MTR Hong Kong Station is an interchange station in Central where passengers transfer between the Airport Express and the Tung Chung Line. The Airport Express runs directly to Hong Kong Airport, and the Tung Chung Line runs to Tung Chung. Following the Airport Express signs leads to in-town early check-in, where baggage can be checked in first, and the station has shops and restaurants. There are many stairs and few elevators, so moving with strollers or wheelchairs is inconvenient.
