I've wondered what the yellow raised line down the middle of Palo Alto Transit Center was supposed to mean! Unfortunately, I think it stops around the time it reaches the steps to the train station. On the other hand, San Jose Diridon doesn't have tactile paving, but it does have some sort of "talking sign for the blind" things telling you which paths to take, and where to stand!
