The wreck was tanker vs tanker, with one car containing Acetone Cyanhydrin, two more containing Ethylene Oxide, and two more containing vinyl chloride..
The explosion that followed 2 hours later incinerated a trackside cannery, and poisoned nearby Buck creek killing fish and livestock for 50 miles.
