Service coordinators are assigned to long-distance trains. These trains go out west, and, on board, they have bars, dining cars, service counters, and so on. There are two positions, for the simple reason that the service director assigned to the train must at some point be able to rest. When the service director is resting, the coordination of on-board services is looked after by the service coordinator, who must be bilingual. So coverage is provided by bilingual staff 24 hours a day.
