Yes, that is correct. The electrical contact is not made by the switching
section of rail. I doubt you would cause any damage to the motors - any
damage would be to the controller. They seem to be pretty tolerant
electrically, but as Lar said, continued shorting, even if momentary, may
eventually cause damage.

I’m not a big Train-head, so I’m trying to figure out where the problem is from
various bits of this discussion. Is the problem that one pair of wheels is
connected to power flowing in one direction and the other is connected to power
flowing in the other direction, or is it that one pair of wheels is under power
while the other is not? If it’s the former, the short leg between the A and B
points shouldn’t be charged at all until you manually switch the A point, right?
If it’s the latter, maybe you could get away with setting the B point to curved
and building a manually activated gate that will switch it to straight after the
entire motor bogey has passed through it, thereby cutting the power to both
wheel pairs at the same time.

So when one axle has traversed B to the short section of track, the power pickup will connect the outside rail right through the loop, shorting the controller. (...)
