I bought this route in a 'Limited Edition' Bundle with an American Route 'Sherman Hill'. This is clearly the one I prefer though. The Settle to Carlisle Route is beautiful in real life & looks just as breathtaking in Train Simulator. I've been to both Ribblehead Viaduct & Garsdale Station in reality, and they're both rendered fantastically in this DLC. Not to mention that scenarios are plentiful - it's hard to complain about such a nice thing, but I've got two little not-quite-♥♥♥♥les...
Firstly, the AWS on the Class 66 is louder & clearer when you're on a Camera View outside of the Cab. This is incorrect, as you should only be able to hear it when you're in the cab. The other, again only a minor one, is that the steam engines in this pack should technically have AWS fitted if they're are Mainline-Certified. I don't mind though, the rolling stock in this scenario is fantastic.
For a start is the LMS Jubilee 'Leander' - this is a joy to drive, what with great chuffing sound-effects. It takes expertise to drive it on this route though, as they didn't call the Settle-Carlisle line 'The Long Drag' for nothing... the 4F is interesting, as is the scenario it comes with & for other passenger runs, you get the Class 158 DMU's in 'Northern Rail' livery. For the freight enthusiasts, there's the common Class 66 & the Class 37, both in EWS Livery. The Class 66, despite it's flaw with the AWS, is great to drive - again, a real challenge on this route even with an unloaded train. And the Class 37's are enjoyed by many, nick-named 'Tractors' because of the tremendous clag they make!
Overall, I'd say definitely go for this route. It's a looker, has great rolling stock & scenarios a-plenty - a fantastic slice of North England, rendered just as nicely as it is in reality.
