PS5 Bakerloo Line Expansion Not Loading In Tsw4

Hi Dovetail Games,
Is there any word of the Bakerloo Line Expansion working with TSW4 as I used to love driving that line and since buying TSW4, I can't play it.
Sure I can download it, but it won't load. I can see the train stock on the my trains screen, but no other content is available.

Can you help please?

 

Make sure you downloaded the correct version of the DLC. If you download the PS4 DLC on PS5, the PS5 game is not gonna see it.

 

I played it on the PS5 in TSW3 and imported it along with all my owned levels. However TSW4 isn’t importing any of it.

 

Here is what Dovetail Support says to do about missing add-ons. If that doesn't work for you maybe make a ticket on that same website in order to get support from them directly.
