Express routes

SamTrans discontinued its last remaining express route, KX, by merging it into route 398 on August 5, 2018. Since then, the SamTrans board adopted the Express Bus Feasibility Study on December 5, 2018.^[3][4] The agency recommended launching six new express routes, starting with two pilot routes scheduled to begin in summer 2019. One route began service on schedule, but the other began service five years late. The first route, FCX, travels between San Francisco and Foster City along US 101. Route EPX provides service between San Bruno and East Palo Alto.

An early-morning weekday express route with limited trips, separate from the pilot program, was introduced on February 11, 2019. Route 713 provided replacement service for BART between 4:00 am and 5:00 am while seismic retrofit work was performed in the Transbay Tube. It currently runs between the Salesforce Transit Center and Millbrae Intermodal station via SFO Intl. Airport. This route was made a permanent addition.^[5]

The first new express route, designated FCX, started service on August 19, 2019. FCX operates two trips in each direction with headways of approximately 30 minutes during peak weekday commute hours, using recent buses that feature onboard Wi-Fi.^[6][7]

The next two express routes began in 2024, one serving between San Francisco/San Bruno and East Palo Alto (EPX). The other, PCX, serves Pacifica while serving stops at bus pads along the CA-1 freeway.
