Diagram 144: Manual Control of Station Entry
This situation can be controlled with one single schedule, that is displayed in Diagram
144, too. The start and destination blocks of this schedule are located in block “South
1” and “South 2”. Since each schedule can be started in two directions, this schedule is
able to control trains that travel clockwise, as well as trains that travel counterclockwise.
When the schedule is being started in either direction, then we take care, that the entry
to both, “South 1” and “South 2” is locked. The started train will proceed to “East” or
“West”, respectively, and stop, if the lock has not been released until then.
By activating a route you can pre-select a path to “South 1” or “South 2”, respectively.
This route can be associated with a pair of start and destination keys. If additionally the
release of both blocks in “South” is performed as operation by each route, too, you are
not only able to pre-select a path with the start and destination key, but also to release
the lock which causes the train to continue its journey.
There are several possible variants. Instead of locking the entries to “South 1” and
“South 2” you can also lock the bottom exits of “East” and “West”, respectively. You
can also terminate the schedule in “East” or “West” and start another schedule with start
and destination key, that directs the train from “East“/“West” to “South 1” or “South 2”.
