Railroads have used all sorts of cars in woodchip service, from regular boxcars (with or without normal doors), converted boxcars, gondolas and hoppers to purpose built hoppers and gondolas for woodchip service.

Hoppers were common in some geographical areas, but in many others gondolas (including converted boxcars and mill gondolas) were more common. (Please note and understand the distinction between hoppers and gondolas. I don't know why, but some people really seem to have a hard time with this for some reason.)

Mr. LMD Could you use the sawdust for mulch or other products?
Could you use the sawdust for mulch or other products?
No, mulch is made from woodchips (sometimes chipped bark). Sawdust is too fine. It would also simply blow away if you tried to ship it (even woodchips tended to blow out of cars in transit). Woodchips are used by OSB/chipboard mills and for pulp & paper-making.

jrbernier:
Anytime after 1934 they used it to make Prest o Logs. In the 1970's (?) it was chip board and later MDF (Medium Density Fiberboard). Also chips are used for OSB (Oriented Strand Board). The closer to current day the less likely they burned it . If they did, the earlier stuff was in the iconic wigwams. Later it would be in generator building for making electricity.
These are general statements that should help you. Did you have a specific era, local or company in mind?

Bangor and Aroostook converted a large number of old 40' box cars to wood chip cars by plating over the doors, removing the top, and adding side extensions like the green car below. These cars are kitbashed and sold by the Eastern Maine Model RR Club, see near the bottom of this pagehttp://emmrc.freeyellow.com/projects.htm

jrbernier Sawdust is usually burned at the mill. Chips can be carried in old box cars or in large 'chip' cars(sort of extra long coal hoppers) Here is a web link to some models of these cars: http://www.modeltrainstuff.com/HO-Scale-Woodchip-Gondola-Cars-s/2552.htm Jim.

Woodchips used to be carried in modified hopper cars too. Railroads would take old coal hopper cars and weld extensions on them - kinda like "regular" ore cars that had taconite extensions added. (Obviously woodchips are a lot lighter than coal.)

For their respectively freight car use, what freight cars carried sawdust and wood chips left over from the mill?
