While riding the Empire Builder - and while driving from Dallas to Portland to get on the train - I saw a LOT of trains, and was pretty much surprised, I guess from my eastern perspective. The most common train I saw, both BNSF and UP, was containers - and most always with 2-3 locomotives in front and 1-2 in back. This didn't seem to matter if it was flat or mountainous. I NEVER see pushers here in the Kanawha Valley - lots of coal trains and grain trains, but no pushers. Also - I saw a lot of BNSF locos in the green/black scheme with BN logos. PLUS one small train that had a great looking BN caboose! Traffic seemed high too, was rare not to see a train.
