DB the company has a lot of foreign interests. It bought a British transport company in 2010. Why did they do this instead of reinvesting the money back into the Deutsche Bahn? Because it’s a joint-stock company beholden to stake-holders. It should never have been managed like a private company. Now the damage is done and decades of unrepair is catching up to them.
Somehow I don’t blame the politics for this disrepair. I blame the execs and upper management.
