One person is dead and two others are hospitalized after they were struck by trains in separate incidents just hours apart in metro Atlanta on Monday.

In the first case, two people were seriously injured after they were hit by a train near Dobbins Air Reserve Base early Monday morning, according to Cobb County police. Both people were on the tracks that run along Atlanta Road between South Cobb Drive and Austell Road around 3 a.m. when they were struck, officials said.

When officers got to the scene, they found one victim underneath a train car with a severe lower leg fracture and a head injury, police said. An officer applied a tourniquet to the victim’s leg until emergency medical personnel arrived.

The second victim was found near the tracks with a possible hip injury but was described as stable and alert, according to authorities.

Both were rushed to Wellstar Kennestone Hospital. An update on their condition was not provided.

“CSX appreciates the quick response of Cobb County first responders,” a spokesperson for the rail company said in a statement.

Nine hours later, just before noon, another person was struck by a CSX train. This time, the incident unfolded in Atlanta along the tracks near Howard Street and Blayton Circle right next to I-20 in the Penelope Neighbors area.

Atlanta police responded and found the person dead, officials said. No information about the victim was shared by police.

“CSX extends its deepest sympathies to those impacted by this incident,” the company spokesperson said. “This is an unfortunate reminder of the very real dangers of trespassing on railroad property.”

It is not clear why the victims were on the tracks.

Another person was hit by a train Thursday in Duluth. In that case, a 15-year-old boy was walking along the tracks near the intersection of Brock Road and Main Street when a train “clipped” him around 5:20 p.m., police said.

“We believe that he had his AirPods in his ear and didn’t hear the train coming,” Duluth police spokesperson Cpl. Ted Sadowski said.

The boy was critical but stable at the time.
