Nice job. I am planning the same on a few myself. I think I will use the Drive wheels instead of the trailing truck just to ensure four chuffs with the drivers in the same position each time. Don't get me wrong, your upgrade is a great improvement. It's just one of those things that bugs me personally. You seem to be getting 3+, but not quite 4 there. But again, that's just my bugaboo. Great job. Where did you get the reed switch and magnets?
