CN Cylindricals

Does CN use some round hatch cylindricals in Grain haul or are they restricted to fertilizer service?

thanks,

Grain hoppers use trough hatches.

I know most of the time its trough hatches, but do they ever mix them?

As far as I am aware the round-hatch cars are strictly in fertilizer, potash and cement service. Such cars would not be re-used for grain because of residue concerns.
