Any chance of locomotives from other nations?

Do you think there will ever be engines added to RRO that are not from America? I’m no expert and I know it’s deliberately set in America’s 1900s but I really would like to see a german addition, since the founder of the game is also German (me too). Although I believe all the noteworthy locomotives from here are built too late to fit in the game thematically.

What are your dream additions to the game?
