Possible fast track for high-speed Caltrain?

The Chronicle reports today that Caltrain is working with the California High Speed Rail Authority on possible plans to speed up Caltrain electrification and improvements that would allow both faster commuter service and high speed service to run on the same line – possibly in just a few years’ time. (The article claims 2016.) If this happens it could be very good news for commuters, who have faced years of delays for the most basic of improvements to rail service.
