Multiple BART Lines Shut Down Sunday

Bay Area Rapid Transit ran reduced service on Sunday, April 26, suspending the Red and Green lines for all-day work in the Transbay Tube. (bart.gov) BART said trains were limited to one track through the underwater tube between Oakland and San Francisco while crews performed essential lighting work. Systemwide frequency dropped to every 30 minutes. (bart.gov) (cbsnews.com) Only the Blue, Yellow, and Orange lines operated Sunday. Riders from Berryessa were told to take a Richmond train and transfer at Bay Fair to reach Daly City service. (bart.gov) Millbrae-bound riders were told to use the shuttle train between San Francisco International Airport and Millbrae, then transfer to or from the Yellow line. The Red line did not run at all. (bart.gov) (kron4.com) The service changes were temporary, with BART saying normal service would return Monday, April 27. Sunday service hours otherwise remained 8 a.m. to midnight. (bart.gov 1) (bart.gov 2) The April 26 disruption was part of a larger construction push inside the Transbay Tube and on the San Francisco airport extension. BART has also warned of 30-minute late-night delays between Millbrae, SFO, and San Bruno on Sunday through Thursday nights through summer 2026 for train-control modernization. (bart.gov) BART had flagged other single-tracking Sundays for the same tube work, including April 19 and May 10, with the same 30-minute headways and Red and Green line suspensions.
