To supply a train, you'd probably need a helicopter service (no handy landing strips or airfields.)
I've never tried roast donkey.
I expect the North Korean dictator's staff had a schedule of his tour which probably went from city to city and could arrange for the food to be flown to the nearest airport to each daily stop and from there taken by car or truck to his hotel.
Once, when I was on holiday in Nice I saw, in a market, a Corsican donkey sausage (no jokes please!) It was a kind of salami, coloured black. I was curious but my girlfriend said that if I bought it she would never speak to me again.
