Virtual Occupancy Indication
If an indicator is associated with a momentary contact then this contact can be upgraded
with the memory of the indicator to a virtual occupancy sensor (see section 14.2, “The
Memory of Indicators”). If this is done the indicator stays on after activation of the contact
until the complete train has passed the point where the contact is located. It is possible
to take into account the point where the contact is activated or the point where the
contact is deactivated. In this way it is for example possible to avoid premature release
of routes in cases when long trains pass a route and only momentary contacts are used.
This option works only for trains under control of the Dispatcher and it relies on correct
specification of the length of each train.
Virtual Contacts can be combined with Virtual Occupancy Indication, too. The Memory
is namely also available for Virtual Contacts. In this way a Virtual Contact will be
turned on when a train reaches a certain point on the layout. And the Virtual Contact
will stay turned on, until the last car of the train has passed this point.
Please note the difference between Virtual Contacts and Virtual Occupancy Indication.
A Virtual Contact marks a certain point on your model railroad, i.e. a Virtual
Contact is turned on, when a train is assumed to arrive at a certain point. Virtual
Occupancy Indication is used to turn a certain real or Virtual Contact off
when a train has passed a certain point completely.
15.3 Controlling the traffic flow in Schedules
Limiting the Reservation of Blocks and Routes in certain Schedules
For each block and each route in a schedule it is possible to specify a condition. This is
a condition, which must be valid when a block or route is about to be reserved during a
running schedule. As long as the condition does not apply it is not possible to reserve
the block or route. How conditions work is outlined in section 14.3, “Protection and
Locking with Conditions”.
This feature provides additional control. It is for example possible to specify, that a certain
block may only be reserved, if a certain on/off switch is toggled off. Turning off or
on this switch you can intervene into the traffic flow at any time and lock or release the
affected block.
Such conditions can be specified on a global or a per-schedule base. Global conditions
are specified as part of the properties of blocks or routes as outlined in section 14.3,
