Type AE (New Skyliner)
|Type AE [New Skyliner] (8-car fixed formation, car length 19m)
The AE class express train was introduced for the “Narita Skyliner Access” that opened on July 17, 2010, and achieved a maximum operating speed of 160 km/km on conventional lines. The train consists of eight cars with a MT ratio of 6M2T, and uses Toyo Denki’s RG6009-A-M type VVVF inverter control system with constant speed operation function.
The train was designed by Kansai Yamamoto based on the concept of “Wind and Rin” to create an innovative design with a sense of speed.
The first train, manufactured by Nippon Sharyo, was delivered in May 2009, the second train, manufactured by Tokyu Sharyo, was delivered in December 2009, and the fourth and sixth trains, manufactured by Tokyu Sharyo, were delivered in January 2010.
A new 10.7-km line (from Inba Nihon Medical University Station to Tsuchiya, Narita City [Narita Airport Rapid Transit]) was constructed to extend the Hokuso Line, connecting it with the Keisei Main Line from Takasago Station, reducing the time required to Narita Airport to 36 minutes (36 minutes between Nippori and Airport Terminal 2 Station, 44 minutes between Keisei Ueno Station and Narita Airport Station), 15 minutes less than the outbound journey time. This train line received the 2010 Good Design Award from the Japan Industrial Design Promotion Organization, and also won the 2011 Blue Ribbon Award from the Japan Railfan Club. The official announcement at the time of opening is here.

|Type 3600 (6- and 8-car fixed formation, car length 18m)
The Type 3600 was built between June 1982 and July 1989, with a total of 54 cars in nine 6-car trains.
It was the first Keisei train to be equipped with Toyo Denki armature chopper control andDC DC direct-wound motors, and a T-type one-handle mass controller was used as the main train controller. The car body is lightweight all stainless steel construction.
|Type 3700 (6- and 8-car fixed formation, car length 18m)
The 3700 class started operation in March 1991. It was the first train to adopt Keisei’s VVVF inverter control system. The control system is the 1C8M system, in which one controller controls eight cage-type three-phase AC induction motors.
A DC-DC converter using a GTO element is installed as an auxiliary power supply, and a reciprocating AC power-driven air compressor is installed as an air source unit. This train can be directly connected to the Asakusa Line of the Toei Subway, the Keihin Electric Express Railway lines and the Hokuso Line.
