To all,
The Great Basin Lego Train Club (GBLT&C) located in and around Salt Lake City,
Utah is pleased to unveil our new LOGO ...
We based the LOGO on the 1970-1997 Rio Grande LOGO ...
GBLT&C has been functioning in one capacity or another since 2000.
In 2006 ULUG (Utah LUG) was created and merged with GBLT&C.
Since the merger both clubs have experienced phenomenal internal growth and
overwhelming support from the community.
In 2007, we attended 9 shows in Utah, Wyoming, Idaho and Nevada.
To date in 2008, we have attended two shows with 6 more shows scheduled and
another 3 shows in the planning stages.

Are you using the NXT on batteries alone, or using the Li-ion battery pack so
you can plug the NXT into a wall for more consistant power?

As others have noted, this has worked well with the RCX. It's essentially how
the GBC trains are controled (except there the entire track ends up powered by
RCXs, just multiple RCXs with multipl segments per RCX :-) ).

Have you looked at this?

I don't think anyone has ported LDDC to the NXT... yet... but i would think that
any solution that worked with the RCX (like direct-powering the trains, at least
small ones) would work with the NXT only perhaps better (the 500 mA limit being
raised on the output ports).

I'm not sure if there's a better way, and I haven't tried it with an NXT, but
I've had good luck with option 2 using an RCX. I isolated the track by putting
a bit of clear tape over the ends that connect to the other track sections.
