## 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. 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.
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.
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.

| KX | Main Street and Folsom Street Transbay Terminal | Redwood City Caltrain Station | San Francisco, San Francisco International Airport, Belmont, San Carlos, Redwood City | Operated as an express service route (via Highway 101 and 9th/10th Streets) between San Francisco International Airport and downtown San Francisco. Passengers with luggage were prohibited from traveling on the express portion of the route until 2013 due to a lawsuit filed in the 1970s by a private shuttle service called San Francisco Airporter, which contended that SamTrans' public subsidy gave it an unfair competitive advantage. Although San Francisco Airporter was sold in 2001 and ceased airport service in 2006, the luggage ban continued until June 1, 2013, when SamTrans was cleared to do so by the Federal Transit Administration. San Francisco Terminal service was located at the southwest corner of Main Street and Folsom Street, just outside the Temporary Transbay Terminal. Pick-ups were on Main Street; drop-offs were on Folsom Street. Served Palo Alto station and Stanford Shopping Center until August 11, 2013.
