The train ride from Ulaanbaatar, Mongolia to Beijing takes 22 hours. There is no dining car and, coming straight from the Gobi Desert, we didn’t bring much food with us. At 11 PM we stop near the border between Mongolia and China. To our delight, the station has a small store so we stock up on chips, some bread, bananas - hallelujah! - and two cartons of noodles to which we can add hot water. We reuse the cartons to make tea.
