My apoligies for posting this again, but my original post appears to be locked so I cannot continue the thread.
Originally, I asked for help to resolve an issue I was having with MTH Real Trax. There are two places (0-31 MTH Real Trax curves) where I get a sizzling sound and some sparks when my engine passes over. I tried a second engine on the tracks and have the same issue. I received some good suggestions including cleaning the tracks, checking the connectors and ultimately replacing the sections with new tracks -- all of which I have done. Unfortunately, I still have the issue. It's possible I replaced the sectiosn with more bad track and may purchase another four curve sections to to be sure, but is there anything else to look at with this?
Thanks.
