Narita Airport Terminal 2·3 Station is shared between
East Japan Railway Company (JR East) and
Keisei Electric Railway. There is a common concourse on level B1F of the main Terminal 2 building and then platforms below, using double track originally intended for the
Narita Shinkansen. There is a security checkpoint between the station exit and the terminal building where identification (such as a passport) must be shown and baggage may be inspected. The security checkpoint is only connected to the Keisei side of the station, so JR passengers disembarking at this station go through two ticket gates: one between the JR and Keisei stations, and one exiting the Keisei station. A future renovation of the station is planned to streamline the exit process for JR passengers.
JR East JR East uses the eastern platform, which is to the side of a single track used for both inbound and outbound trains.
Keisei Electric Railway Keisei uses the western platform, a single island platform divided in half crosswise by a metal fence to form four numbered tracks. Tracks 1 and 2, on the southern half of the platform, are used for Narita Sky Access trains including the
Skyliner limited express service. Tracks 3 and 4, on the northern half of the platform, are used for Keisei Main Line trains. Passengers to the Main Line pass through two entry gates to record their use of the Main Line (which has a lower fare than the Hokusō Line). Passengers to the airport pass through separate exit gates to enforce the fare structure in that direction. Platform 3, used for Keisei Main Line trains bound for Tokyo, is only long enough to accommodate six cars; therefore two cars of each eight-car Keisei Main Line trainset open onto Track 1, the Tokyo-bound Narita Sky Access Line platform. Keisei has installed special signage in this section of Track 1 to warn passengers not to board these cars. ==History==
