Still don't know what you you're talking about re: abysmal. The facts are

- the distance from Berlin to Hamburg is 282km, there are 33 daily train connections, taking 1:44h or more

- the distance from Berlin to Leipzig is 148km, there are 27 daily train connections, taking 1:26h or more

The real question though is, why would you want to travel through Berlin under all circumstances ;)
