In England we don't really have the same idea of train. They're for shorter commutes and not the typical big sleeper ones. My first experience on one of the sleeper ones was taking it from Yerevan to Tbilisi a few months ago. I loved it. Such incredible views and such a fun experience. I recently took another short trip, one from Tbilisi to a small former Soviet resort town called Borjomi. A shorter trip but similar type of train. Old, rustic, loud, and full of interesting characters.
I definitely prefer this form of travel to getting the car or a bus, or even flying. Feels so much more connected with the world and the space around you. I think it's a great experience but also lesson about yourself, for if you can deal with the downs of a long trip on a sleeper train, you can handle most things!
And we have these food vendors coming every now and then serving some hot crispy food that makes it fun.
