Route FCX | Route 250 | Routes 251/256 | Route 260

Route 294 | Route 295 | Route 292 | Route 397 | Route 398 | Route 249

Route FCX | Foster City - San Francisco Express Service

Existing Service

Route FCX is a commuter route providing a direct connection between Foster City and San Francisco on weekdays. The service runs on the highway with limited stops. Route FCX operates in both directions in mornings and evenings.

Recommended Changes

FCX Alternative

Coverage (Where it goes)

Route FCX will continue to run the same routing as it currently does. However, due to low ridership, Route FCX will only operate into San Francisco in the morning and out of San Francisco in the afternoon.

Frequency (How often it runs)

Route FCX will operate five trips in the morning and six trips in the evening, matching service provided before the COVID-19 pandemic.

Hours of Service (When it runs)

Hours of service would not change.

Route 250 | 5th/El Camino Real (San Mateo) – College of San Mateo

Existing Service

Route 250 has above average ridership. It serves several major destinations, including downtown San Mateo, Hillsdale Shopping Center, and College of San Mateo (CSM). Public input indicated issues with reliability on South Norfolk Street and crowding on certain trips.

Recommended Changes

Route 250 Alternatives

Coverage (Where it goes)

In the new network, Route 250 would end slightly east of El Camino Real in downtown San Mateo due to low ridership beyond that point.

To better serve the new Hillsdale Caltrain station, Route 250 would travel on Saratoga Drive, then onto Franklin Parkway and 31st Avenue. The stops on Hillsdale Boulevard between Saratoga Drive and El Camino Real would no longer be served by Route 250.

Between Hillsdale Shopping Center and CSM, Route 250 would use W Hillsdale Boulevard, instead of CA-92. This change would provide a faster trip for riders to CSM. Route 294 will continue to cover the segments of Alameda de las Pulgas served by Route 250 today.

Trips on Route 250 that operate only on school days serving Bayside Middle School would continue to operate and be renamed as Route 50.

Frequency (How often it runs)

In the new network, Route 250 operates more often, every 15 minutes, on weekdays during the peak periods. Route 250 would also run more frequently on weekends, with an increase to every 30 minutes.

Hours of Service (When it runs)

No changes to hours of service are proposed.

Route 251/256 | Foster City – Hillsdale Mall/Hillsdale Mall - Foster City

Existing Service

Routes 251 and 256 are two loop routes serving Foster City. Both routes have low ridership with many trips carrying no passengers. School trips on these two routes have high ridership. Routes 251 and 256 also overlap with shuttle routes in Foster City. Both routes suffer from reliability issues stemming from the congestion on Hillsdale Boulevard. Public input included requests for Sunday service, better reliability and clearer route design.

Recommended Changes

Route 251/256 Alternatives

Coverage (Where it goes)

In the new network, Routes 251 and 256 are consolidated into one simple route that serves the highest ridership stops and densest areas in Foster City. A new Route 251 would serve Foster City Boulevard, Beach Park Boulevard, and Edgewater Boulevard. The bus would use Fashion Island Boulevard to avoid traffic on Hillsdale Boulevard in and out of Foster City. Residents on portions of Hillsdale Boulevard, Beach Park Boulevard, and Shell Boulevard would need to walk further to access the bus than they do today.

Trips on Route 251 and 256 that operate only on school days serving Hillsdale High School would continue and be renamed as Route 51.

Frequency (How often it runs)

Service would operate every 60 minutes, seven days a week.

Hours of Service (When it runs)

The new Route 251 would receive new Sunday service. Route 251 would operate from 6:30 a.m. to 8:30 p.m. during the weekdays and 7:30 a.m. to 7:00 p.m. on weekends.

Up to Top ^

Route 260 | San Carlos Caltrain – College of San Mateo

Existing Service

Route 260 has below average ridership. High school and middle school students with destinations on Ralston Avenue are the primary market and most trips outside of school bell times carry very few passengers. Ridership to the College of San Mateo (CSM) is also low. Part of this route is covered by the free Twin Dolphin Shuttle. Public input included requests for later evening service.

Recommended Changes

Route 260 Alternative

Coverage (Where it goes)

Route 260 would be shortened to run between Ralston Avenue at Cipriani Boulevard and San Carlos Caltrain via Bridge Parkway in Redwood Shores. The shortened route would better connect Caltrain riders with jobs in Redwood Shores and would remove fixed route service in Redwood Shores east of Bridge Parkway. Some riders on Marine Parkway would need to walk up to 10 minutes to the nearest stop for service.

School service on Routes 60 and 67 would continue to be available at all current stops in Redwood Shores.

Frequency (How often it runs)

Route 260 would operate every 30 minutes on weekdays during the peak periods and every 60 minutes during the midday, evenings, and all day on the weekends.

Hours of Service (When it runs)

Hours of service would not change. The new Route 260 would receive new Sunday service.

Route 294 | San Mateo Medical Center – Main/Poplar (Half Moon Bay)

Existing Service

Route 294 connects Half Moon Bay to San Mateo, but has below average ridership. Public input included requests for more frequent and later service to Half Moon Bay.

