NTSB Preliminary Report RRD23MR005 Norfolk Southern Railway Train Derailment

[Hiawatha Pete]

23. Railroads carry dangerous goods because they are required to by law.

FYI bearing temp is a function of speed - speed goes up, temp goes up. At about 50mph a normal temp could well be around 100F above ambient.

What isn't mentioned is the fact that after a stopping to inspect, crew must proceed at restricted speed until a favorable reading is reached.

Also, wrt detector intervals, it's about the same as Europe: https://publik.tuwien.ac.at/files/pub-bi_5916.pdf In many instances detectors are only a few miles apart.

The NTSB will determine the best course of action - whatever that may be. They have an entire team of extremely well qualified specialists & engineering professionals.
