This nice essay from Escalation Consultants, delivered on 5/21/2020, shows very large decreases in rail carloads after mid-March of 2020, approaching 30% for most carriers. Only Union Pacific is down by only 18%.
Another graph shows the differences by commodity.
Only grain and crushed stone are up. Coal and petroleum, the profit centers of the railroads, are way down, by more than 30%.
The article claims that one can take advantage of leverage to obtain favorable prices due to these steep declines in the Coronavirus economy.
I think the article bespeaks some hard times ahead for the big rails.
