A CSX Corp. train carrying liquefied petroleum gas (LPG) derailed early last Thursday in Wetzel County, WV, but no injuries or propane leaks were reported.

Six cars went off the tracks at a rail yard in New Martinsville, about 50 miles south of Wheeling, and four tipped over, CSX said. The cars were not damaged, but it remains unclear what caused the derailment. Both CSX and the Federal Railroad Administration are expected to investigate the cause. First responders said the incident did not affect nearby neighborhoods.

The incident occurred at about 2:45 a.m. EST and forced the company to shut down the stretch of tracks. Public safety officials said no gas leaks were discovered and added that the cars had a double steel casing that likely prevented any leaks.

LPG deliveries via rail in the region have increased with the rise in natural gas liquids production from the Appalachian Basin. Earlier this year, a 109-car CSX train carrying Bakken Shale crude oil derailed in the Mount Carbon area of West Virginia, about 35 miles southeast of Charleston. No injuries were reported, but about 19 rail cars exploded after they derailed (see Shale Daily, Feb. 20).
