Wind stability was a given reason back when it was planned to cross the Golden Gate Bridge, but that never happened
BART’s planning is basically a comedy of errors by aerospace engineers who specifically did not want to learn anything from other rail systems, hence the nonstandard car layout, the nonstandard electrification, the nonstandard wheels that make too much noise, etc. BART themselves clearly do not believe much of it anymore given that they operate a standard gauge line.
I recently visited SFO for the first time and loved the transit system - although the noise level of BART seemed… excessive.
Really stood out in the trip from the airport it was significantly louder than my flight. I was worried I was losing my mind, thanks for confirming that it’s real.
I used to ride BART 4-5 days a week, through the Transbay tunnel. I frequently got the "sustained loud noise" warning from my watch, notifying me that the combined duration and intensity of the ambient sound was enough to damage one's hearing.
