Four cars of a freight train hauling lumber and plastic derailed Wednesday morning.
Conrail officials say the cars remained upright and only caused minor traffic problems. According to Conrail officials, the train had left a Metuchen rail yard and derailed due to track problems.
Officials say no one was injured in the accident. The accident did not affect passenger trains. Conrail expects to have the freight train back on the tracks by the afternoon.
