Dallas police officers responded to a major accident call in the 4900 block of Military Parkway, a corridor that runs through the Pleasant Grove area near several rail crossings. A preliminary investigation determined that a man had been hit by a train, according to the department.

Dallas Fire-Rescue crews transported the man to a hospital. At the time he was taken from the scene, his condition was described as critical, the department said. Authorities did not immediately provide an update on his status later in the day.

Police said no arrests have been made in connection with the incident, and detectives are continuing to investigate the circumstances that led to the collision. The department did not release the man's name or age, and it was not immediately clear whether he was on foot near the tracks or attempting to cross at the time.

Rail safety has been a recurring concern in Dallas neighborhoods where freight and passenger lines cut through residential and commercial corridors. Military Parkway is a busy east-west route that intersects with rail infrastructure in a part of the city where pedestrians often walk along or near the tracks.

Anyone with information about the incident is asked to contact Dallas police. The department has not said whether foul play is suspected, and no further details were available Sunday.
