Sure, but if you miss your connection you can just take the next train. Frankfurt to Berlin might be impossible, but Hamburg to Berlin is manageable (4-5h), if money is tight, as is Hamburg to Sylt (3h) and many other connections in the 200-400 km range.

Assuming there is a next train.

Two weeks ago, the usual "person on the train line" cancelled all traffic for two hours, with the usual cascading effect for connections.

So instead of arriving at 7pm, I ended up reaching home about 10pm. I was 30 km away from home.
