That is an excellent system for controlling train crossings. I love that it is all above the baseplates and only uses one motor for both crossings. I have two suggestions for the motor timing on raising and lowering of the gates: 1) Use a Technic (...) (16 years ago, 6-Sep-08, to lugnet.trains)

This system is used 4 RCXs to control 2 trains, 1 car and 1 level crossing. RCX1 is used to control 3 switch points and response 3 light sensors. RCX2 is used to control 3 segments track and response 2 light sensors. RCX3 is used to control level (...) (16 years ago, 6-Sep-08, to lugnet.announce.moc, lugnet.trains, lugnet.robotics.rcx.legos) !

(...) Thanks, Matt. The real tricky part about it is in connecting the 2x3 slope on it's side. Because of the way it must be done, I originally ended up with a slot/gap between the top of the 2x3 slope and the brick above it. The slot/gap was about (...)
