Apparently I used too much of this stuff, and/or didn't wipe enough of it off the rails and the switch points. Coming back after a few years of non use, when I actually tried to run an engine, it didn't. Anywhere on the layout. I went around and wiped down the rails more then once then used a old 'track eraser' (unknown if it was a actual pencil eraser or what) the engine finally moved until it got to the first switch point where it stopped. The track is Peco. All, or most of the 'points' seem to be affective. My initial solution was to use spray "tuner cleaner" (as it use to be called when it was actually used to clean mechanical TV tuners from the 70's and before). I will add this was NOT any material that has any 'lube' in it, just pure, no residue cleaner. It mostly worked, but I still have a few points that are intermittent. Any other suggestions to help recover from this nightmare?
