Windsor station

The Windsor station opened for passenger service on Saturday, May 31.  The Windsor pathway segment opened on June 13, 2025.

 

Temporary suspension of early morning Windsor service

At the request of the Windsor Town Council, SMART has temporarily suspended three early morning weekday southbound trips departing from Windsor until the Quiet Zone in Windsor is established.   

Effective Monday, June 23, southbound trips that are being temporarily suspended are: 

  • Trip 1 - departing at 4:35 AM 
  • Trip 3 - departing at 4:58 AM 
  • Trip 5 - departing at 5:30 AM 

These trips will depart from Sonoma County Airport Station at their regularly scheduled times. 

The Town of Windsor is in the process of applying to the Federal Railroad Administration (FRA) to establish a Quiet Zone. Once approved and implemented, routine train horn use at designated crossings will be eliminated, except in emergency or safety-critical situations.

Until a Quiet Zone is established, the Federal Railroad Administration requires SMART's engineers to use the train horn when approaching grade crossings. As a result, train horns will be heard from Shiloh Road to the Windsor station.  The Town of Windsor is currently targeting late-July for the implementation of the Quiet Zone.

We understand that this may cause temporary noise disruptions and appreciate the community’s patience as we work to ensure a safe and successful start of service.

Track scrubbing

Track scrubbing, a maintenance process that cleans the railroad tracks, takes place weekly as part of routine maintenance along the entire rail line. Additional cleaning may occur as needed based on track conditions and environmental factors affecting the railway. During this process, you may notice vehicle lights and hear grinding sounds.

Petaluma North station

The Petaluma North station opened on Friday, January 10, 2025.

The pathway is still under construction, and is not yet open for use.  Technical issues with traffic signal equipment at some pathway street crossings have delayed the opening of the newest pathway segments. We are working closely with our partners including the contractor, equipment manufacturer, and County of Sonoma to resolve the issue and look forward to opening the pathway segments as soon as they are ready to be safely enjoyed.

The community walk/ride that was planned for Sunday, April 27 to celebrate the opening has been postoned.  We truly appreciate your enthusiasm, support, and patience, and we’ll announce a new date for the celebration just as soon as the pathways are ready to safely welcome everyone.  Click here for more details.
