San Francisco Muni riders on the OB subway line should expect slower service between Embarcadero and Van Ness stations Monday.

Switch Problem Resolved, Monitoring Continues

Track maintenance personnel responded to the switch issue near Duboce Portal earlier Monday, according to the transit agency. Officials said the initial problem has been fixed, but crews are staying on site to ensure safe operations continue. Switch malfunctions can affect train routing and speed through affected areas, requiring careful monitoring even after repairs. The agency didn't specify what caused the switch to malfunction or whether similar issues have occurred recently at this location.

Service Running With Speed Restrictions

The OB line continues operating through the affected segment, but trains are moving slower than normal between Embarcadero and Van Ness, officials said. The rest of the line is running at regular speeds. Transit officials didn't provide specific information about how much extra time riders should expect for trips through the affected area. The agency also hasn't said whether the speed restrictions will remain in place through the evening commute or be lifted sooner.

Timeline for Normal Service Unclear

Officials haven't announced when full-speed service will resume on the affected segment. The agency said crews will continue monitoring the switch to ensure it's operating properly before lifting speed restrictions. Transit agencies typically maintain cautious operating speeds after switch repairs until they're confident the equipment is functioning reliably.

Riders Advised to Plan Extra Time

Commuters traveling through the Embarcadero to Van Ness segment should allow additional time for their trips Monday. Officials said riders might want to consider alternative routes if they're on tight schedules.
