The cars were removed Thursday, the (Worcester) Telegram and Gazette reported.
The train with three locomotives and 54 cars was headed for Worcester, Mass., from Gardner, a small city about 30 miles to the north. The last four cars of the train left the tracks and tipped over Wednesday afternoon near the point where the north-south Providence and Worcester Railroad line merges with the east-west Pan-Am track, Gardner Fire Chief Robert Therrien said.
The Providence and Worcester Railroad said the cause of the accident had not been determined Thursday. Charles Rennick, a spokesman, said the derailed cars will be moved to a yard in Worcester.
R.J. Corman Derailment Services had gotten two of the cars, including one blocking South Main Street, upright by early Thursday morning. But officials said the street would remain closed until the tracks were completely clear.
