Two Pittsburg, Kan., teens were killed Sunday when the van they were riding in was struck by a train, according to the Oklahoma Highway Patrol.

According to the OHP., the two boys were among a van of family members traveling in rural Craig County near Welch, when their van collided with the train.

Sunday's tragedy comes during the same week much of the nation's state authorities are sponsoring Operation Lifesaver, a public education program established in 1972 to end collisions, deaths and injuries at places where roadways cross train tracks and on railroad rights-of-way.

According to a nationwide study conducted by the organization, every 120 minutes a vehicle or pedestrian is struck by a train in the United States.

Last year in Oklahoma, 70 train collisions resulted in 16 fatalities. Since the beginning of this year, six train-related fatalities have been reported in the state.
