PS5 Prerequisites For Main-spessart And Rhein-ruhr Osten Not Showing

The Main-Spessart... and Rhein-Ruhr Osten... are now coming with an interesting discount (on PS5).
Though I can't buy/install them as it seems needing some other routes, Locos, ... ?
Only it is not showing which ones, the lines are 'blank' and if you click one, it opens also a rather 'blank' screen.
So if anyone can tell me which ones would be needed ?

 

You don't need any other routes, but you do need TSW6 free starter pack. If you not claimed the TSW6 free starter pack before, you will need to buy a bundle, as the free starter pack was only available for free for a limited period of time. DLC marked as compatible with TSW6 can't be used on older versions of the game, like it was before with previous versions of the game.

 

Thx Lexie, though I have the free starter pack. As a matter of fact I was able to get the routes on TSW5 and after that they show in TSW6 as 'free', bu still not 'installable' or playable. When trying so it still mentions I need other stuff, but not showing me which ones ... the 'info' screen is merely blank ... e.g. Mainz-Spessart mentions 4 items needed, but they stay blank, I can circle through those 4 items, but selecting the m opens (again) a blank screen. (I've attached some pictures).

If you want to have the routes available in TSW6, you have to follow the steps in this guide: https://support.dovetailgames.com/h...nformation-for-PlayStation-Users-(READ-FIRST)

Routes don't need other add-ons, only the base game is required.
