We need to know what industries have been using trains the most, and establish their weighted percentage amongst all industries.

I can tell you right away: Bitumen and Agriculture products.

Since 2010, pipeline development has been lagging behind production. Obama killed the Keystone expansion, then Trudeau came along and killed a few more expansion project. Since both CNR and CP they are former crown corps with a shit powerful left-wing union, they can label bitumen as "chemicals" or "petroleum products" and sneaked the cars through the entire continent with no environmental terrorism getting in their way since they are all leftists. But now with government laser-focused vision to destroy Alberta - we are being forced to cut production and hence less "petroleum product" shipments.

And now with the current trade war development, China's targeting all the agricultural products because they know Trump's got his votes from the Midwest and blue collar guys - including the farmers. China's also targeting Canadian farmers because of Huawei... they know that agricultural products e.g. pork, canola make up a huge portion of the Chinese-Canadian trade. You slow down the export and you cut agriculture products and of course you cut railroad traffic.
