The $1 trillion infrastructure and defense dund created by removing a constitutional brake in March 2025 opens the road to investment in an highly underfunded rail system in Germany which has parts of the system dating back to the 1900 period. First to be upgraded is the Hamburg to Berlin line which has the most passenger and freight traffic in Germany. One can see signs of this everywhere, landing at the Frankfurt main rail station one can see a building falling apart that dates back to the 1900 period, that is a sign of the way infrastructure was neglected in Germany till now.
The economic growth under Merkel was somewhat of a mirage as it was dependent on the automobile industry with little investment in renewable energy technologies, dependence on lower priced energy from Russia, huge neglect of infrastructure and childcare, and lack of future vision for Germany.
