A necessary step
This work is part of a comprehensive program to modernize and renew the rail infrastructure in Germany. According to a response from the federal government to a request from the CDU/CSU parliamentary group, the main reason for the frequent delays is the overloaded and fault-prone rail infrastructure (see Bundestag ). In order to increase punctuality, a comprehensive renovation of the rail network is being planned.
Work on the victory route is now in its final stages, which will lead to additional restrictions from the end of November 2024 as trains are canceled and have to be rerouted.

The aim is to make funds available next year for path price subsidies in long-distance rail passenger transport and rail freight transport. In addition, the electrified route network is constantly growing and is expected to grow by a further 70 kilometers by the end of 2025.
