Important: A critical update to the 2012 Base Network has been uploaded to the website. This update fixes a problem with link lengths; namely, a handful of links were manually edited with the incorrect coordinate factor and ended up with lengths 10x what they should be. Draft 10 has the corrected link lengths, and Update 2 contains a script to fix this error. It also deletes Node 40445 in Mississauga which overlaps another node.
This script requires the latest TMG Toolbox (and will raise an error otherwise).
