Montana Rail Link (MRL) is a Class II regional railroad company that operates more than 900 route miles of track in Montana and Idaho. Goods shipped by Montana Rail Link include coal, industrial products, grain, intermodal and vehicles. The State of Montana has major swings in climate conditions and soils and environmental influences that can be aggressive to steel and concrete structures, which is a concern for MRL. The company’s inspection group continuously reviews their infrastructure and identifies required structures and rail repairs.
