Windsor station

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

 

Windsor Quiet Zone and Service

At the request of the Windsor Town Council, SMART temporarily suspended three early morning weekday southbound trips departing from Windsor pending the establishment of a Quiet Zone in Windsor.   

On Monday, August 4, 2025, the Federal Railroad Administration (FRA) approved the Town of Windsor's Quiet Zone. 

Effective Tuesday August 5, 2025, the southbound trips that were temporarily suspended will resume: 

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

With the Windsor Quiet Zone now approved, routine use of the train horn at designated crossings in Windsor will be discontinued starting Tuesday, August 5, 2025. 

SMART engineers will continue to sound the train horn in emergency or safety-critical situations—such as when people, vehicles, or construction crews are on or near the tracks—or when required by SMART’s operating rules.

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.
