Blow off of Sand from Railways
A company manufactures lightweight rail cars for transporting people, equipment, etc. Sand collects between the flangeways and builds up on the rails. This buildup can cause the cars to de-rail. Two pieces of a Model HP1002SS Stainless Steel High Power Safety Air Nozzle, one for each side of the rail, will have enough force to dislodge the sand, and blow it off the rails, out of the way of the moving rail car.
