The rule to release preceding blocks and routes of a certain schedule at the stop indicator
of subsequent blocks should be turned off only, if the routes contained in this schedule
are equipped with an own occupancy indication. Furthermore the tail of each train
should be able to trigger the sensors used for occupancy indication of the routes. Usually
this requires, that the trailing cars of affected trains are lighted or the wheel sets of
these cars are conductive.
Occupancy indication of routes can also be used to detect cars lost in a turnout area or
to prevent routes from being prematurely released, when a long train is completely filling
the subsequent block, but the tail of the train is still located on the route. In this case
the route is not released, even if this long train has reached the stop indicator of this
block (exception: the block is the destination block of a schedule, in which case all
routes contained in this schedule may be released).
Schedule Watchdog and Limited Aberration Protection
With a specific schedule rule it is possible to specify a schedule watchdog. This is the
maximum time period between activation of two indicators. If no indicator is triggered
within the specified period of time and the train is set to run at non zero speed, then it is
assumed, that the train got stuck. In such cases a warning is displayed in the message
window and an error indication is raised in the train list.
It is furthermore possible to activate a limited aberration protection for each schedule. If
the train under control of this schedule is detected by train tracking in block, which
does not belong to the schedule, then the train is stopped immediately, a warning is displayed
in the message window and an error indication is raised in the train list. Such
condition can occur, for example, if a turnout contained in the schedule does not work
correctly and the train is directed to a wrong block.
The limited aberration protection can detect certain, but not all possible conditions,
where trains run into wrong blocks. In particular it usually cannot protect
the train against collision, if the wrong block is already reserved by another train.
Aberration protection should not be misunderstood as collision protection and it
does not rid you from arranging for reliably working hardware.
Track Cleaning Trains
With a specific schedule rule it is possible to specify, that always that path is selected,
that contains routes or blocks, which have been visited by the train under control of this
schedule the longest time ago (“oldest” block or routes).
