The Association of American Railroads has issued a safety alert for all railroads in North America.

The safety alert is to advise of the recent discovery of barbed wire found on safety appliances of a multilevel car.

This photograph was taken in the Quebec City, Quebec, area on March 26.

“Please distribute this information to coworkers, contractors, customers and all personnel who deal with these types of cars,” said James P. Grady, AAR assistant vice president for technical services.
