This route is rather fast, and part of the first transcontinental railway. Its pretty detailed, but the throttle on the EMD SD70M doesn't work, witch is a major bummer, the SD70 is one of my favorite engines. I like the new horns on the EMD SD40-2 and the GE ES44AC. Also comes with a SW10 switcher that's pretty descent.
Pros: -New Horns.
-Very fast and detailed.
-Part of the first Transcon, and is easily able to be 2015, or 1950 and every time in between.
Cons: -The double-stack cars aren't realistic
-Some of the rocks are a little sketchy
-Really boring for people with either no attention span, or aren't used to American trains.
Over all its a good rout for fans of the Union Pacific Railway. If there was a voting system, I would give it 7.5/10
