SALISBURY — Norfolk Southern Railway has moved three locomotives that derailed Sunday off West Innes Street.

The train derailed behind Sherwin Williams paint store at 12:40 p.m. Sunday. One of the locomotives had a small diesel leak.

“It was a minor leak,” said Susan Terpay, Norfolk Southern public relations director. “It has been remediated.”

After Norfolk Southern removed the three locomotives with a crane, the railroad began assessing track conditions and will begin repairs to restore rail service on the line. Terpay said Norfolk Southern has two sets of tracks in this location and has continued to operate trains on the second track.

Terpay said the cause of the derailment is under investigation.

Crews initially said the derailment was due to the railroad tracks being washed out.

On Sunday afternoon, McElroy advised residents within a mile radius to stay inside as a precaution.

Norfolk Southern worked with the Salisbury Fire Department, Salisbury Police Department and Rowan County Hazmat Response Team to clear the derailment. Shamrock Environmental Corp. was brought in to assess the fuel leak.
