Sonoma-Marin Area Rail Transit

What Sonoma-Marin Area Rail Transit does

Sonoma-Marin Area Rail Transit (SMART) is a California special district that operates a 70-mile passenger rail and freight corridor along with a parallel Class I multi-use pathway across Marin and Sonoma counties in the North Bay region. The agency's core product is commuter rail service connecting Larkspur in Marin County to Santa Rosa and Windsor in Sonoma County, with active construction underway to extend service northward to Healdsburg and ultimately Cloverdale. SMART operates a fleet of diesel multiple unit (DMU) trains on its 15-station system, supplemented by SMART Connect on-demand microtransit shuttles for first/last-mile connectivity, and runs freight rail operations over the same right-of-way in partnership with Northwestern Pacific Railroad. Safety and operations technology includes Federal Railroad Administration-certified Positive Train Control and an FTA-certified Automatic Passenger Counter system installed across the train fleet.

The agency's commercial model is a hybrid public-farebox structure typical of U.S. commuter rail. Operating revenue is generated through passenger fares (Clipper card, SMART mobile app, single rides, 31-Day Passes, 50% low-income discount, free youth/senior pilot), overnight parking fees at station lots via ParkMobile ($5/night), station platform and onboard advertising managed by Lamar Transit, and freight rail fees. Capital expenditure is overwhelmingly grant-funded: SMART has secured $269 million for the Healdsburg Extension, plus additional tranches from the Federal Transit Administration, the State of California, the Metropolitan Transportation Commission, and California Climate Investments, with dedicated half-cent Measure Q sales tax revenue underwriting operations. The agency coordinates regionally through the Marin-Sonoma Coordinated Transit Service (MASCOTS) Plan with nine transit agencies, interoperates with Golden Gate Ferry at Larkspur for San Francisco access, and integrates with Clipper BayPass programs serving students at Santa Rosa Junior College.

SMART is governed by an elected Board of Directors and managed by General Manager Eddy Cumins (appointed October 2021), with Heather McKillop serving as Chief Financial Officer (appointed November 2020). The agency holds an exclusive regulatory franchise along its corridor, has received the California Transportation Foundation's Transit/Rail Project of the Year award in 2018 and again in 2026, and has been designated by the FRA Corridor Identification and Development Program for future federal passenger rail funding support.
