By moving the M-Ocean View subway line underground, Muni hopes to avoid delays and decrease travel times.

Nearly 45 years ago, Muni trains boldly went where no San Francisco train had gone before: underground.

Trains west of those hills unearth at West Portal Station, mixing with cars, pedestrians and more. Planners say that slows the subway systemwide.

“I think we built half a rapid transit system,” Liz Brisson, told the San Francisco Examiner, “now we need to build the other half.”…

The train would remain underground through the rest of its route to Parkmerced.

The previous plan ran the train underground mainly underneath 19th Avenue, but not at West Portal or at the line’s end by Parkmerced.

“This is a dramatic increase in the scope of the project,” Brisson said.

It’s also a dramatic increase in cost. The project is estimated to run $2.5 billion to $3 billion. The last time San Francisco ventured to build a new train tunnel of this magnitude was the Central Subway, the hotly contested linkage between Union Square and Chinatown…
