I’ve never seen it before but were just given examples, DSB being one.
I find it strange to manage tickets separate from seats. Why not keep them linked?
It’s mostly because you can have tickets that are not bound to a specific train. Aside from things like monthly tickets you can also have tickets for a single ride, which have a fixed start and end station, but you can take any train on the booked day. When you don’t know beforehand, which train you will take, you can still reserve a seat as soon as you decide (even just before the train leaves)
You can make the reservation independent of the ticket/fare payment. You’re still supposed to have a ticket for the class of service you want.
Paying for a seat reservation doesn’t pay the ‘fare’

Because of things like monthly regional passes.
those are a different kind of train where i live. regional trains have mostly passes (that also work on buses), intercity trains do not.
