The first is the California High Speed Rail blog.  Written and run by Robert Cruickshank, it played an important role in the Prop 1A campaign by providing both a place for discussion and a source of good information about the benefits of the project, statewide and local.  It’s now moved on to ensuring HSR in CA keeps moving forward – passing the bond was only the first step.

The second is blog is rather new.  The Caltrain HSR Compatibility blog focuses on the integration of HSR into the existing Caltrain right-of-way on the peninsula.  So far, it’s taken the form of a series of case studies on particular sections or stations of interest.  There’s a ton of good information there.  The author, ‘Clem’, is clearly very knowledgeable about the Caltrain right-of-way, its stations, and the operational requirements of HSR.
