Projects Update

SMART Larkspur Extension Project Overview

SMART began construction of its rail extension to Larkspur in July 2017. The extension to Larkspur includes 2.2 miles of track connecting San Rafael and Larkspur, a terminal station in Larkspur Landing, three bridges, and utilizes the recently rehabilitated Cal Park Tunnel that currently provides a bicycle/pedestrian connection to Larkspur from San Rafael.

Following construction of the Larkspur Extension, safety signals and systems will be thoroughly tested prior to the start-up of service to Larkspur Landing. SMART train service to Larkspur is projected to begin in late 2019.

Overnight Systems testing for Larkspur Extention

Upcoming overnight testing dates:

There are currently no operations scheduled. We will provide updates when they are available.

As a part of the testing process, you may see crossing gates and bells activated without a train an hour before the beginning and end of each systems testing session. 

We understand that the use of the train horn may be disruptive, and we appreciate your patience as we work hard to complete this testing phase as efficiently as possible. Please note, there may be additional testing nights depending on test results. Thank you for your understanding as we strive to ensure the long-term safety of our community. For more information, please call (707) 794-3077 or email

Overnight Operations in Santa Rosa

Sonoma-Marin Area Rail Transit (SMART) will be conducting railroad crossing tests for freight trains on Sunday, October 27, from 12:00 a.m. to 9:00 a.m., at the Guerneville Road railroad crossing in Santa Rosa. The Federal Railroad Administration (FRA) requires SMART to sound its train horn when testing railroad crossings, so residents may hear the train horn during these hours.

We thank you for your understanding, as SMART strives to ensure the long-term safety of our neighbors and community.

Overnight Work in Penngrove

SMART will be performing work, on behalf of the County of Sonoma, to make improvements to the railroad crossing in Penngrove. This includes new quad-gates, and improvements to the adjacent sidewalk. Construction work will take place from September 30 through October 31. Some overnight work will be required September 30 through October 3. 

Town of Windsor Extension Project

The SMART Board of Directors recently launched the next phase of construction work to extend commuter service to the Town of Windsor, by authorizing the expenditiure of $24 million to begin rail safety upgrades and design work needed to expand the rail line north by 3 miles from the current northbound terminal near the Sonoma County Airport. Construction work is estimated to begin in 2020 and systems testing is expected to begin in 2021.


SMART Receives Four New Rail Cars

SMART's new rail cars are currently undergoing safety testing. SMART’s vehicle testing is part of the safety requirements needed before placing the new cars into service.


SMART Pathway Construction Project

SMART was selected to receive a $12.6 million grant to fund its bicycle and pedestrian pathway project in Petaluma, Rohnert Park and Santa Rosa. SMART is currently gearing up to begin construction of the bicycle-pedestrian pathway between Payran Street to Southpoint Boulevard in Petaluma. To view a progress map of the pathway, please click here.

SMART has completed the following segments:

  • Healdsburg: Front Street to Grant Street,
  • Santa Rosa: Sixth Street to Guerneville Road,
  • Rohnert Park/Cotati: East Avenue to Golf Course Drive.
  • Rohnert Park: Sonoma Mountain Village to the Cotati SMART Train Station,
  • Southwest Santa Rosa: Hearn Avenue to Bellevue Avenue, with pathway connections to Downtown Santa Rosa SMART Station.
  • Novato/Petaluma: SMART Novato San Marin Station to County Line,
  • Novato: Rush Creek Place to SMART Novato San Marin Station,
  • Novato: SMART Novato Hamilton Station to Hamilton Parkway,
  • Novato: Franklin pedestrian crossing (near Sutter Health) to Grant Street in downtown Novato (future Novato Downtown Station),
  • San Rafael: North San Pedro Road to SMART Marin Civic Center Station,
  • San Rafael: Merrydale Road to Mission Avenue.


Passenger Rail Feasibility Study: Novato to Suisun

At the request of the California State Transportation Agency, SMART has reviewed the technical feasibility of implementing passenger rail service between Novato and Suisun City to a connection to the Capitol Corridor passenger rail system.  The Feasibility Study inventories the facilities and natural environment, develops conceptual options for rail service, provides high-level cost estimates and approximates travel times. This exciting prospect could provide a transportation alternative to those that travel the Highway 37 corridor and build upon transit connections that exist today.
