Map of Railroads With Most Tracks in Each State; where can I find it?

Recently, I remembered seeing a map in Trains Magazine. It showed which railroad had the most track in each US state - for example, Norfolk Southern was said to have the most track in Ohio, CSX in Virginia, UP in Colorado, BNSF in Arizona, etc.

I was wondering if anyone could maybe direct me to where I could find this same map online. It’s part of an alternate history project or tow I’m doing right now.
