This actually makes sense. The length of static rail needs to be
long enough to give the AR response time. Simple enough at

This got me thinking further (always dangerous, I know).
And I'm getting to the point of view that even 1 cm should
suffice. Because the two gaps will not be straddled
*simultaneously* - or if they are, that's only after the first
one has done its switching, so it's harmless. Meaning there
will be no fight between the AR-units, as one will switch

I had never thought about how long the fixed polarity section
needs to be until this week. I proposed that the length of
the longest locomotive or lighted car should be enough. If
you were really strapped for track distance, the length of a
powered truck should also be fine. I just propose as long as
your longest locomotive so that you don't have to worry about
which wheels are power pick up wheels.
