A 66-year-old railroad conductor B.W. Cox said that CSX Transportation was to blame for his interstitial fibrosis diagnosis. After cabooses had been discontinued, Cox would follow behind the locomotives in a trailing unit where he was exposed to substantial diesel exhaust. Although CSX said that cabooses being discontinued posed no medical hazards, Howard Coker and other attorneys at Coker Law argued that CSX had not taken any preventative measures to limit exhaust exposure to their employee. CSX was found to be at fault for employer negligence and Cox was awarded $3.5 million dollars.
