a second route in Spring/Summer of 2020 from Palo Alto to western San Francisco along I-280. The Foster City–San Francisco route was launched as FCX in August 2019, but ridership and frequency have been adversely impacted by the COVID-19 pandemic in the San Francisco Bay Area. The launch of the other proposed express route planned for Phase 1, PAX (Palo Alto to western San Francisco), has been delayed indefinitely. Phase 2 of the express bus plan includes two additional routes: EPX (East Palo Alto to San Bruno) and an un-named route (San Mateo to downtown San Francisco); EPX is anticipated to launch in 2023 after SamTrans completes acquisition of XE40 battery-electric buses. Fares Since January 1, 2020 Notes SamTrans offers bus tokens for adult and youth local fares ($16 and $10, respectively) in packages of ten. Multiple tokens or combinations of tokens and cash are accepted for journeys requiring higher fares. Tokens are promoted as being easier to handle than cash, and also include discounts. For example, a package of tokens includes two free rides assuming the others are worth $2 each (adult) or $1.25 each (youth). SamTrans does not provide transfers but offers a Day Pass which allows unlimited rides on local routes and a credit on higher-cost routes. The cost of the Day Pass is thrice the one-way fare on the local routes for adults, youth, and seniors/disabled/Medicare cardholders. As of December 22, 2010, Clipper card fare machines became fully operational throughout the system, allowing riders to pay fares using Clipper card, a transit smart card that is also accepted by most other Bay Area transit agencies. Clipper cards come in four varieties: adult, youth, senior and disabled (which includes Medicare cardholders). Adult Clipper cards may be obtained from a wide variety of vendors, but youth, senior and disabled Clipper cards must be obtained from SamTrans or another Bay Area transit agency. Each Clipper card contains some sort of stored value (e.g., monthly passes, "Clipper Cash" e-funds used for transit fares) and the history of recent trips using the card. Clipper cards generally confer an approximately 10% discount relative to cash fares. With the exception of youth summer passes, all SamTrans monthly passes must be loaded onto a Clipper card. Youth, senior and disabled monthly passes may only be loaded onto a corresponding Clipper card obtained from SamTrans or another Bay Area transit agency. To ride SamTrans with
