Norfolk Southern continuing cleanup from Ravenna Township, Sandusky derailments

The route goes through East Palestine and is believed to be the same route taken by a train carrying hazardous material that derailed there, causing an environmental catastrophe on Feb. 3.
The Norfolk Southern train derailment site in November in Portage County, along with another that happened in October in Sandusky, still being cleaned up months after they occurred, as the railroad also scrambles to deal with the derailment in East Palestine.
The train was a general manifest, which means mixed freight as compare to a single commodity like grain, oil, automobiles, coal or containers/trailers (intermodal).
The 238-car train that derailed in Portage County was carrying a variety of freight, including 63 cars containing unidentified hazardous materials, according to a mandatory accident report Norfolk Southern filed with the Federal Railroad Administration. The railroad previously said 22 derailed cars were predominantly auto racks that carry vehicles and hoppers holding rock salt. About 300 tons of rock salt piled from three cars, according to the report.
In the past, 238 cars would have been two or three trains. Over the past decade, the six largest (Class 1) railroads have been increasing lengths of trains in order to reduce the number of crew required to move the freight. Two people (engineer and conductor) and sometimes 3, if there is a brakeman, operate a train in the lead locomotive. Locomotives are connected (MU'd) at the front, but some locomotives may be placed in the middle and/or rear of the train (as distributed power units, DPUs) to distribute the driving force. Use of DPUs depends on length of train and ruling grades on a route.
The Norfolk Southern report, which still has to be verified by the Federal Railroad Administration, said the primary cause of the Ravenna Township wreck was "buffing or slack action" and "train make-up" around the 121st position in the train as it was traveling at 35 mph down the track that evening.
Something went terribly wrong if "buffing (pushing) and/or slack (pulling) action" or "train make-up" lead to the derailment. That is an operational issues as opposed to equipment/track failure.

Four rail-borne risks moving through American communities

There is actually a lot more than 4, but the 4 are high tonnage, i.e., hundreds or thousands of tons (about 100 tons per carload). During grad school, I did a brief summary of chemical commodities moved through the university area (the railroad bisected the campus) because the local Transportation Institute had no such list. I just happened to watch trains and particularly tank cars moving through the area. For three years, I lived one or two blocks from the rail line.Edit/update: Video shows plastics from two hopper cars burning.
