I don't think you can conclude from overall performance of a complex system that a particular aspect of it (the way of electrifying tracks) is done wrong.

From what I understand, the problems in the German railway network stem predominantly from growing demand meeting the results of chronic underinvestment in infrastructure. That does not automatically mean that all of the work should be done in big chunks instead of continuously. They still could be doing some things right, and I think it is worth pointing that out. I find it more interesting and productive than blanket dismissal.
