I've been playiong with that as well. The GBC trains that Steve & I have used
have a small 8-wide section under the baseplate, made out of 2x2 cylinders. That
way they mechanically toggle sensors (or in some cases power sources) at the
loading/unloading stations. I worked out a sensor (light+touch, so it only uses
one RCX input port) that detects any passing train as well as signialing if it
is a GBC train. The idea was I could run the GBC train into a "normal" layout,
sharing a track with a "normal" train... but being switched out to a GBC siding.
I prototyped it with two trains and a single loop with a siding, and it worked
for a couple of hours without faulting. I just have to re-do my
loading/unloading stations and software.

Thank you! So it uses a standard LDCC RCX and just talks from a "normal" RCX
to it via IR? I keep hoping for an "extended" firmware, that can support normal
NQC programs as well as handle LDCC style output. That way I can use the full
automation ability of the RCX, and control lots and lots of trains/accessories.
I've been thinking about this with the NXT as well... OK, *I* can't do it,
but I can suggest the idea to those who can. Since the NXT can drive
higher-powered motors, it might be able to pump out more current... as well as
having an actual LCD screen to work a user interface on.

It sounds like it would - if it's just a series of standard NQC routines to
send the proper IR signals, it should be easily portable. Now the question is if
I should/can install LDCC on one RCX, and start hacking my motors.
