According to the San Francisco Municipal Transportation Association, the cars will officially be back in early September.
In August, passengers will be invited for "mock service" to test the cars before they return later in the fall.
The popular Powell-Hyde line will be the first to return.
REMINDER: Cable cars are returning to SF streets, but we are unable to accept passengers at this time while we conduct inspections & testing. Don't fret, though, as we'll be inviting riders aboard for mock service in August. More info in our blog: https://t.co/P2naTY9o2w— SFMTA (@sfmta_muni) July 12, 2021
