Yeah, I own most of the U.S. routes and this one is noticeably better. It responds very well to turning on the Antialiasing-Transparancy in my Nvidia control panel to "Multi Sample". That really brings out the textures in rock faces, tree trunks etc.
It's funny, I wasn't going to buy it, but now I spend a tremendous amount of time there, and using the included ES44s to upgrade my retail version of Cajon Pass.
A person would be a fool not to buy the package with the BN and BNSF SD40-2s. It's a great combo, especially with Simmer4's sound pack in the SD40s.
