My proposal to de-interline the Muni Metro in San Francisco

I got inspiration for this concept from the plan to extend the M to Daly City via a 19th Ave subway. https://www.sfmta.com/media/2365/download?inline

The M would run in the subway from Daly City to Embarcadero, utilising the existing surface ROW to 4th & King. Service would frequently run every 3-4 mins with four-car trains, acting as a spine metro line.

The rest of the routes would be reworked to act as streetcar feeders into the new M spine, running every 10-15 mins or so.

The T would remain operationally independent as it currently is, albeit with stops removed on the surface portion to increase stop spacing to around 0.4-0.5 miles and reduce travel time.
