Station), and passengers on the Skyliner had to get off and take a bus from the station to the airport. This inconvenience caused many passengers to use direct city-to-terminal limousine buses rather than the Skyliner. Starting on September 1, 1979, the Skyliner began stopping at Keisei Narita Station once a day during the afternoon. This commuter-oriented service was expanded to become the Evening Liner service on December 1, 1984, and the Morning Liner was added on October 19, 1985. Nippori was added as a stop on the new commuter services, and in 1988, all Skyliner services began making stops at Nippori Station. Growing criticism of Narita ground transportation in the late 1980s led the Ministry of Transport to open up underground platforms and track initially intended for the Narita Shinkansen (a high-speed rail link between the city and the airport that was never built) for service by regular local and express trains. On March 19, 1991, the new Narita Airport Station opened directly underneath Terminal 1. Both the Skyliner and its new competitor, JR East's Narita Express, began service to the new station. On December 3, 1992, services began to Airport Terminal 2. Eight-car AE100 series trains were introduced in 1990. These trains were designed with emergency exits at each end, under the assumption that the trains would eventually be used for limited express service between Narita Airport and Haneda Airport: the Toei Asakusa Line has no emergency walkways along its sides, so it was necessary to allow evacuation from the ends of the train. Following the introduction of the AE100s, the seven six-car AE series trains were rearranged to form five eight-car trains. In June 1993, the older AE series trains were withdrawn from service. From December 10, 2006, most Skyliner services began stopping at Keisei Funabashi Station. 2010: Narita Sky Access opening From July 17, 2010, the Skyliner services were transferred from the Keisei Main Line to the Narita Sky Access route, with the introduction of new AE series EMUs. New Cityliner services using the older AE100 series trains replaced the former Skyliner on the Keisei Main Line. The new Skyliner service allows a transfer from Central Tokyo to Narita Airport in 36 minutes, 15 minutes faster than the old route via the Keisei Main Line, making it the fastest and cheapest limited express train option connecting Narita Airport with Central Tokyo.
