Hello! thank you much appreciated!
As for your request, yes logitech is correct! I am currently working on the UP #844, a 4-8-4 FEF-3 steam loco. and after that I will attempt to bring the big boy UP #4014 into the game! Thank you for your offerings, I have already had a fantastic Big Boy model donated to me, I just have to get to it. Steam locomotives are very complicated and take A LOT of work to ingame compared to the diesels because of all the moving parts so they take a while to get into the game
