Yeah, that'd be great if you could share (padmapper at gmail). I started recreating the google transit overlay, but it's pretty nontrivial to make a readable subway map programmatically and I got sidetracked on other projects.

If there's no map link, it attempts to infer based on that other info you mention and classifies them as likely inaccurate. Frequently it's the map link that's wrong, since people often file it in re wrong sub-CL and CL seems to modify the map link based on that info.

I'd be really interested if there were aspects you liked (or didn't like) about the others you tried.

Thanks!