Recommended Changes

Route 292 Alternatives

Coverage (Where it goes)

Route 294 would continue to serve all stops in Half Moon Bay and in the Hillsdale area of San Mateo, including better connections to the new Hillsdale Caltrain station.

Due to low ridership, deviations to College of San Mateo (CSM) and San Mateo Medical Center would be discontinued. Riders could continue to access CSM with a transfer to Route 250 in San Mateo. San Mateo Medical Center would be accessible with a transfer to Route 295 or about a five-minute walk.

A new service called “on-demand” would be provided in the Half Moon Bay area. This service allows people to call or use a mobile app to schedule a ride from where they are to where they want to go within a certain zone. This service would connect riders directly to places on the mid-Coast and to bus routes 294 and 17 to reach more destinations.

Frequency (How often it runs)

In the new network, Route 294 would run more often during the midday on weekdays. The route would operate every 60 minutes, seven days a week.

Hours of Service (When it runs)

Hours of service would not change.

Route 295 | San Mateo Caltrain – Redwood City Caltrain

Existing Service

Route 295 is a low ridership route connecting Redwood City, San Carlos, and San Mateo primarily via Alameda de las Pulgas. With the exception of school times, most trips carry few passengers. Public input suggested that reliability is an issue.

Recommended Changes

Route 292 Alternatives

Coverage (Where it goes)

In the new network, Route 295 would run between Redwood City, San Carlos Caltrain, and Hillsdale Shopping Center. Service north of Hillsdale Shopping Center would be discontinued and partially replaced with the new Route 249. Route 295 would no longer serve Cordilleras Center due to low ridership.

The portion of the current route between Redwood City and San Carlos would operate on Jefferson Avenue instead of Whipple Avenue. Existing riders on Whipple Avenue could walk about 10 minutes to Alameda de las Pulgas or El Camino Real for service.

In San Carlos, the route would use El Camino Real instead of Cedar Street, between San Carlos Avenue and Brittan Avenue.

Riders on Alameda de las Pulgas between W Hillsdale Boulevard and CA-92 would continue to have service through Route 294. North of CA-92, riders could utilize the new Route 249.

Frequency (How often it runs)

In the new network, Route 295 would operate every 60 min all day, seven days a week.

Hours of Service (When it runs)

Route 295 would receive new service on Saturdays and Sundays. Hours of service on weekdays would not change.

Up to Top ^

Route 292 | San Francisco – SFO - Hillsdale Mall

Existing Service

Route 292 has average ridership, but is a very long route, making reliability a challenge. During public outreach, riders asked for better reliability and faster speeds. People also requested more frequent service and that the route continue into San Francisco.

Recommended Changes

Route 292 Alternatives

Coverage (Where it goes)

Route 292 will continue to serve San Francisco in the new network. In San Francisco, Route 292 would operate as a limited-stop service with stops approximately every half mile. Stops along Potrero Avenue and Mission Street would be the same as those used by Route FCX.

A new connection on Route 292 to Millbrae Transit Center would improve access to San Francisco Airport, BART, Caltrain, and ECR bus service.

Frequency (How often it runs)

Frequency of service would not change.

Hours of Service (When it runs)

Hours of service would not change.

Route 397 | Palo Alto Transit Center - Downtown San Francisco

Existing Service

Route 397 provides a late-night connection between East Palo Alto and downtown San Francisco. It operates limited trips between 12:45 a.m. to 6:30 a.m. when Caltrain is not running. A full-length trip takes just under 2.5 hours.

Recommended Changes

No changes are recommended for Route 397.
Route 397

Route 398 | San Francisco – SFO – Redwood City Transit Center

Existing Service

Route 398 runs between Redwood City and Downtown San Francisco, providing a mix of local and express service. The route duplicates Route ECR and Caltrain service areas. It runs every 60 minutes, with one-way trips taking nearly two hours in full, much longer than trips on Caltrain.

Ridership is highest between SFO Airport and San Bruno BART. Half of all trips carry fewer than five passengers into or out of San Francisco. North of San Bruno BART, BART is a faster way to get downtown than Route 398.

Recommended Changes

Route 398 Alternatives

In the new network, Route 398 is eliminated. The resources used to operate Route 398 would allow SamTrans to improve weekend service on Route ECR and Route 130, and extend SamTrans service into Oyster Point.

Route 398 riders would have the options of using Route ECR, Caltrain, or during rush hour, the new Route EPX connecting East Palo Alto, Redwood City, and SFO to San Bruno BART. Route 292 will also continue to provide service to downtown San Francisco from San Mateo.

Route 249 | San Mateo Caltrain – College of San Mateo (NEW!)

Proposed Route Details

Route 249 Alternatives

Coverage (Where it goes)

Route 249 would be a new SamTrans route connecting the College of San Mateo (CSM) and the downtown San Mateo area via West 3rd Avenue, Parrott Drive, Alameda de las Pulgas, and CA-92.

This route would provide a faster, more direct route between downtown San Mateo, Caltrain, and College of San Mateo and better serve existing student residential patterns.

Frequency (How often it runs)

Route 249 would operate every 30 minutes on weekdays, and every 60 minutes on weekends.

Hours of Service (When it runs)

Route 249 would operate from 6 a.m. to 7 p.m. on weekdays, and 8 a.m. to 7 p.m. on weekends.
