The Federal Railroad Administration fined Sperry Rail Service $25,000 (and CSX $25,000) after determining the Feb 2015 Mount Carbon, WV derailment was preventable, because Sperry's inspection equipment had flagged the rail flaw twice without the operator confirming it with a follow-up visual or hand test.
