You can use Scout to control trains like using RCX, I had tested. The difference is that Scout only can use passive light sensor, then they only have two input and output ports, then you only can use NQC, not legOS. When you write NQC, you can use __RCX, __SCOUT and __RCX=2 for different parts of your program. If you use RCX/Scout to control tracks not trains, you don't need so many RCX/Scout, separate your layout to blocks, then one block is connected to one output port of RCX/Scout, this way is better than putting RCX/Scout on the train, because you don't need to modify your train. Good luck! Zhengrong David Niemann wrote: > Hello all, > Thanks for your help. I am back with more questions.

One Addition for Scout, you can use a fiber cable to connect Scout and a micro-scout, let that micro-scout to control a switch point, so you can get three output ports from Scout. Then if you can put Scout on a special position with a external light (...) (25 years ago, 31-Oct-01, to lugnet.trains, lugnet.robotics, lugnet.robotics.scout)

(...) With the Scout (or RCX for that matter) you can use a phototransistor as a light sensor for the scout. Put a light or IF emitter on the other side of the track and it can detect a break in the light. You can count cars or anything you want. It (...)

Hello all, Thanks for your help. I am back with more questions. First, is it possible to use scout computers like the one in this auction (URL) control trains instead of the RCXs?
