Train Sim And Train Sim World 2020 Compatability

I'm new to the forum and have recently purchased TSW2020. Are the DLC for Train Sim compatible with TSW2020? Working for Network Rail, there are some routes I've noticed available for Train Sim which I'd like to explore in TSW2020. Will they work or do I keep my hand in my pocket?

 

No, Train Simulator 2020 and Train Sim World 2020 are entirely different entities.

 

What you see is what you get with TSW2020... there will be no more routes to this game, it is now considered finished.
You can of course pay more money and get the new TSW2 due to come out in August...
