Once the steam core is tested, and if it works. I would like to see a route with steam somewhere along the N&W's mainline from Norfolk,VA to Roanoke,VA. The route consists of mostly the same type of mallets (class A and Y6) and would allow us to also drive the class J. It has a lot of variety, speed, and power for both freight and passenger services.
You can post this in the Suggestions subforum, I think the developers will read it with a higher chance there.
DTG have said that they take into account the amount of interest in a route suggestion when deciding routes to cover. So, I agree with dreampage. You should put this is Suggestions forum when peoples interest will more likely be considered by DTG as that is where they will look for it.
