Train Testing

Testing of grade crossing warning and traffic signal equipment at Airport Boulevard and Shiloh Road that was originally scheduled for Sunday, August 24, 2025 has been rescheduled to Sunday, September 7, 2025. 

This testing will include the operation of a test train traveling between the area north of Mitchell Lane to the SMART Airport station.

SMART engineers will use the train horn at Airport Boulevard and Shiloh Road and will use the bell as normal at all crossings.  Testing is anticipated to begin at approximately 3:30 a.m. and conclude by or before 7:30 a.m.

During this time, residents and motorists may see flashing lights and hear audible bells and train horns periodically. Construction personnel will take measures to minimize the duration of the bells as much as possible to limit impacts. Traffic control measures will be in place, allowing vehicles to pass through as directed. Please use caution and follow the directions of traffic control personnel.

 

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.
