A route relation states the conditions that must be fulfilled for a given signal to be open. <br /></p><p>The signalling engineer can impose relations such as simple flank protection or more complex route relations. <br /></p><p>In terms of usage in interlocking operation, this means an observer pattern: a change of state of a given set of track assets produces a change of the signal state. In other words, the signal observes elements. A new state produces an update in the signal state.<br /></p>
