Just like Run 8. I think multiplayer would be a fun feature for this realistic train simulator. I remember in "The future of Train Simulator" video 2 years ago. I asked if there would be multiplayer on one of their youtube videos. And they answered it in The future of Train Sim video and their article on it. It states "Multiplayer is still heavily in development and will therefore not feature in the Train Sim World: CSX Heavy Haul Beta. However, we are planning for multiplayer to become a key feature of the Train Sim World experience and we’ll have more details on this in the coming weeks." We never got info in the coming weeks. Maybe this is what they are working on right now. We'll see what happens.
