I have an 031 switch, 45 degree crossover, and an 0-72 switch in a row. Sometimes I have problems with dead spots, but I'm too lazy or technically incompetent to eliminate the problem. So the proverbial "Hand of God" bails me out, or I lock the motors into forward.
I also have a Ross double crossover which causes real problems on the prewar
sliding shoes. I tried filing down the frog with a bit of success, but I decided to
stop running the cars over those tracks.
