TrainController Gold and Silver - Freiwald Software

ture of many layouts is much more complicated. It can contain reversing loops or several
levels, it can be based on a modular structure, etc.
For this reason TrainController uses the logical polarity scheme described above. If
the layout displayed above is wired in a way that the track power will not change its polarity
when a train cycles around the loop, then the train will pass “Hidden Yard 1” and
“Southtown” to different logical directions (left or right), even though the physical polarity
of the track power remains unchanged. A train that passes “Hidden Yard” to the
right at positive track polarity will pass “Southtown 2” to the left at the same track polarity.
As a consequence “Hidden Yard 1” and “Southtown 2” have different logical polarity
from the point of view of the software. The differences with regard to the logical
polarity of the particular blocks are marked with a yellow or blue arrow in the diagram
displayed above.
Running conventional and digital Engines on the same Track
This is supported with an additional option. Each block, on which conventional engines
as well as digital engines will be able to run, must be arranged for dynamic decoder assignment
(Computer Cab Control, unless the RCI system is used - see below). Additionally
it is possible, to assign one extra on-off switch to each affected block (see Diagram
186). This additional on-off switch is used to turn on and off the “digital power”
for this block. Whenever the block is reserved for a conventional engine, then the block
is automatically connected to an appropriate stationary block decoder as outlined in the
section before. When the block is reserved for a digital engine, then the extra on-off
switch is used to turn on the “digital power” for this block.
In this way it is even possible to run conventional and digital engines in different blocks
of the same track at the same time.
The Track Driver Cards of the RCI system provide a built-in feature to route DCC
power directly to the output points. This feature is used, when a block is statically assigned
to a stationary block decoder on a Track Driver Card (Computer Section Control).
Whenever a block is reserved for an engine with an own DCC decoder, then the
DCC mode is automatically turned on for the Track Driver point connected to this
block. When the block is released, then the DCC mode is turned off.
Notes
You can use regular engine decoders of any digital system as stationary block decoders.
To use an engine decoder as stationary decoder, mount it at a fixed position of your
model railroad and connect the wires, which are normally connected to the motor, to the
