In the Bay Area, Foothill Expressway literally replaced a good sized chunk of a rail line. Prior to the early 60s, one of the Penninsula Commute rail routes actually split off in Palo Alto (right where Groupon is now, and where a Y existed until 30 some years ago), went down across El Camino and through where the VA is, and down Foothill to Los Altos, ultimately connecting up with the extant Permanente Branch. That was an alternate commute route from San Jose to San Francisco, hitting the west valley and south of San Jose. Outside of the Key System, that was I think the biggest loss of rail transit in the Bay Area.
