Windsor station

 

During April, Systems Testing will be conducted

Throughout April, test trains will operate 7 days a week between the Sonoma County Airport station and the Windsor station from 7:00 AM to 10:00 PM. During testing, trains will sound their horns intermittently, as required by federal safety regulations. Grade crossing warning systems, such as lights, gates, and bells will be operated during the Systems Testing period.

Systems Testing is done to evaluate the safe operation of warning devices, train control system, and proper speed enforcement throughout the railway extension to Windsor.

During the Systems Testing period, the Sonoma County Airport station will be temporarily closed on weekends in April. All other SMART stations will remain open.

 

During May, Simulated Service will be conducted

Beginning in early May, SMART will operate trains to simulate the frequency of the passenger service train schedule. During this period trains will operate without passengers.

Simulated Service is done to familiarize train engineers with the new territory and to test the train control systems under full-frequency operation.

During Simulated Service trains will operate at a frequency of 44 trips per day. The hours of simulated service are 4:00 AM and 10:30 PM on weekdays, and 6:30 AM and 9:30 PM on weekends

Until the Town of Windsor establishes a Quiet Zone, train horns will be sounded at Shiloh Road, Mitchell Lane, the Windsor roundabout, and the Windsor station access crossing.

 

Use of train horns and Quiet Zone

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.

During systems testing and 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 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.
