Much to my dismay, Caltrain will be ceasing weekend service for two years (two years!) in April. During that time they will be adding high speed rail lines. Two years is long enough for people to get out of the habit of using Caltrain to get into San Francisco for weekend. And it is a real loss for baseball fans who had a convenient way to get up to Giants games. Will the new express trains be worth the two year annoyance? For me, it depends on where they are going to actually stop.
