HAWKINS COUNTY, Tenn. (WJHL) – A loud, explosion-like noise heard around the Tri-Cities Saturday night was no cause for alarm, rail officials say.

According to CSX Public Safety, the train had to make an emergency stop after it lost air pressure for its primary braking system.

The official stated that trains are designed with two braking systems, a primary air braking system, and an emergency braking system.

Once the emergency stop was initiated, the wheels locked up and the train cars came together causing a loud noise that was heard throughout the area.

Rail officials state that there were no crew injuries related to the incident.

Residents throughout the region reported hearing the sound, and some said they felt the ground shake under their feet.

CSX officials say the train has since restarted operations shortly after the stop after air pressure was reestablished.
