TrainController Gold and Silver - Freiwald Software

Diagram 109 has been derived from Diagram 105 by eliminating sensor A. It is assumed
that the block is only passed from the left to the right. B acts as brake marker
and C as stop marker for trains running to the right.
The different configurations discussed in this section are only examples. Configurations
similar to Diagram 109 can also be made with momentary contacts instead of occupancy
sensors or with a mixture of both types similar to Diagram 106. One can think also
of other configurations. There is no best way to setup a block. The optimal solution
does not only depend on technical requirements but also which equipment you already
have and how much money you want to spend on new equipment.

One Sensor per Block: Shifted Brake or Stop Markers
In the examples discussed so far, all locations, where trains stop or begin to brake are
identical to the entry of an occupancy section or to the point, where a momentary track
contact is triggered. In Diagram 108 we even installed an extra sensor to isolate the location,
where the entrance into the block is reported, from the location, where the train
begins to brake to gain time for activation of subsequent routes.
But it is not essential to install extra sensors for this purpose. It is also very easy to specify,
that a stop marker is located in a certain distance from the point, where the associated
sensor is turned on. This is done by specifying a distance for such marker. This
creates a shifted stop marker.
Diagram 110: Shifted Stop Marker
If your trains run very precisely and have been profiled accordingly
, then it is not necessary
to install a separate sensor to mark the stop point C. Instead it is possible to
mark the occupancy sensor B with a brake marker and a shifted stop marker for stop
point C.
