Salt by Rail
Rock salt from Midwest and Gulf dome mines — the road-deicing supply chain runs on rail and barge positioning done months before the first storm.
| Railcar | Covered or open-top hopper |
| Typical net load | 100–112 tons per car |
| Bulk density | ~72–80 lb/cu ft |
| Loading constraint | Weighs out (weight-limited) |
| STCC | 28991 — look up related codes in the STCC Finder |
What it's used for
Road deicing (the big tonnage), water softening, chlor-alkali feedstock, food.
How it moves
Mines to municipal and DOT stockpiles across the snow belt, mostly staged in summer and fall. Deicing salt can ride open-tops; evaporated and food grades need covered cars.

Common questions
Can salt be shipped by rail?
Yes. Salt moves regularly on the North American rail network in covered or open-top hoppers. Mines to municipal and DOT stockpiles across the snow belt, mostly staged in summer and fall.
How many tons of salt fit in a railcar?
A typical load is 100–112 net tons per car — the car reaches its weight limit well before its cubic capacity.
What railcar does salt move in?
Covered or open-top hopper. Because the commodity is dense, smaller-cube cars are common — the weight limit governs.
What is the bulk density of salt?
Roughly 72–80 lb per cubic foot, depending on grade and condition.
