|Type 600 (4- and 8-car fixed formation, car length 18m)
Type 600 was introduced in April 1994 as a passenger train between Oshiage and Sengakuji stations on the Asakusa Line of the Toei Subway, between Oshiage and Sakura stations on the Keisei Electric Railway, and between Takasago and Inba Nippon Medical College stations on the Hokuso Railway. The main controller is VVVF inverter control system (1C8M system) with GTO thyristor elements, and the main electric motor is KHM-1700 type cage type three-phase AC in duction motor (120kW).

|Type 1000 (4-, 6-, and 8-car fixed formation, car length 18 m)
The 1000 class is a train with an impressive musical scale (Do-Re-Mi), which is a unique Siemens magnetic excitation sound when starting up, and started commercial operation on April 15, 2002. This train is 18m in length and has three doors on each side, which is the standard for the Asakusa Line of the Toei Subway.
The exterior design is based on the three-dimensional curvature of the 600 and 2100 series, with an emergency plug door at the left end of the front.
The VVVF inverter control system for the first and second trains uses a GTO thyristor device manufactured by Siemens of Germany, as does the 2100 Series, and the main electric motors are equipped with cage-type three-phase AC induction motors.
The 3rd to 5th cars were also manufactured by Siemens, but the elements used were changed to IGBTs and pure electric brakes were installed. The VVVF inverter control unit, current reductor, filter reactor, and other components are all housed in a single box called a “traction container”. The specifications of the main electric motor are the same as those of the 2100 class, and it is a cage type three-phase AC induction motor ( 190kW) manufactured by Siemens.
The specifications of the on-board equipment have been reviewed, and when the trains are renewed, the inverter equipment will be replaced by a Japanese-made inverter, and the musical scale (Do Re Mi) will no longer be heard. The equipment has already been changed from the 6th car in 2007. If there is no indication “Powered by SIEMENS” on the production nameplate inside the car, it is a renewed car.
The former 1000 type that was out of service or scrapped is here ( retired car).
|Seibu Railway and Keihin Electric Express Railway decided to use each other’s symbol color for their trains, and Keikyu started to operate one 1000 Series train with 8 cars as “KEIKYU YELLOW HAPPY TRAIN” on May 1, 2014. Seibu also operates one 9000 Series train with 10 cars as the “RED LUCKY TRAIN”.|

|Type 1500 (4-, 6-, and 8-car fixed formation, car length 18m)
The 1500 class started commercial operation on April 1, 1985, and became Keikyu’s first VVVF inverter-controlled car. After that, some of the trains were converted to the maximum operating speed of 120 km/h, and a total of 166 cars were manufactured by 1991.
The main control system was converted from armature field chopper control to VVVF inverter control and the main electric motors were converted to cage type three-phase AC induction motors between 2006 and 2009. This train series was manufactured to serve the Asakusa Line of Tokyo Metropolitan Transportation Bureau, Keisei Electric Railway, and Hokuso Kaihatsu Railway, and adopted the T type one-handle mascot based on the agreement for transit.

|Type 2100 (8-car fixed formation, car length 18m)
The Type 2100 is a train with an impressive musical scale (Do-Re-Mi), which is unique to Siemens and was put into commercial operation on March 28, 1998. The main controller is the SIBAS32 VVVF inverter control system “Traction Container” (photo #8, bottom row) with GTO elements manufactured by Siemens of Germany, and the main electric motor is a cage-type three-phase AC induction motor.
The specification of the installed equipment has been reviewed since 2008, so when the trains are renewed, the inverter equipment will be changed from Siemens to Japan-made, and you will not be able to hear the musical scale (Do Re Mi) anymore. The sound scale (Do-Re-Mi) can no longer be heard. If there is no “Powered by SIEMENS” on the nameplate inside the car, the inverter equipment has been replaced by Toyo Denki equipment.
