Didn't know overnight trains had disappeared. When I lived in Europe as a poor student from the US I would take night trains every single time I could. I had an Interrail pass and once everyone was settled down for the night go look for an empty seating or sleeping area with a door. I could usually find one and then I would just lay down inside with my feet agains the door, use my pack for a pillow and go to sleep. I traveled a month like that and never paid for a hotel.
