Berryessa/North San Jose to Embarcadero StationTaking BART, he noted, is also faster than driving the highly trafficked highways into San Francisco. “Being on BART makes me feel relieved. It's way more stressful driving,” he said.
Q: Why doesn't BART run 24/7 or at least later on Friday and Saturday nights? A: The short window of time when BART isn't in operation is used for essential nightly track maintenance to help keep BART safe and reliable.
Hours of operation are generally from 4 am to midnight on weekdays, 6 am to midnight on Saturdays and 8 am to midnight on Sundays and major holidays. Individual station closing times are coordinated with the schedule for the last train beginning at around midnight.
When it rains, BART also alters its computer programs to slow the acceleration of trains in certain areas to prevent them from spinning their wheels. But those delays, he said, are typically less than 30 seconds. It's nothing that would be noticed by passengers, he said.
BART actually has a big machine that grinds down the bumps on corrugated track, eliminating some of the noise. This explains why sometimes a portion of the BART system makes loud uuunnnhhh sounds one day and doesn't make a peep the next. You aren't crazy -- they just smoothed out the track at night.
Earthquake Safety ProgramThe 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.
In celebration of BART's upcoming 50th anniversary on September 11, BART is offering a 50% discount for the entire month of September 2022. The reduced fare will be automatically deducted when using Clipper at the fare gates.
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.
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.
It goes through an immersed tube, the Transbay Tube. The tube is made of two tunnels for trains, and a gallery which people can walk through, in case, say, a train derails. The immersed tube was built on land, and submerged after. It opened on September 11, 1972.
In San Francisco (and some other cities), BART stations are underground, so you'll have to walk down the stairs or take the escalator down into the station. In other cities around the Bay Area, most of the stations are above ground. So you'll have to go into the station at ground level.
Perhaps ironically, the Blue Line takes several points of pride from its proximity to water, which gives it its name. Local historians claim the tunnel that runs under the harbor as the first underwater subway tunnel in the United States.
BART (Bay Area Rapid Transport) is similar to a short-distance train system, and the BART lines link San Francisco to other cities and further away places. The network is used by over 400,000 people per day.
