Steam Curious About Converting Some Locomotives!

So, I have a copy of TSW 2020 for the PS4. And I recently just got TSW 5 (for steam) and I want to convert some of the locomotives I had on there. Like the CSX GP38-2 and the AMTRAK ACS-64... But I don't know how to do this as I NEVER made a Dovetail Live account on TSW 2020. Can someone help me?

 

DLC are not cross-platform compatible. Steam, Epic, Sony and Microsoft are competitors and want you to buy via their platforms and stay there so that they get a piece of the pie. If you want to play your PS4 DLC on Steam, you have to buy them again on Steam.

 

Ok Thank You, I just don't want to buy the ACS-64 again but I guess I have to if I want it.
