The safety of trestles is once again the topic of debate after a 21-year-old LU student died after being struck by an oncoming train on the high trestle behind Riverside Park. WLNI’s Mornings had a representative from Norfolk Southern on the show discussing the dangers. Saturday’s deadly incident is the latest of several trestle accidents in recent years. A man was struck and killed by a train on the trestle in October 2012 and a Liberty University student was also killed and another seriously injured in November 2011 in the same location. In America, a person or vehicle is hit by a train roughly every three hours. Robin Chapman, Norfolk Southern’s Director of Public Relations told WLNI listeners about a non-profits mission.
