2.6 Station groups
As described in the previous sections, Weasel
®
Lite systems always have a main loop with a variety of
stations (typically bays) branching off to the left or right. In some cases, there may also be secondary
loops within the main loop each of which may have various stations. Note that stations in secondary
loops can only be sinks but no sources. This is due to the fact that free Weasels only travel along the
main loop (they
follow the “outer” circuit track) and will only respond to requests from stations there.
In order for the Weasels to know into which secondary loop they have to move in order to reach a
destination, the stations must be grouped and the corresponding Turn marker for station groups must
be placed upstream of the exit into the secondary loop. All stations belonging to the same number range
of 100 units form a station group. The stations in a secondary loop must be stations of the same group.
Up to 10 groups may be defined.

Since every secondary loop must rejoin with the main loop, there are additional merge sections where
traffic control is required (provided that you use more than one Weasel). These merge sections are not
linked to stations. Simply use the markers Attention Entrance and Entrance of an unused station. The
Entrance marker should be placed in the secondary loop to avoid unnecessary stopping of your Weasels
in the main loop.
