> Look at how much Switzerland spends per capita vs Germany. €477 vs €115

Your chart shows close to €200 spent by Deutschland per capita in 2024, before the abovementioned spending splurge (about €30/person/year). (The numbers 477 and 115 never appear in your source.)

€230 in Berlin purchases about as much as €371 of CHF in Zürich [1]. So no, I’m not seeing evidence Germany needs to further 3x capital expenditure to unfuck its system, and that’s before observing it spends more than Italy per capita, and Italy’s intercity rail is fantastic.
