CN rainbow hoppers

[Forester1]

Saw some CN rainbow hoppers on a local N-gauge layout yesterday. Looking them up, it appears they were used about 1971? I had never seen them before, and I don't see any in Trainz?

Yes, that is the one I was referring to. Someone had a few on a CN consist at our local train club, along with some of the Saskatchewan and other Hoppers.
Thanks, PDKoester!
EDIT: I just looked up the formula on the side. It's Hexamethylene diisocyanate, or 1,6-Diisocyanatohexane, depending on which hit you pick.
