zone".

Here's my fantasy: implementing prototypical ATC (Automatic Train Control)
signalling with sensors (e.g. counting coupler magnets, as the best functional
equivalent to axle counters) at block boundaries to detect block occupancy, and
IR beacons at signal locations to stop trains if/when necessary. Control would
happen with NXTs. For simple operations (automatic stop and start at signals)
one could devise simple microcontroller-based beacons that broadcast a "go"
signal (a given speed step and direction) when given an input and a "stop"
(speed 0) signal otherwise.

I'll try this out some day if I manage to gather up enough LEGO. For the time
being, I'll keep dreaming... (My trains are the eighties grey-rail 12 V type...)

Followups set to .trains.

(...) I'd be very interested in that experiment (using a Hobby train RC on the PW Receiver) as well, but this does answer a number of questions for trains. For instance, tunnels and large layout out of line-of-sight on the RC should now be possible. (...) (17 years ago, 26-Jan-08, to lugnet.technic, lugnet.trains, lugnet.robotics)
