I am retired but I feel like a child because I have really gotten into trains about a year ago. If there are others out there like me, let me tell you about the importance of clean tracks. I have a MTH trolley that stopped at a particular point on my layout every time and then moved again after a while. I thought I pushed some program button and spent hours reprogramming, doing electrical continuity checks, checking track voltage. Everything was fine. Tightened all the tracks. Then, decided to clean the tracks. DUH. It worked. Everything is now good.
