(Des Moines, IA) -- A union representing rail workers in Iowa is pushing for a new state law limiting the length of trains.
An Iowa rail worker union says a potential rail merger between Canadian Pacific and Kansas City Southern railroads could lead to more trains... and longer trains in Iowa.
A bill was introduced in the last legislative session but didn't go forward that would have set the maximum train length to one-point-six miles.
The union SMART-TD says they’ll be back at the Iowa State Capitol - with others to promote the bill.
The Iowa Department of Transportation says 18 private railroad companies are shipping freight across the state. The union says longer trains are more dangerous.
