BART completes $1.5B earthquake retrofitting project of Transbay Tube, system
Briefly

"The Transbay Tube now has a stronger steel lining," said BART General Manager Bob Powers. "It has a more powerful and robust pumping system that will protect itself against even stronger earthquakes, the type of earthquake that is projected to occur only once in 1,000 years."
BART spokesperson Jim Allison noted, "One of the predictions is if there were some sort of earthquake that was very, very powerful, there could be small cracks that could create some minor flooding and so this pumping is designed to remove that flooding."
