Soda Ash Rail Shipping & Logistics: Rates, Railcars, Lanes
Natural sodium carbonate from the world's largest trona deposit at Green River, Wyoming — a one-origin commodity that rails everywhere glass is made.
Soda ash logistics by rail: what we do
Steel Wheel Logistics prices and coordinates soda ash carload moves nationwide — single cars and multi-car blocks — from routing and an indicative rate per car through car ordering, release and tracing to placement. Soda ash weighs out at 100–112 tons per car (roughly 58–65 lb per cubic foot) well before the car is full, so we size covered hoppers to the weight limit and the receiving track's capacity rather than to cube. Typical end uses are glassmaking (the largest use), detergents, chemicals, lithium processing — we confirm the receiving track and unloading method before the first car is ordered. Where the plant has no spur, we set up transload at a bulk transload terminal near the receiver and price the rail-plus-truck move against straight truck, so the mode decision is made on numbers. Demurrage control is planned rather than reactive: manifest cars arrive bunched, so we set release rules with the receiver and watch free time car by car. Shippers who need equipment can use our railcar brokerage to source covered hoppers on lease or per trip.

What it's used for
Glassmaking (the largest use), detergents, chemicals, lithium processing.
How it moves
Unit and manifest trains from Green River to domestic glass plants and to West Coast ports — one of the largest US rail export commodities by tonnage.
By the numbers: state rail plan figures
How much of this commodity group moves by rail, as published in the states' own federally mandated rail plans:
Statewide rail tonnage
- Louisiana: 5.9 million tons of potassium or sodium compounds moved by rail in all directions in 2021 (Louisiana State Rail Plan 2024, p. 60).
Single-direction figures
These count movement in one direction only — originated, inbound or outbound as each plan defines it — so they are not comparable with the statewide totals above.
- Missouri: 1.4 million tons of potassium or sodium compounds moved by rail inbound to the state in 2018 (Missouri State Rail Plan 2022, p. 50).
- Wisconsin: 888,108 tons of potassium or sodium compounds originated by rail in the state for an out-of-state destination in 2019 (Wisconsin State Rail Plan 2026, p. 136).
- Colorado: 504,960 tons of potassium or sodium compounds moved by rail inbound to the state in 2019 (Colorado State Rail Plan 2024, p. 38).
Each figure is quoted from the cited state rail plan and reflects that plan's own data year, commodity grouping and methodology — figures from different plans are not directly comparable with each other. Some plans count traffic passing through the state and others exclude it; each line says which.

Common questions
Can soda ash be shipped by rail?
Yes. Soda Ash moves regularly on the North American rail network in covered hoppers. Unit and manifest trains from Green River to domestic glass plants and to West Coast ports — one of the largest US rail export commodities by tonnage..
How many tons of soda ash 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 soda ash move in?
Covered hopper (~3,500 cu ft). Because the commodity is dense, smaller-cube cars are common — the weight limit governs.
What is the bulk density of soda ash?
Roughly 58–65 lb per cubic foot, depending on grade and condition.
Does Steel Wheel Logistics handle soda ash rail logistics?
Yes — we price and coordinate soda ash carload moves nationwide: routing and indicative rates per car in covered hoppers at 100–112 tons, car supply through our railcar brokerage, transload where the plant has no spur, and demurrage control.
