The Fuzzy World 3um

Ok, two questions for those "in the know" at the WSOR. 1, is there any systematic numbering system for industry tracks around the WSOR system?

2, I am working on a project in Google Earth, basicly mapping the entire WSOR system. I am having trouble with the track numbering for the Madison Yard. Here is what I have so far:

http://maps.google.com/maps/ms?msid=202104883178660320092.0004a2cc0bfbd70e71a99&msa=0&ll=43.101422,-89.352064&spn=0.026572,0.054932

Here are the tracks I need assitance with: 105, 106, 107, 108, 109, 123, 400, 401, 405, 406, 600, 601, 602.

Any assistance would be greatly appreciated, thanks in advance.
