You're Really, Really Curious About BART

We get a lot of BART questions from our listeners, so this week we're answering a slew of them with long-time transit reporter Dan Brekke. How did they build the underwater tunnels for BART? In its nearly 50 years of existence, why has BART taken so long to extend into Santa Clara County? And only normally protruded into San Mateo County and never expanded into any of the North Bay counties? Why are there news kiosks in the BART station that are closed? Why doesn't BART let people run these news kiosks? What is the history?  At the West Oakland BART Station there are ads right next to the third rail. How on earth do they change those out without getting electrocuted? Why does it seem like the escalators are constantly broken? Why does BART announce elevator status all the time? Our question askers this week were Briana, Brad Meyer, Jay Quigley, Mark, Dan and Eric.  Additional Goodies Why are BART trains so loud?
