It's easy to have vast amounts of pristine rail if you never wear it out by doing something crazy like "running trains on it". Seriously wtf is going on with that system - the last two interurban trips I tried to take on DB both involved going approximately to the city limits before getting stuck onto a coach bus because there was some massive technical failure that shut down the whole system. Like nah I'll happily take Amtrak over that shitshow. Sure it's slow and useless if you're trying to go anywhere that isn't between the country's largest metro areas, but it's reliably and predictably slow and useless. Moribundity you can count on!

(And non-sarcastically, even tho it sucks there's straightforward ways to improve it pretty rapidly. It's bad for sure, but it's still shockingly useful for the few areas it's able to be useful in. The incredible amount of overhauling that needs to be done for DB is... well, I'm glad it's not my problem to deal with because holy shit is that a mess. Starting from nothing does have some perks and, yknow, at least amtrak's radios don't melt when it gets a bit warm out)
