I’ve started this spreadsheet (read-only link; you can save and edit as you like) of mostly strong pro-rail boxes in 2000 (basically central Austin, until I hit the part of town where it started to lose – so a few non-yes precincts are included for geographic completeness). I didn’t go as far south as some people would; I consider central Austin to stop at Oltorf and go no further north than approximately Koenig. I did include some of lower East Austin.
Screenshot sample here:

2000 results: http://www.centralaustincdc.org/images/Rail_2000.pdf
So far, it looks like in extreme central Austin alone, a margin similar to that seen in the 2000 election would have yielded around a 5600 swing in votes (2800 nos changing to yeses, essentially). This is not yet sufficient to change the balance of the 2014 election (margin was about 27,000), but it is clearly a major portion of the swing.
Some key notes:
I have excluded Mueller because nobody lived there in 2000, so we can’t assign a reasonable value for their margin. The “mostly Mueller” precinct went for by 64% (1580/2470) – if I was forced to guess how they would have voted on the 2000 plan, I’d say 70%+. I also excluded one precinct on Auditorium Shores where 1 guy voted.
The 2000 report only has ranges for precinct margins. You can change the assigned value for each range in your copy of the spreadsheet if you want. I chose 75% for the “over 70%” boxes, 65% for the “60-70%” boxes, etc.
The precincts do not line up exactly. A few shifted boundaries, some were combined, numbers changed, etc. I have noted which precincts in 2000 I considered the most relevant for 2014. Again, you can save the spreadsheet yourself and change this if you wish. If more than one 2000 precinct was used for comparison, I averaged their assigned values first.
Will pull some interesting nuggets out of here later today as I get to them. I’m sick as a dog and at my kid’s chess tournament all day today, and my battery in my phone, being used for access, is dying fast.
