The 2002 Farragut derailment occurred on the morning of Sunday, September 15, in Farragut, Tennessee. Norfolk Southern freight train 15T derailed 27 cars, resulting in the release of oleum or fuming sulfuric acid. Roughly 2,600 residents were evacuated from nearby homes for three days until hazardous materials crews were able to mitigate the scene. No fatalities or major injuries were reported as a result of the derailment, but property damage and losses were calculated at US$1.02 million. == Background == On the morning of the derailment, Norfolk Southern train 703 approached the spring switch at the west end of the Boyd Siding and was given a signal restriction. The crew of 703 stopped in the siding and examined the spring switch at the east end of the siding, noting a 1/4-inch gap was present between the switch point and the stock rail. The crew manually operated the switch several times and noted that the switch still had a small 1/8-inch gap. The 703 engineer radioed Norfolk Southern dispatch to report the issue. Train 703 then proceeded through the switch without incident. A maintenance person was sent to investigate the report, arriving at the site around 11:00 AM EDT. He observed that the signals were clear and that the spring switch appeared to be properly aligned against the rail, likely having completely closed after train 703 passed through the switch earlier. The signal maintainer later told investigators that he felt the switch "looked like it could use a little oil".〔 The signal maintainer checked with the dispatcher to obtain a track warrant so that he could perform work on the active rail line. He was informed that two trains were approaching the siding and decided that once both trains passed the area he would obtain the warrant and perform an internal inspection of the switch. The signal maintainer was waiting in the immediate area of the switch as train 15T approached from the east and observed a clear signal on the switch.
