- The final part of [b]Route[/b] data is used to determine if a train is approaching. These conditions should evaluate to true in order to release the route immediately, if the route is manually cancelled. Generally speaking, if a train is within sighting distance of a signal that would change aspect because of a route being manually cancelled, then the route should become [b]approach locked[/b] (or "run time" in North American parlance) which returns the signal to danger but keeps the route locked for a time period in case an approaching train is unable to stop. Once the time period has expired, the route can then release. The time is anything from 30 seconds for a low speed shunting signal to several minutes for a higher speed main line signal. No Train Approaching data is not required for routes without approach locking (those which always time out, regardless of approaching trains), nor is it required for automatic routes.
