The Nightjet trains from La Spezia (Italy) goes both to Wien and München, as it splits in Villach.
On the opposite direction, the train from München is coupled with the one from Wien.
Why is it not done more often? Because coupling trains is a security operation, and it takes time (1h+).
On top of that, modern trains are a fixed composition that you cannot couple and decouple as you like.
Note this concept was about a hypothetical design and infrastructure. That coupling would be horizontal and occurring while moving and using train designs that didn’t yet exist.
I said interesting, not necessarily practical. It’s something we might have tried to do if we didn’t have direct flights as a viable option.
