Loop problems
At the loop points in two-rail-systems, different polarities meet with
each other. As soon as a vehicle bridges the differently polarized
sections when driving in or out the terminal loop a short circuit occurs.
In digital layouts loop modules generally have to adapt the polarity
within the terminal loop to the one outside. In case the polarity outside
the terminal loop would be altered, different polarities would meet at
the transition to the next booster section. Thus the problem would be
dislocated only.
