Today, San Francisco only has trains along Market Street, fingering out into a half dozen neighborhoods. Most of the city is served by buses. Originally, many of those buses were, in fact, trains: > ...as SF's rail network was removed or replaced with bus lines in the mid-century, it went from 16 rail lines to five... The reason we still have the trains we do is because they were the lines that used tunnels, so they couldn't easily be replaced by buses. The World's Fair, which also brought us the Palace of Fine Arts, spurred the construction of many of those train routes. You used to be able to get to the Presidio by train! Imagine if, instead of spending effort digging up the tracks to replace them with buses, they buried the tracks and built an actual metro system: you could get around the city without a vehicle. https://www.sfmta.com/blog/how-munis-streetcar-lines-got-their-letters https://www.sfmta.com/blog/how-munis-streetcar-lines-got-the...
