The issue is not the lack of technical expertise. The structure of the German public transport system is very localized, due to its historical growth. local networks are often owned by the municipalities that they are serving, the actual busses are sometimes provided by private companies on contract, the national railway carrier has contracts with state governments and certain local entities for specific services, national, state and local governments are subsidizing various services, etc.

I completely agree that it is a mess, but it is not really easy to solve with so many stakeholders and so many (sometimes conflicting but valid) different priorities at stake.
