Now that Steam is allowing reviews of DLC, I'll start by reviewing this one. This is a great addition to the game. This route takes place in the deserts of California near the Mojave. It's a wide open and mostly flat route with long runs of high speed freight trains from UP, Santa Fe and BNSF liveries. There are some gentle rolling hills and the desert scenery is quite beautiful. The scenarios are all well done and completeable. There are over a dozen scenarios included. The best scenario in the pack is called "The Splitter" where you have to manually load some double stack intermodals with an overhead crane and then haul them to a staging point, drop them off, pick up another cut and proceed to a 2nd destination so there is alot to do and interactivity other than just driving the train.
It's a long route too, well over 100 miles end to end so it will keep you busy for quite awhile completing and driving the whole thing.
Performance is good, getting a solid 60fps pretty much everywhere on highest settings (PC specs below). Definitely recommend.
