The only issue with Ross switches you need to know about is running Lionel Post war engines and operating cars with slider shoe pickups through Ross Switches. The design of the Ross Switch will cause the engine / car to uncouple when the slider shoe crosses the center rail of the switch. Operating cars with slider shoes will activate when going through a Ross Switch. Jim Barrett has a fix for this problem in one of his back shop videos. It involves filing back the slider shoes, and insulting the car body from the track ground.
