Don, I'm still having problems with my old train engine. It is getting power, but the part that is supposed to spin does not spin. It moves freely when I use my finger. I cleaned and oiled the gears. At this point I don't know if it is worth spending money and time on or just get a new DCC engine. But I would at least like to get in touch with your contact who replaces old moters with new, more efficient ones.
