15.2 Virtual Contacts and
Virtual Occupancy Indication
General
Virtual Contacts are similar to normal contact indicators (see section 4, “Contact Indicators”).
But unlike contact indicators there is no related track contact or real sensor on
the model railroad. Instead virtual contacts are assumed to be located at a specific distance
from another indicator, which is called the reference indicator.
Virtual contacts can be used to reduce the number of necessary track sensors on your
model railroad. Typical applications are triggering of operations by passing trains a certain
distance from an existing sensor (see also section 14.4, “Operations”).
After creation of a virtual contact the following properties are specified:
• a maximum of two reference indicators, one for each direction of travel (see section
5.3, “Direction of Travel vs. Engine Orientation”). These indicators must already
be assigned to a block.
• the distance from the specified reference indicator
• whether the virtual contact will be turned on, when the head, the middle or the tail
of a train passes the point, where the virtual contact is assumed to be located
