ELLICOTT CITY, Md. (CBSDC) - Two weeks after a deadly train crash claimed the lives of two teenage girls in Ellicott City transportation officials have released more details about the damages of the collision.

At approximately 11:56 p.m. on Aug. 20, 21 cars of an 80-car CSX coal train derailed in Ellicott City emptying coal onto the tracks and crushing everything in its collision course. Some train cars rolled off the tracks hurdling onto parked cars on the street below. Verizon service was disrupted when the derailed train damaged land line equipment.

The National Transportation Safety Board says in a preliminary one-page report that the derailment caused $2.2 million in damages.

However, the report does not name the cause of the accident which likely won’t be determined until after the full investigation is complete in 12 to 18 months.

Two 19-year-old college were killed - Elizabeth Conway Nass, 19, a student at James Madison University and Rose Louese Mayr, 19, a nursing student at the University of Delaware – when they were buried in coal from one of the tumbling cars. The girls were hanging out on the bridge the train was scheduled to travel over just before it derailed.

The Safety Board did say the train was traveling at the maximum authorized speed of 25 mph when it derailed.

A temporary fence has been constructed to prevent people from getting near the bridge.
