After only one weekday back in service, all Muni light-rail trains are going offline again for at least several weeks following an equipment failure on Monday, and a worker in the Muni Metro control center testing positive for COVID-19.

As of Saturday, August 22, Muni riders have been getting to see how some major changes are working on the Muni Metro train lines — and Monday morning all the new signs went up erasing the K and L lines from core-tunnel stations.

The SFMTA just announced that it will be boosting the frequency of buses on eight of the "core" transit lines currently in operation, in order to increase the ability of passengers to socially distance themselves from each other.

The SFMTA is undertaking another week (or so) of maintenance on the Muni Metro later this month, and this will mean no underground service for commuters leaving the office late or anyone trying to get home after dinner by train.
