It turns out that Transbay Blog does not excel at taking vacations, since we posted even during our “hiatus.” But in light of the interesting developments that are in store for 2009 on the local, state, and federal levels, this site is returning from hiatus, with the caveat that posts may appear on a somewhat irregular schedule. To make up for somewhat spotty posting during the past couple of months, here is the second installment in our series of track maps, this one focusing on the South Bay; I will probably add more details in the future, so you might consider it a first version. The image at right depicts the intermodal Caltrain/VTA station in downtown Mountain View, extracted from the map. San Jose and its environs possess quite a bit of track used for commuter rail (Caltrain, Capitol Corridor, ACE), freight, and VTA light rail. The map depicts track used by these various systems, with a focus on passenger rail, but select freight track is included to call attention to certain features. The map also includes potential track for the planned BART and light rail extensions, marked lightly in gray so as to not infringe on existing track that is more boldly colored. Since VTA has formally announced its intention to pursue the BART to Silicon Valley extension at the expense of all other Santa Clara County transit projects, we will probably not see both BART and new light rail any time soon. Nonetheless, the extensions are included to illustrate how they connect (or don’t quite connect, as the case may be) to service currently in operation. The map is high resolution and there is quite a bit of white space in places where track is sparse, so you may want to scroll or zoom around to catch the different sections. More detailed notes are included on the map itself, which you can click here to view.
