What's inside the new Central Subway!

Muni chief Jeffrey Tumlin offers Total SF a tour of the new Central Subway Union Square station and answers questions, including when (after a three-year delay) it might be open for passengers. Total SF hosts Heather Knight and Peter Hartlaub also talk about the art installations, Rose Pak, whether the station is haunted — and the importance of the new Prop A bonds on the ballot, with some of the new subway being controlled with software that still uses floppy disks. Produced by Peter Hartlaub. Music is "The Tide Will Rise" by the Sunset Shipwrecks off their album "Community" and cable car bell-ringing by 8-time champion Byron Cobb.
