Corporation subway (now: Tokyo Metro) Hibiya Line is a route connecting Naka-Meguro to Kitasenju. Vehicles on the Hibiya Line go from Kitasenju to the Tobu Isesaki Line, and the Sun Ray to the Minami-Kurihashi Bridge. Series 3000 trains were manufactured in line with the opening of Minami Senju Nakakachimachi in 1961, and 304 cars were manufactured by 1971. For many years nicknamed a sperm whale from the distinctive design of the rounded forehead, but gave birth to a series 03 due to aging, retired in 1994. Some vehicles are transferred to Nagano Electric Railway for active use. The product reproduces the later appearance of the 3037 formation. With the replacement of ventilators and doors, the figure is the most orthodox figure of the Hibiya Line 3000 series.
