It looks like September is the target date for wireless on Caltrain. This isn't as tempting as it once was as my Caltrain commute is a lot shorter nowadays, but there does appear to be a benefit for even those that don't crack open their laptops:
One side benefit is the technology may help Caltrain and commuters track trains using Global Positioning System, Caltrain spokesman Jonah Weinberg said.
I've always been annoyed that the digital announcement boards at Caltrain rarely tell you anything useful about the train schedule. Most often they show ads for Caltrain service; rarely they tell you when Caltrain will be late. If this would allow Caltrain to more frequently provide time estimates for trains, or if it would allow me to have an online tracker that could tell me when I needed to leave the office, that'd be fantastic.
