All these derailments lately likely are related to cuts of staff, maintenance, and regulation changes. It’s not a conspiracy like you might think.
That said always look out for ecoterror cells. In the PNW they have a 1/80 batting record with shunts. The Ohio train had fire/sparks for miles before it detailed.
@thendrix The one during the summer was due to thermal expansion which can be detected because they send signals through the tracks. The contraction from the cold after a hot summer could have shifted the rails. Despite the signaling and forewarning, a train derailed. Something smells fishy. There should have been alarms going off on the train and at the stations.
@thendrix It could have thermally decomposed to Chlorine and there is a good example of knowing when to walk away.
In Chemistry Labs where Fluorine gas is used, there's a very small period of time to remove the energy from the reaction. The building will be allowed to burn to the ground because nothing will extinguish an oxidizer that will likely burn asbestos.
If the Chlorine didn't react at the source, it would react elsewhere. Hydrogen and Chlorine react in darkness to make HCL but in UV light they react explosively to make HCL. Just letting it burn could have been the safest option. It will catch moisture in the air surrounding the area.
