A minor fire caused delays on an Amtrak train headed for Chicago Tuesday night.

The Amtrak train was headed to Chicago from Milwaukee when a minor electrical fire was reported, according to the Chicago Fire Department.

No injuries were reported when the train was stopped at Kilbourn and Milwaukee in the Irving Park neighborhood, the fire department said. A battery on the train was believed to be the cause.

A spokesman for Amtrak said a mechanical component of the train overheated and the fire department was called. The train had 39 passengers on it at the time.

Passengers were transferred to a Metra train to complete the trip.
