Although Caltrain (CA) runs service in the heart of Silicon Valley, arguably one of the most wired parts of the county, passengers do not have the advantage of WiFi connectivity during their commute. But pressure is building for Caltrain to keep up with its neighbors like the Santa Clara Valley Transportation Authority, which offers free 4G wireless on its light-rail network, and the Capitol Corridor Intercity Rail Service, which will have wireless systems on all trains by the end of the year. Grassroots coalition Friends of Caltrain urged people to sign an online petition asking for WiFi and the Silicon Valley Leadership Group, which represents local businesses and employers, supports WiFi as well. Caltrain is not exactly opposed to providing wireless connections, but the agency’s budget troubles are delaying any decision. “We think WFi is a great idea, but right now our efforts are concentrated on keeping the service that we have,” said spokeswoman Christine Dunn.
