This morning, Streetsblog got a private tour of the two subterranean levels of the Transit Center--the future train station mezzanine and the train platform level below it. Photographs can't really do justice to the breathtaking scale of the facility, which will some day house both Caltrain and California high-speed rail. But when you walk through the grand hall and other street-level parts of the new transit center, here's a look at what's below your feet:
Location of future escalators from the mezzanine level down to the platforms to catch Caltrain and high-speed rail
Natural light will get all the way down to the tracks via the 'oculus' skylight that stretches through all levels of the facility. There will be more retail on the mezzanine level, and there will be a direct pedestrian connection under Beale Street to BART and Muni at Embarcadero. And as previously reported, the powers that be are nearly finished hashing out details on the train track alignment from 4th and King to the Transit Center.
The first trains are scheduled to arrive no sooner than 2026. More pictures below.
It looks like a nuclear reactor but it's actually the bottom of the oculus--the skylight all the way from the park at the top of the center to the lower level of the train box in the basement

The giant turn from the platforms to where the downtown extension tunnel will start. This is the slot for one of the six tracks

It may not look like much, but this spot on the ceiling is where the future escalators will lead up from the train mezzanine to the grand hall
The area of the floor in the grand hall where escalators will go down to the train station level--notice no detailed artwork here, since the floor will be cut open in a few years
