JACKSONVILLE, Fla. – A bicyclist crossing tracks on the Westside was struck and critically injured Monday morning by an Amtrak train.

According to the Jacksonville Sheriff's Office, a northbound freight train had just cleared the tracks on McQuade Street about 8 a.m. and a man on a bicycle wearing ear buds proceeded across the track while the crossing arm was still down. He was struck by the southbound Amtrak train.

The bicyclist was taken to UF Health Jacksonville with life-threatening injuries, according to Lt. Kelvin Anderson. His name was not released at the scene. Police are investigating, including checking surveillance video recorded on the engine of the train.

After just over an hour, the train was allowed to proceed on its route.
