The agency said 347,322 people rode its trains the day of the marches. The system was jam-packed that day, riders say, despite the agency putting extra trains into service.

That Saturday ridership is surpassed only by the crowds that poured into stations on Feb. 6, 2016. BART says it recorded 419,161 exits that day. Passengers thronged to Super Bowl City in downtown San Francisco, a Warriors' home game at Oakland's Oracle Arena and a Metallica concert at AT&T Park.

In other BART news:

Waiting for Warm Springs: Like you, we're wondering when BART's extension from Fremont to Warm Springs will open. The agency said it hoped to begin service in the fall. Autumn came and went as workers upgraded electrical infrastructure and wrestled with computer hardware and software problems. The latest from BART spokesman Chris Filippi:

At this point no opening date has been set. Yes, some of the electrical cables to Warm Springs had to be replaced. Also, as you mention, there have been problems getting the new software to communicate with our current aging computer system. Progress is being made but there is still more testing to be done before we can be confident that the new station is ready for revenue service. Once the testing is complete, then we will also need state approval to open Warm Springs.

Waiting for the Fleet of the Future: Like you, we're wondering when we'll get to see the new generation of BART cars running on the tracks. And yes, we'd like to ride on them, too. Agency officials said in October that they hoped to have the first 10 cars (of a potential order of 1,081 cars to be delivered over the next five or six years) ready to roll by the end of 2016. First, they'd be operated on BART's "main line" -- its regular tracks. And then at some point in early 2017, BART would give manufacturer Bombardier the high sign to begin full-scale production, and those first cars would go into regular passenger service. Here's where we are now, according to BART's Filippi:

The first 10-car train has been delivered and it is being tested on a regular basis on our mainline during the overnight hours when we are not in service. Once that testing is complete, we will tell Bombardier to start production of more cars. We do not have a firm date for when the new cars will begin revenue service. We should start getting additional new cars later this year.

Waiting for BART's next board meeting? It's scheduled for 9 a.m. Feb. 9 in the BART board room on the third floor at 344 20th St. in Oakland.
