scheduled service to San Francisco International Airport (SFO) and Transbay Terminal in downtown San Francisco. Unlike most large transit operators in the Bay Area, SamTrans outsources to private contractors the operation of a number of its routes. The current contract operator for Peninsula mainline, Coastside and paratransit services is MV Transportation. SamTrans previously operated special service for a couple of Bay Area events such as San Francisco 49ers home football games and the quirky Bay to Breakers footrace in San Francisco. Route designations Notes SamTrans reorganized its bus routes in August 1999 and adopted a new route designation system to identify service types, geographical coverage, and connections to rail services. Routes Local routes have either two or three digits or a special designation (e.g., ECR). For three-digit routes, the first digit identifies a rail connection: 1 – Connection to BART stations only (primarily routes in Daly City, Colma, South San Francisco and San Bruno) 2 – Connection to Caltrain stations only (primarily routes south of Millbrae) 3 – Connection to both BART and Caltrain stations (three routes have this designation: ECR, previously designated 390, provides service between Palo Alto and Daly City, 397 provides overnight service between San Francisco and Palo Alto as a part of the All Nighter network, and 399 provides overnight service between Daly City and San Francisco International Airport as a part of the All Nighter network.) All two-digit routes are community service routes. Most of these routes do not connect with rail and operate on school days. Express routes Express bus routes were designated by a letter and X. In December 2009, six express routes (DX, FX, MX, NX, PX, and RX) were eliminated due to budget constraints; a seventh, route CX, was redesignated Route 118. In August 2018, the last remaining express route, KX, was folded into Route 398. In April 2017, SamTrans identified fifteen potential express bus routes connecting the Peninsula counties of San Francisco, San Mateo, and Santa Clara. Most of the potential routes ran along U.S. 101, and some were planned to take advantage of managed lanes to provide speedier service. By June 2018, the list of potential bus routes was reduced to six. The draft final report was released in November 2018, and the Board adopted it in December. SamTrans anticipates relaunching express bus service in August 2019 from Foster City to downtown San Francisco along U.S. 101, followed by
