Windsor Station
SMART is preparing to launch passenger rail service to Windsor in late Spring 2025. As part of this process, the Sonoma County Airport station will be temporarily closed on weekends in April for systems testing. All other SMART stations will remain open. The testing is scheduled for the following dates:
- Saturday and Sunday, April 5–6
- Saturday and Sunday, April 12–13
- Sunday, April 20
- Saturday and Sunday, April 26–27 (tentatively)
Train operations during testing
Test trains will operate between the SMART Airport train station and Windsor from 7:00 AM to 10:00 PM beginning in early April. During testing, trains will sound their horns and bells intermittently, as required by federal safety regulations.
Use of train horns and Quiet Zone
The Town of Windsor is in the process of applying to the California Public Utilities Commission (CPUC) 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.
During systems testing and until a Quiet Zone is established, the Federal Railroad Administration requires the use of horns and bells for safety purposes. As a result, train horns and crossing bells will be heard from Airport Boulevard to Windsor.
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.
