There’s a nasty curve on NS in Gainesville VA where I live. Tracks are about 30 feet atop an embankment. Directly below is a trailer park. Also nearby is a propane company and 3 gas stations. Several trains have derailed in the last few years. One took out a gas station, severely injuring or killing one of the workers. Another time, tank cars loaded with propane overturned there, fortunately at very slow speed. Trains routinely run thru here doing 50 or 60 mph.
Just a matter of time.
