I've found train travel sites can be fairly hard for non-locals to find / navigate through and you get waylaid by third parties that aren't as good for the actual booking as the less SEO optimized first-party carrier sites. Ends up being frustrating. I appreciate this site just gives you the facts rather than trying to do everything.
Everything about this is tastefully "old school". So much information density, and none of life story fluff most train travel blogs throw in.
I appreciate the advertising through fairly non-intrusive banners/links embedded in the pages (seriously, coming back in the HTML and not injected by JavaScript - who does that anymore?) that bypasses the adblocker. I was curious enough by the ones I saw that I disabled my adblocker to see if that was it - unfortunately there are also Google ads on top, but at least not cranked up to ridiculous levels.
I've "pinned" it in Kagi so now it comes up when I'm searching for train travel in the future.
