A broken rail is the probable cause of a train derailment that caused hundreds of thousands of gallons of ethanol to be leaked last year.
A final report released by the National Transportation Safety Board (NTSB) confirmed beliefs that inadequate maintenance by Union Pacific Railroad played part in the March 2017 Siouxland train derailment.
The report also states Federal Railroad Administration inspectors didn’t do enough to identify flaws in the track.
Investigators say a broken rail caused the fiery crash near Greattinger, Iowa.
In total, 20 train cars came off the track. Out of the 98 loaded tank cars 14 released 322,000 gallons of undenatured ethanol which fueled a post-accident fire.
Nobody was injured in the accident.
