| | | I've seen info on Matt's train depot web site about automating switching rails. I would like to be able to control the motors from the speed regulator. I was thinking of using the 5120 Polarity Switch to do this. Any thoughts on this? Is there a (...) (24 years ago, 27-Apr-00, to lugnet.trains)

The RCX is running the train around a circuit in a loop, with inputs from touch and light sensors to determine train passage and location. Randomized counters keep the program from (...)
