How would sawdust be hauled? Would it be in covered hoppers?
Wood chips on BC.

Thanks, but those are wood chips, not sawdust
I think sawdust will be carried in Presureaid/Airslide covered hoppers.
It would have to be in enclosed shipping containers, bags, or covered hoppers most likely. I don’t see any real big need for shipping by rail - in the “old days”, the local butcher spread it on the floor - as did the neighborhood saloon!! Today, it is more than often used on site - either burned for heat or to produce steam or electric. My [2c]
I would be surprised to find sawdust being carried in the raw state in a covered hopper. Best case might find palleted, bagged, sawdust carried in a boxcar. I really think, though, that most of the sawdust travels in a big truck to some local processing plant either for bulk distribution or bagging. I just don’t see the economics of loading a truck with sawdust, transporting it to some transload point to be put in a covered hopper, moved by rail to an unloading point, and then again transloaded to a truck for delivery to a processing plant. I think any processing is more likely to be done near the point where the dust is produced.
Anyway, following is a link to a discussion relating to the shortage of sawdust due to decreased lumber production: http://www.canada.com/vancouversun/news/business/story.html?id=35a4e55d-86ee-4ddf-a4d6-908791c66366
Over here in Norway, we transport sawdust in open topped hoppers, or in open topped small containers - three to a flatcar. Like this:

Here is some loaded cars - you can see the sawdust topped up over the edge of the open topped shipping containers:

No idea how it is done in the US.
