Yeah that's the unfortunate side. Given the situation it makes way more financial sense for the consumer to take the plane ticket unless they enjoy the novelty of a long train journey.
Also had a situation recently where just a 1.5 hour train trip became 6 hours due to it breaking down in a town with few bus stops and no other trains, probably due to summer tourism. It would be nice if the rail infrastructure were even further expanded and tickets made cheaper to make it more competitive.
I also struggle with this often as a 'Merican expat living in another country, hopefully permanently. Occasionally I wanna catch up on US shit but most of the time I care more about what's going on in Europe and other places so I couldn't care less about the perpetually stupid shit happening back in the US.
I'm still learning the language where I moved to so English news resources that are about other places can be very valuable to me. My main resource (and advice to others with this issue) is using an RSS reader with good sources you find along the way. Not every site has RSS these days but many do. I fill in the blanks with podcasts and stories in the language of my country. Only downside is no discussion unless you post on Lemmy or other social media, but maybe that can become a thing we do. :)
