quite neat. I hope you can figure out the correct switching delays for the micromotor. Do you think this technique could be used to make a monorail level crossing ? Steve (16 years ago, 11-Sep-08, to lugnet.trains, FTX)

I managed to snag some rare dark red brick from a grab bag at the local Lego store. The dark red pieces are from set 7665 (Republic Cruiser). I then combined them with some extra train parts and you get what you see below. The end result was this (...) (16 years ago, 9-Sep-08, to lugnet.trains, FTX)

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) !

(...) break at some point, but you seem to have a pretty good system there. (...) Actually, I think you could do this at least partially with a single sensor. If the train is running at a fixed speed, you can have the program figure that speed out (...) (16 years ago, 5-Sep-08, to lugnet.trains, lugnet.robotics.nxt)

(...) 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 (...)
