Can you name a system that moves roughly the same amount of freight as the US while still having excellent passenger service on the same rail infrastructure? Genuinely curious.
On literally the same rails, I suspect that doesn't happen that much. China moves more tonnage by rail freight than anywhere else in the world, and it has an immature-but-excellent-where-it-exists high speed system, but it doesn't generally share lines with the freight.
80% of freight is done by rail in Sweden I know nothing about logistics so this is just first hit on Google, I do not make the point to contradict you. I think the issue here is how you split up the big numbers into managable percentages for easy statistics, I'm guessing there is a lot of issues when you are talking about this. The biggest is that the US has spent 70 years of lobbying from car manufacturers and oil companies to make people use cars, that has left a scar all over the world. Not only in the freight vs. passenger statistics.
Another aspect that needs to be taken into account is that a large part (perhaps 40%) of any number you see on total tonnes of rail freight in Sweden, is made up of handful of short rail lines doing nothing but transporting iron ore from a few large mines to the nearest harbour.
It's true that the US moves more freight by rail compared to for example EU. But that doesn't mean the reason for this is the mostly excellent passenger rail system in the EU. I'm not an expert here at all, but for example this article cites a few plausible reasons: https://www.freightwaves.com/news/why-is-europe-so-absurdly-...
As your link shows, money that is spent on making a good freight rail system is mostly money that doesn't help with passenger traffic.
You claimed that there were "many" countries that had both good freight and passenger rail, but have yet to come up with one. (Sweden isn't an example - its "good freight" service (mines to ports) is where there's insignificant passenger service.)
