Rare Train on the Chiyoda Line

EMU Tokyo Metro 06 series stands at Yoyogi-Uehara Station on the Chiyoda Line

I have already introduced the trains on the subway Tokyo Metro Chiyoda Line to you several times, but there are some left to do. One such train is the EMU 06 series, which I am going to show you today.

The Chiyoda Line was opened in 1969 as the sixth subway route in Tokyo. Connecting Yoyogi-Uehara and Kita-Ayase, the total operating length is 24 km. A total of 1.11 million passengers take this route each day. To operate this urban trunk subway line, a total of 61 sets of trains are required every day. They are covered by the Odakyu 4000 series, the JR East 209 and 233 series, the Tokyo Metro 6000, 16000, 05... and the 06 series. This 06 series is very rare train, because Tokyo Metro has only one set of the 06 series.

The EMU 06 series was launched in 1973 to reinforce the transportation capacity on the Chiyoda Line. The external design of the 06 series is similar to that of the 07 series being operated on the Yurakucho Line, but it must be remembered that the EMU 06 has the IGBT-VVVF inverter (variable frequency drive) control system, which was first adopted on the EMU 06 series in Japan.

Riding on the 06 series is my favorite thing to do. Owing to the high gear ratio of its driving system, I can enjoy the comfortable high-pitched tone of the electric motors. Am I a bit geeky?
