The twitter post is incomplete. It’s all local and regional transport - including regional trains. Regional trains can run for a few hundred kilometers, for example you can do Kaiserlautern to Osterburken (close to Würzburg) without changing. That’s about 200km. There are a few confusing exceptions where long distance trains run under a regional code.
