Hi Carl,
I tried some time ago, way before the mindstorms, to use read contacts. The
magnets of the wagon/engines will close the contact each time they pass.
I guess that the RCX can see this as 0 and 1. With this you can, I imagine,
count the length of your train. This allows you to take different action
for different trains.
Hope it works,
Guido
