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.

To all,
I would like to find a way (simple way that is) to power our LTC 9v trains using
both the standard LEGO 9v train modulator and the NXT.
We have attempted the following:
1- Power the train simply using the NXT and the converter cables. Too much
battery drain during the show.
2- Isolate a section of track via a switch and power the train via a converter
cable only when the train is on the isolated section. This has probably been
the best approach.
3- Attached a servo motor to the 9v modulator and then programmed rotations from
the NXT to the servo motor to determine speed. There was much difficulty
attaching the servo to the modulator.
Is there a better way?
Thank you,

The show was a success! In the end only Reed and I were able to attend.
Attempting to set-up and take down a 10 table lay-out with only two people
turned out to be quite a task! We were exhausted but well rewarded by the
enthusiasm of the show attendees.
The Idaho Falls show is well run and we are treated very well as a LUG.
