Starting April 12, Marin and Sonoma counties will see a major reshuffling of transit service under the Marin–Sonoma Coordinated Transit Service Plan (MASCOTS). This plan aims to cut wait times, improve transfers along U.S. 101, and attract more riders.
The Metropolitan Transportation Commission worked with nine transit and funding agencies to adjust schedules, consolidate routes, and target frequency boosts. They based their decisions on maps, ridership forecasts, and fare comparisons.

SMART rail service will expand by about 19 percent. Riders can expect earlier northbound departures, later evening trains, and more midday trips, totaling roughly 48 weekday trips.
These changes should make it easier to get one-seat or timed-transfer rides to San Rafael and Larkspur.
Overview of the MASCOTS plan for Marin and Sonoma counties
From San Rafael’s downtown to Sausalito and Tiburon, over to Novato and Larkspur, the plan means faster, more reliable rides during peak and midday hours. Folks in Mill Valley, Corte Madera, San Anselmo, and Fairfax will find smoother connections between local buses and SMART rail.
Getting between Marin and Sonoma County destinations should involve less waiting around. Golden Gate Transit and its partners say fares will stay steady while they rework connections for a stronger network.
The region wants to better align service on the 101 corridor with SMART, aiming for Caltrain-like transfers and more frequent service where people need it most.
Expanded SMART rail and Golden Gate Transit service
The plan really focuses on expanding SMART rail and tightening bus-plus-rail connections. Here’s what’s changing:
- SMART rail expansion: About a 19 percent increase in service, with earlier northbound departures, later evening trains, and more midday trips—roughly 48 weekday trips total. This should help with one-seat or timed-transfer options to San Rafael and Larkspur.
- Golden Gate Transit focus on Route 101: The San Rafael–San Francisco corridor will get about double the frequency, with buses every 30 minutes all day and every 15 minutes during weekday peaks.
- End of some northern Marin bus runs: Routes north of Novato on Route 101 to Santa Rosa and other stops will end. Extra SMART rail trips will pick up much of that slack.
- New Route 120: This route replaces Routes 130 and 150 in southern Marin, with timetable tweaks to improve SMART connections.
- Late-night bridge by Sonoma County Transit: There’s a single night round-trip on Route 51 between Santa Rosa and Novato from April 12 through June 30, timed to connect with Route 101.
- Fares unchanged with potential savings: Riders might see lower Clipper fares because of the new connections, though overall pricing stays the same.
Impact on local communities and rider experience
In Marin communities like San Rafael, Sausalito, Mill Valley, and Tiburon, riders will notice more frequent service and shorter waits. Some people worry about losing one-seat rides and having fewer late-night options, especially for Santa Rosans who depend on evening routes.
The agencies are trying to balance faster, more reliable daytime service with the reality that evening and night travel will look a little different across the region.
What riders should know on the ground
- Check updated maps and timetables before traveling. Some northern Marin routes will end beyond Novato, which could affect riders in places like Fairfax and San Anselmo who used to rely on longer single-seat trips.
- Temporary services and surveys are happening as agencies watch ridership and tweak the network if needed.
- Riders in Sonoma County, including those in Santa Rosa and Novato, should pay attention to late-night changes and see how the Route 51 connection might help after 9 p.m.
Fares, connections, and rider feedback
Agency officials say fares will not change under MASCOTS. Many Marin commuters could even see lower Clipper fares if transfers get smoother and timing improves.
The plan’s drawn mixed reactions. Some applaud the idea of faster, more frequent daytime service, but others worry about lost late-night options and fewer one-seat rides, especially folks in Santa Rosa.
Partner agencies are surveying riders. They’re also offering temporary services and keeping an eye on ridership so they can tweak the network if needed.
Marin travelers should check official maps and timetables for updates. Spring’s shifting into summer, and traffic patterns from San Rafael to Larkspur might change before you know it.
