I almost didn't buy this route because I have Marias Pass already, but I saw it on a Twitch broadcast this week, and after watching a scenario on it, decided to buy it especially since it is on sale for 40% off. Am I glad I did, the scenery is spectacular and there are loads of free scenarios for it at the workshop. I also got the SP SD70 and SP Sd45 on sale at the same time, which adds alot to this route as far as the scenarios you can run. I give it an B+.
The only negative is the career Scenarios. Don't expect to get any positive points when you run some of them like "Getting Involved". There is no way you can run the scenario on time and score points, because the time alloted isn't long enough and the train won't go fast enough anyway. /
