Eliminating stations is nearly impossible, for political reasons. There are ICE stops that are widely known to be just because an influential politician lives in that town.

That‘s also what happened with this new Berlin-Munich connections. The route makes little sense when you want to connect both cities as fast as possible. The detour only makes sense if you understand that the route needed buy-in from the states in goes through, and it was galling to state governments not to have their biggest cities connected, as well.

But it‘s not just influential elites. When Deutsche Bahn recently mulled killing the IC stop (not ICE - a category lower) stop in my town I was very unhappy. Fortunately they decided against it. But just from the plain numbers I can believe that it shouldn‘t have an IC stop.
