The new Transbay Terminal just opened yesterday. Multiple local bus operators are already using the place. Online diagrams show Amtrak/Greyhound operating out of their own bus bays on the 3rd floor. On a nearby small space on the 2nd floor, there was a Greyhound waiting room (not open yet) and some adjacent spaces under construction, some probably for Amtrak. Curiously, buses accessing the 3rd floor have direct access on their own elevated road south to freeways and the Bay Bridge. I'm thinking Amtrak buses going to/from the terminal will have to go on an arduous loop around town to get to the other local stops in San Francisco (sff, sfw, sfs). The new terminal was massive (4 stories) and beautiful, with the top being an open air park. The 3rd floor has a whopping 37 bus bays, mostly used by AC Transit, and it took a good few minutes to walk down. Best of all, there were lots of people enjoying the place and riding the buses. I hope Amtrak starts operating here soon. I haven't found any info online as to when it'll happen, but Amtrak/Greyhound are already on some of the signage there. Years ahead, there are plans for an underground Caltrain extension to here. It sounds a bit far fetched, but if it happens, San Francisco will have a transit hub worthy of Japan or Europe. Too bad that BART is still 3 blocks away.
