CalTrain is one of the oldest rail systems on the West Coast, beginning service in 1864. It wasn't until 1985, however, that CalTrain adopted its current name, and since then, ridership has boomed. Daily weekday ridership on CalTrain now reaches nearly 80,000, up an astonishing 71% since 2010 just seven years ago. CalTrain runs from San Jose to San Francisco, stopping San Jose Diridon Station, a major transfer point for riders in the South Bay. CalTrain has direct bus connections to San Jose International Airport and Levi's Stadium, as well as direct connections to SAP Center, AT&T Park, and BART at Millbrae. CalTrain has a rich history, and it looks to continue its environmental impact reduction with possible future electrification of the system.
