Looks cool.
I was investigating your automatic switching track setup, and have a question.
In the picture where "B" is in the common section, and "A" in the inner track,
the bottom switch would be "straight", because "B" set it as it passed. This
means only the inner track would be live, however when "A" switches the upper
switch to the outer track, both would be live, and "A" would continue. It'd be
a race to see whether "B" reaches the second sensor before "A" reaches the top
switch.
I think the bottom sensor only needs to set the top switch (to inner track),
but the top sensor would need to switch *both* to the outer track for this to
work.

Thanks for your comment Ross. I actually built the setup that I show on my
site in order to test if everything works alright... and it does.

Nice compact design with hardly any hard-to-find parts. Only problem is it
won't work for me. Maybe you opened your switches and trimmed the tab off,
so they would slide more easily?
With unmodified switches, the white gear engages before the switch is thrown
(for me, at least). Any suggestions?
Also, two design suggestions:
1) Extending the axle from 3 to 6-long allows you to put a visual indicator
on the exterior of the housing, so you can tell which way the switch is
thrown from far away.
2) The piece with the built-in rack is the piece I have the least of. You
can use the same piece without the built-in rack, and just add a 1x4 rack
piece. Then build the base up by one plate so it will fit under the gear.
Nice design though (if I can just get it to work!)

Nope, I've made no modifications to any parts... It would be like cutting my
own flesh!

Hmmm... I haven't experienced this problem (yet). I used a relatively
new/unused white gear so perhaps mine doesn't slip too easily? A problem
that might occur when you use the RCX to control the switch, is that you use
a power setting that is either to high or to low. If it's too high the white
gear might kick in before the point has a chance to throw. When the power
settings are too low (or batteries are weak) there may not be enough
traction to throw the switch.

Thanks for the input!

I notice that there is a Force (or Power, Resistence...) rating on the side
the white gear. Are they all the same or has LEGO made different ones? When
I tried using the white gear (in many different configs) I could never get
the gear to throw the switch (oh sure after much gear reduction maybe...).

I don't think so...

I think I found a possible explanation for why It didn't work for you guys.
It has something to do with the way you connect the 1 x 4 Liftarm to
the switch. Look at this:
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=28898
I tried this at home and when I connect the liftarm to only one "pin" it
wouldn't work. I always have it connected to both pins and this works fine
for me.
I hope this solves the problems you are experiencing.

I sued the right way to switch point, but the point never moves, only white gear in rotation, I used a Battery box to test it, is it any problems?
BTW, does anyone know any other practical automated switch point else?

Could you tell me the part number of 4x6 special plate in your
instructions?
Which set include it?

I got mine from the 8479 Barcode Multi-set. I think
there is a similar one, in red, in the 5533 Red Fury
Model Team set.
cheers,

Yep! There you go!

I found this one has no enough power to pull or push switch point, why
can you use it in your case?
