Fix the ai trains passing signals at danger and try to incorporate some varied rolling stock and possible for all platforms add the refueling process to loco preparation services and more shunting services unless the are reserved for a later tank engine dlc.
With manual firing not being a thing yet, it's unlikely we'll see any steam until there implemented. You can only get varied rolling stock through loco dlcs which are other steam trains, but due to issue above, they probably won't any time soon.
But next gen consoles have rolling stock like the red and cream mk1s and stuff like vans and mineral wagons.
I believe its got something to do with performance on 8 Gen Consoles. Mixed rolling is in all versions of SoS as I have seen mixed goods trains as well as the B&C MK1s in both Scenarios and during the Training Modules as well as in custom scenarios. I play on Xbox One S which is a Gen 8 Console
