Return to top speeds in Twin Peaks Tunnel delayed 

Muni passengers hoping for a return to faster-moving trains inside the Twin Peaks Tunnel will have to wait a little bit longer.

For decades, Muni trains have zipped through the Twin Peaks Tunnel, which connects the West Portal and Castro stations, at 50 miles per hour, but since 2006, ongoing rehabilitation work inside the underpass has slowed down speeds to 35 mph.

Backed by the urging of Cameron Beach, a board member of the Municipal Transportation Agency, which operates Muni, agency engineers said they could get service back up to 50 mph by May 1 .
However, with the new arrival of John Haley, who now manages Muni’s transit operations, the speeds inside the Twin Peaks Tunnel are getting another look.

At the MTA’s Policy and Governance Committee meeting on Tuesday, the agency’s executive director Nat Ford said that Haley was feeling some “uneasiness” about returning speeds inside the tunnel to 50 mph, and that he would need more time to review the situation. In the past, the agency said the 50 mph speeds would create bottlenecks at the tunnel’s terminuses.

Ford did not have an exact date for when — or if — the 50 mph speeds would return.
