Dan,
Very clever layout. How is the RCX deturning when to let the next train go? Is
it timed or is it using a sensor to figure out if the track was clear. I would
be curious to see how this worked with longer trains, ones with a few pieces
of rolling stock.
The issue I ran into with my non-LEGO controled layout was the the light
sensors were detecting the gaps between cars and assuming the the coast was
clear when it really wasn't. So I ended up setting up parameters that said the
the light sensor had to be clear for a selected amount of time (aprox 5s). I
was wondering if you were able (or did) anything like this with your layout.
