Oh yeah that water tunnel is quite cool, esp the structure they built across the hayward fault, i think it can allow 8.5 ft of slip along the fault without breaking the water pipe. Its one of the main sources of water to the east bay (theres a backup tunnel under kensington called the san pablo tunnel)
@@ezrakainz Yeah I meant the BART tunnel that you go through between Orinda and Rockridge stations. I remember reading somewhere that it also has a special slip joint where it passes through the Hayward Fault. Would love to know more about that.
One night in 2007 I was on a BART train from SF to Oakland. We left the last station in SF and traveled for about 20 seconds before the train came to a complete stop. A few people on the train were alarmed by this. A few started to hyperventilate. One woman lay down on the floor. The train operator voice came on: "Ladies and gentlemen... we have just experienced a minor 4.5 earthquake. We will continue our ride into Oakland at 10 miles an hour in order to inspect the track ahead of us." It took 6 times longer to get to the first stop in West Oakland.
The Transbay Tube is about as old as George Lucas' "THX-1138" film, starring Robert Duvall as the titular character. In fact, THX-1138 was filmed in parts of the Transbay Tube before it went into service in San Francisco. Per Wikipedia's entry for THX 1138: "The under-construction Transbay Tube served as the tunnel through which THX escapes". I think BART was already operating on the East Bay by then.
"But the most interesting bay crossing isn't one you'll see in postcards or in the movies" Reminder that the final scene in George Lucas's THX-1138 was filmed in the incomplete Transbay Tube, so you can actually see the tube in a movie.
@@AlvaSudden Usually by media. The USGS hasn't used it for a few decades now. They use the Moment Magnitude scale, as the values are pretty similar, but it gives a lot more accurate information. From the USGS website: "The Richter scale is an outdated method for measuring magnitude that is no longer used by the USGS for large, teleseismic earthquakes. The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes."
We need a longer documentarty!

I have a fascination for undersea crossings like the channel tunnel, seikan tunnel, faroe island tunnels, and especially the trans-bay tube.
This is fascinating. Would love to see a similar video about the Berkeley Hills tunnel between Rockridge and Orinda

Oh shoot i forgot bart also has a tunnel there, i think they have a similar structure as well

This is a great video. I've been showing it to my friends where I worked the last few years. I worked on the controls of the pump system in the tube.
Thank you for your service!
I love the tube. I loved seeing the old 70's images too. Big thumbs up. 🤓🤓
Thank you engineers

And it would also make for some unique BART merch... wink wink?
Very interesting vid. I learned something new today.
Sweet!
We need a footage inside the ocean transbay tube. 👍
Great Video!
You forgot to mention THX 1138. That was one movie filmed in the tube.
Thats crazy
BART, that tube was used for George Lucas' film from 1971 THX-1138.
the video should include some howling ghost sounds from a legacy train in the tunnel.
nitpick: We haven't used Richter in 40 years
Huh? I hear Richter scale used all the time.
