BRISTOL, Conn. (AP) - A train carrying construction equipment and scrap metal has derailed in central Connecticut.

Police in Bristol say at least six cars on the freight train came off the tracks near Riverside Avenue and Mellen Street at about 6 a.m. Wednesday.

There were no reports of injuries and police say no hazardous materials were involved.

Police Lieutenant Geoffrey Lund says most of the rail cars involved had open tops and fell on their left side, dumping at least a portion of their contents.

He says it's not clear how long it might take to clear the tracks.
