Train Tracking
The Visual Dispatcher uses the main block diagram to perform automatic train tracking.
Whenever a block is reported as occupied, because one of the indicators assigned to it is
turned on, then the Dispatcher checks, whether there is an appropriate train in an adjacent
block. An adjacent block is a block that is connected with the current block with a
link in the main block diagram.
If there is such train, then the train is moved to this block. This is done by automatic assignment
of the train to the new block and releasing of the previous block.
As a result of this movement the name and/or image of the engine or train appears in
the block symbol of the related block in the Visual Dispatcher. Additionally the train
disappears from the symbol of the previous block. If there are one or more optional
traffic boxes in a switchboard window associated with these blocks, then the train
movement will be visible in these boxes, too.
If there are more than one train located in adjacent blocks, than the Dispatcher tries to
determine the most probable candidate. For this calculation the speed of each train and
the direction of travel, if known, or the occupancy state of each adjacent block is taken
into account.
In order to achieve precise results it is important to assign the initial position and orientation
of each train correctly. Additionally you should always ensure that the software is
able to track the direction and speed of each train. The control of trains that you operate
with the throttle of your digital system should properly be assigned to the digital system
(see 3.11, “Passing control between Computer and Digital System”).
Train tracking can also be disabled for certain blocks or temporarily for the complete
layout. This is useful for areas or in situations, when you put new engines or trains
manually on the physical track and you want to avoid unintentional train tracking
caused by the resulting occupancy messages.
Attention: train tracking is turned on by default. Unintended triggering of indicators,
that are assigned to blocks, might cause train assignments to be moved in the
block diagram. If this is not desired in certain situations then train tracking can be
(temporarily) disabled for the complete layout.
• Under the conditions listed below train tracking works for each engine or train on
the layout, which has been previously assigned to a block.
