Hamburg-Berlin route: renovation costs up to 2.2 billion euros. Route is to be fundamentally modernized from mid-June to mid-December 2025.

After the Riedbahn between Frankfurt and Mannheim, it is the second corridor important for long-distance passenger transport that is being addressed as part of the so-called general renovation. With the program, the railway wants to fundamentally renovate around 40 busy routes by 2030 in order to become more punctual and reliable.
