I've got almost all the track completed along two of the walls which is 48 feet of shelves. Did a lot of running trains today, switching the spurs, run-arounds, all that, and I am loving the electromagnets and the turn-out controls. I would guess I am seeing about a 95% success rate with the uncouplers, both the electromagnets and the permanent magnets on the spurs. I found a couple of cars that are not acting properly, I'll have to adjust them. Also having very few, almost zero derailments. Good stuff.
