A train derailed on Johnson Street in Middletown, near the Middletown Recycling Center, which is the city dump.
Middletown Mayor Daniel Drew said at least eight cars went off the rails on a section of state-owned railroad tracks that Providence & Worcester Railroad leases from Connecticut.
Freight trains use this section of track and the train that derailed was carrying steel, according to the mayor.
No one was injured and there is no hazmat spill.
There was a small derailment in the area five years ago on Halloween and tracks in the whole area had to be repaired, Drew said.
