As I've enjoyed playing train sim on ps4, it would be nice if the CSX heavy haul could still make an appearance. Maybe some assets from it like the SD40-2 and AC4400CW. On the ps5 it could be added. I would like to see more immense USA rail freight routes from CSX, Norfolk Southern, Union Pacific, and the BNSF, Class 1 railroads and maybe add class 2 railroads with more freight missions and less passenger for a change. With that said, it be nice to add locomotives and cars from predecessor railroads Like Conrail and the railroads that it Consolidated in the north eastern part of the USA. In my state i live next to a NS track. It would be awesome to have it featured in a US freight route expansion. Multiplayer added to the game would be a unique feature. Have a server open to take a freight train, for a example from Conway, PA to Miami FL or from PA to CA or anywhere in the US. Have a computer control signals or human controlled and you must stop and wait for another players train to pass before your given clearance to proceed.You can ride solo or have a friend ride with you in your train. It would be the at most realistic virtual railroad experience. Long freight and passenger runs, save points for players progress. It would be railroading at its finest with platform crossplay from all over.
