In the USA Strasburg Railroad would be a very viable option. I personally would like a large mainline steam locomotive. Specifically the Norfolk and Western 611. It has operated at Strasburg along with their own fleet I would like to see the #90 and #475 As a route its not all that long or exciting, but for a place to operate various locomotives it would be pretty good. They have one of the best respected Steam restoration shops in the USA and do a lot of contract work for other railroads. I think they even worked on the drive wheels from the Big Boy. The Reading and Northern Railroad would also be a great option as they have two operable steam locomotives. Reading 2102 is just completing restoration and the 425 is a classic. It is a much longer route, and you can actually get up to a good speed. The 425 stack talk when running upgrade is pretty impressive. They also are a really great short line freight operation. They haul a lot of Anthracite Coal. I believe they would be an excellent addition as well. Either of those two routes would be great. I am definitely hoping for a large mainline steam loco in the game for sure. I am a big fan of 4-8-4’s they are designed for speed and power and are quite impressive. Adding a Challenger to the Clinchfield would be pretty awesome as well! I think it would be really great if they could work with some of the organizations that preserve these locomotives in the USA. They are always struggling for funding, and with new rules there are not a lot of mainline steam excursion here anymore. I think the people involved in those groups would love a simulated version of the locomotive, as well as getting the organization out to a wider audience. Some model railroad companies have collaborated with various groups and donated some of the sales to the preservation organizations to help keep the real locomotives running. I will be happy with any US mainline steam, I’m really hoping for 611!!
