What happens to old BART trains?
The majority of the old cars will be recycled. The Fleet Disposition Team will manage the process, including selecting which parts should be harvested from retired vehicles and choosing which cars with the highest failure rates get retired first.
Do they ever clean the BART?
Seats are scrubbed with hot water and disinfectant soap during a thorough clean. BART recently increased the frequency of thorough cleans from every 900 hours of train car service to every 450 hours, meaning we've doubled the number of times the cars in our system undergo a deep clean.
What happens to BART during an earthquake?
The BART server calculates the earthquake's seismic intensity within nanoseconds, and if the seismic intensity -- or MMI (Modified Mercalli Intensity Scale) -- is greater than IV, the server will automatically signal trains to reduce speeds. Trains then automatically begin slowing to 27 mph.
How deep is the water under the San Francisco Bay Bridge?
In many places, it's not much deeper than a swimming pool. In between Hayward and San Mateo, it's a mere 12 inches. Under the Golden Gate Bridge, however, the depth reaches just over 370 feet.
Which BART goes underwater?

Is BART earthquake proof?
Earthquake Safety Program The Transbay Tube is BART's most critical asset. Although the tube is structurally sound, in a very large and very rare earthquake, the outer shell and concrete liner are predicted to crack.
Is BART making money?
Factoring in these new state budget funds, assuming MTC commissioners adopt the staff recommendation in mid-November 2023, BART must now solve a $326M deficit before FY28. It was previously $678M. BART would then face and annual operating deficit of $264M starting in FY28.
Why is BART so noisy?
Like most trains, BART wheels are tied together with rigid axels and no differentials. This means the wheels always rotate at the same speed, even around corners. Because the inner radius is smaller, there is less distance to travel, which can cause a slippage between the wheels and track, which is noisy.
