FRANKFORT, Ind. — Railroad crossings in Frankfort from Rossville Avenue to William Street are open once more after a serious accident involving a train and a pedestrian, authorities said.

The Frankfort Police Department had to close the crossings for a couple of hours as the accident was investigated.

Police said at approximately 5:24 p.m. a pedestrian walking north, crossed the railroad track at the Rossville Avenue crossing and was struck by the westbound traveling train.

Once on scene, officers saw two witnesses pull 18-year-old Christian Lindenmayer of Frankfort from under the train and attempted to apply make-shift tourniquets. Lindenmayer was airlifted to an Indianapolis hospital. 

According to the preliminary investigation, police believe Lindenmayer was walking while wearing headphones and a hooded sweatshirt. He did not hear or see the train.

Police said that Lindenmayer was in critical but stable condition.
