Executive Summary

​On August 20, 2012, about 11:54 p.m. eastern daylight time, an eastbound CSX Transportation (CSXT) coal train, U81318, derailed the first 21 cars at milepost (MP) 12.9 while crossing the railroad bridge over Main Street on the Old Main Line (OML) Subdivision in Ellicott City, Maryland. The train consisted of two locomotives and 80 loaded coal cars; the train length was 4,227 feet and the weight was 9,873 trailing tons. Seven of the derailed cars fell into a public parking area that was below and north of the tracks. The remainder of the derailed cars overturned and spilled coal along the north side of the tracks.

They climbed over a short wooden fence and entered CSXT property without authorization to access the railroad bridge. They were sitting on the bridge during the derailment. Both individuals were killed by the spilled coal.
