously.<br>This method of working is available for use when [[Arley]] is switched out. The long ([[Bewdley]] to [[Highley]]) section token may be used in an intermediate instrument using the signal-box as a ground frame.
