I've never found any decent, up-to-date KMZs of the current route alignments, station locations, etc. (the Authority
really needs to put something like this on their site. Their current map isn't useful at all).
Anyways, I found an old
map based on one done by
some students at UC Davis, and imported it into Google Earth and created a
KMZ. I haven't yet imported it into Google Maps (because that interface is clunky, and the original data is from GIS so the projection is likely different and means it needs to be tweaked), but you can view it in the Earth web client.
If nothing else, it's interesting to quickly identify some of the construction sites/land clearing that's been taking place -- although, I'm fairly certain Google Maps may not have been updated since I last examined the route over a 1.5 years ago? I'm not sure how frequently this data gets updated.
You can tell it's not too old because the
Tuolome St. Bridge seems complete, but stuff like the Cottonwood Creek Viaduct, Cedar Viaduct, etc aren't very visible ¯\_(ツ)_/¯ ?
Anyways, if anyone has anything more recent/better, please share.
