3:01 PM Muni tells us that “the problem below has cleared and all Muni Metro lines in the subway have returned to automatic operation.” and that “Minor residual delays will last until the lines resume their normal schedules but the afternoon commute is not expected to be affected.”
12:22 PM: Muni has alerted us that all Muni Metro lines (that is, the J, K/T, L, M and N lines) are “experiencing rolling delays in the subway because of a problem with the train control system.” Alarmingly (or perhaps not?) “all trains are operating in manual mode.”
