Two 19-year-old college students who were happily tweeting photos of themselves atop a railroad bridge in Maryland were killed when a coal train derailed at the site last night, reports NBC Washington. The best guess is that the teens were sitting on the edge of the bridge in Ellicott City with their backs to the passing train when it derailed for reasons that are still unclear. Elizabeth Nass was a student at James Madison University and Rose Mayr went to the University of Delaware.
At some point before the derailment, Mayr tweeted a photo showing a view of the city from the bridge and another showing their feet dangling from it. Investigators didn't know the teens were on the bridge until friends and relatives came forward after the derailment. Click to read more. (Read more train stories.)
