SUPERIOR, WI (KDAL) - The Superior Fire Department responded to a conveyor belt system fire at the BNSF Allouez Taconite Facility on Monday night. The system is about 80 feet high and 1000 feet long and is used to load taconite onto ships at the dock. Fire crews were hampered by the height of the structure and also visibility problems because of smoke and the weather. They eventually found and extinguished the fire. The cause is now under investigation by the railroad and damage amounts are also pending.
