I don't actually have trains with anything but the toy can motors. Although not all are that tiny. No pitmann sized like I knew from the 70s and expected in at least a couple, my choices went from open frame to crap real fast. The only saving grace is it should only cost $15-20ea. (I last paid $12 for the size at a pricey brick & mortar about 2014 because it was there. I could have got it for $5-8 online.)
