Two Maryland Teens Killed From Train Derailment!

Oh this is just so tragic!

19-year-old college students Rose Mayr and Elizabeth Nass were killed Tuesday, when a train carrying mass amounts of coal derailed around midnight (train pictured above).

The two teens were sitting on the edge of a railway bridge above Ellicot City, Maryland, with their backs to the tracks, and were apparently tweeting moments before the freak accident occurred.

One tweeted picture shows a girl's feet dangling above the road below, with the caption "Levitating," and another tweet states:

"Drinking on top of the Ellicott City sign with @ r0se_petals."

Apparently, when the train cars derailed, Rose and Elizabeth -- who were both set to start their junior year of college this fall -- were fatally submerged in coal.

There is no word yet as to WHY the train derailed, but an investigation conducted by the National Transportation Safety Board is currently underway.

Please please please people, stay away from train tracks, it is NEVER safe to get close to fast-moving, giant, heavy machinery.

So so unbelievably sad! Our hearts go out to Rose and Elizabeth's families and loved ones.
