Caltrain works very well if you want to go quickly from San Jose to points north/west. VTA's light rail lines have some quite fast sections south of Downtown San Jose. Together, they could make a rapid transit network that can take transit riders all the way across the county quickly, in the way that freeways do for drivers. But the connections are often poorly timed, especially between the Caltrain and the Santa Teresa branch of the light rail, especially on weekends when there is no Caltrain service to Tamien. By timing transfers (and advertising them well) you can take these separate lines and make something greater than the sum of its parts. Also, Caltrain should be considered part of the VTA system within the county and should have fares charged accordingly.
