Update as of 2:15 pm: A computer router failure caused yesterday’s BART shutdown. That’s according to BART spokesperson Linton Johnson. The routers send information about the trains from the side of the tracks to the central computer system. There are two routers and in the case of a failure, one is supposed to take over for the other. But both of them failed last night.
Johnson says BART officials are still looking for the root cause of the failure. But in the meantime they have backup computer staff on hand. And they know the interim fix for the problem if they both go down again.

Meanwhile... Monday evening's hour long outage of BART's control system generated a whole lot of anger online.
Perhaps it's good then that BART is actually readying itself for a big upgrade. This Thursday it's kicking off a series of open houses where you can look at the Fleet of the Future (see above).
The new fleet was designed along with a BMW design team. According to the Bay Citizen the new cars will also have easily cleaned, wipeable seats. Good thing, that was a big deal to people who took part in this seat "taste test."
