Update 9:30 a.m.

BART reports: “We are now open and offering limited service. There is currently no service from Daly City to Millbrae or SFO airport.”

Computer problems halted all BART trains at around 3 a.m. Saturday morning.

“BART crews working overnight on BART’s uninterruptible power supply in Oakland ran into problems that impacted our traction power supply system and train control routing system,” BART officials wrote on their website.

Without both those systems, “we are not able to safely dispatch trains for service.”

BART is “troubleshooting the problem to get both systems up and working,” according to its website.

That was news to Gabriel Ortiz, a 28-year-old, who had just gotten off work at the post office and was headed home to Oakland at 7:30 a.m. “I’m going to have to take an Uber home,” he said looking at the chain gate that had been pulled down at the entry to the 16th Street Station.

But he didn’t want to turn to Uber so quickly so he downloaded the BART App to look at his options.

“No delays reported,” it announced.  “Shit,” he said. “They could at least update their app.”

Jesus Torres was on his way to work at the Ferry Building when he walked down the stairs to find the gates at 16th Street closed. He just shook his head, took a photo of the closed gate and headed back up the stairs.

On his way up he headed by Shrimant Jaruhar, a consultant with two bags. He was off to India for a vacation and his luck of the day was that we warned him to go no further with those bags.

It would be Uber for him.

Note to BART: It might be a good idea to close the gate at the top of the station instead of letting riders walk all the way down to discover a closed station.

To riders, there is always  Trip Planner, but BART warns, “Just put in your starting point and destination and in options/transit options turn off BART.”

Bus agencies that serve the stations are offering free rides.
