Muni Metro Rail routes closed for repairs to restart in May

The San Francisco Municipal Transportation Agency (SFMTA) plans to restart more Muni Metro rail service by May, agency officials said.

The agency will extend the T Third Metro rail route between Sunnydale and West Portal, and bring the full N Judah Metro rail route back into service between 4th and King (CalTrain) and La Playa (Ocean Beach), SFMTA officials said in a blog.

Since August 2020, Muni has been making intensive subway repairs after discovering some potentially faulty overhead splices and issues with ballast in the Eureka Curve/Twin Peaks Tunnel. 

The completion of essential repairs and upgrades will allow SFMTA to reopen subway service. Crews have removed all of the splices that had been potentially defective and replaced them with splices from a new manufacturer, agency officials said.

The ballast in the Eureka Curve has also been completed and testing and certification of the subway has begun. In the meantime, SAFTA is working to make as many improvements as possible while the subway is temporarily closed.
