What my options on getting between San Francisco and San Jose?

Question

I am soon going to visit an event in San Jose, but due to too few connections to SJC, I decided to arrive at San Francisco. What are my options in getting to San Jose, most preferably the cheap ones?

Answer 1

You could take the BART (Pittsburg/Bay Point–SFO/Millbrae line) from SFO to Millbrae and catch the Caltrain from there to San Jose.

Here's a BART system map:

And a Caltrain system map:

The next cheapest option might be a SuperShuttle.
