OK, Thought I would give you guys an update, since you were so helpful. I replaced all of the remaining Fastrack with menards tubular track. I used CTC clip ons (3 of them) to connect power to track. The widest gap I have now between clipons is about 12 feet. I ziptied all the track joints together today. I haven't run continuity checks yet, but it is my next step. Train will run for a bit, then stop. If I switch it into reverse,(via the switch on locomotive) it often starts back up again, but only for a short while (60 seconds or so). I get intermittent overload light on transformer sometimes when train stops. I'm wondering if part of the issue isn't the locomotive now. I have never cleaned it, and to the best of my knowledge it has never been cleaned. Do any of you have any links to good "how to" videos on how to clean and lubricate a 6-8602 locomotive? Thanks again for all your help.
