I think hardly anyone would get off a train in order to eat, then get on a following train. At least in places like Japan and Europe, where a typical long journey is just a few hours.

It would mean arriving an hour (or more) later at the destination. It's usually preferable to eat at the destination, or make do with eating on the train (in a dining car, snacks sold on-board, or something purchased at the station or brought from home).

japan is small and europe doesn't do cross border rail well. I could see doing it onia boston to chicago trip (you have to get off in ny anyway) though really it only makes sense for trips where flying makes sense.
