Providing train service between San Francisco and San Jose down the middle of the Peninsula, the Caltrain is the cleanest and fastest form of public transportation in the bay area.
Baby Bullet service (only during commute hours) is faster than driving. Otherwise, bicycles are allowed until the bike car fills up (frequently during commute hours) and alcohol is permitted until 9pm.
Access to the SFO Airport is possible (via BART to Millbrae), and mostly useful for southerly directions since BART runs north.
Tickets must be purchased before boarding. If the machine isn't working, board the train and talk to the conductor.
