If you still have false trigering then it was because of either the magnetic coupling or possibly vibration.

At least that is what it seems you were getting at with your suggestion (or am I missing your point Mark?)
Dwight,

Yes, just move the reeds temporary to see if they are triggering. If that is causing the problem, maybe just by rotating the reeds 90 degrees would solve the problem? Abecker made two statements that are key - "It worked superbly on the bench" and installed with the reeds disconnected, it quit triggering. So it's probably interference entering the cable or the reeds closing?

Abecker should take note when it is triggering. On acceleration the motor will be drawing the most current. On deceleration it could be generating inductive spikes back into the power supply. Does it false when the train is not moving?

Brings back memories, my dad had a large H0 gauge train table when I was a kid. We couldn't wait for him to get home from work
so we could run it.
