It is just a matter of time before two trains are competing for
track controlled by the single module.
The next hint is how the double gapping is achieved. Many
modelers get almost anal-retentive on getting the rail joiners
directly across from each other. While this is an esthetic thing
for conductive joiners, it is counterproductive when providing
insulated gaps for auto-reversers.
If gaps are directly across from each other, the auto-reverser
may be confused. If the wheels hit the gaps at slightly different
times, the auto-reverser may sense the first short and reverse
in time to catch the second short. The short may persist long
enough to shut down a circuit breaker. Staggering the gaps
makes it such that the first wheel to hit a gap activates the
auto-reverser. It will be a bit of time before the opposite wheel
hits the second gap. No problem.
