I have just glossed through this topic, and maybe I missed something. My question to Don is:

Why are you trying to do this project the hard way, and reinvent the wheel?

All the software you need is already developed. It's called JMRI, which stands for Java Model Railroad Interface. It's free (no offense Harvy).

Why are you trying to detect off the center rail?

You have virtually free detection, as long as you are using a brand of track with the outside rails aren't electrically connected, think Gargraves, Atlas or MTH Scale Trax with a diode and a capacitor would do the job.

I'm sorry I didn't say all this at the beginning, six months ago. Probably would have saved you a lot of time and money.

None taken, Big Boy.  I would jump at the chance to do something for free.
