Seibu 9000 series

Data (as of 12 Jan 2024)

History

The 9000 series trains were built with N2000 series-like bodies and 101 series' motors, traction, braking systems and bogies. Eight ten-carriage units were introduced to Seibu Shinjuku and Ikebukuro Line, and the eighth unit was the last train that was built in Seibu's own factory. All units were allocated to Ikebukuro Line by 2000. Those electrical equipment was replaced with new one in 2003-08, which allowed higher maximum speed and less energy consumption.

Following the introduction of 40000 series, three units were scrapped in 2017-18, while other five units have been shortened to four-car units and reallocated to Tamako Line. They were reinstated to mainline use in 2020-21.

Current Operations & Future Prospects

Five four-car units are used on Tamako Line, and all of them are compatible with driver-only operation. The third unit is painted red, while the eighth unit is painted dark blue.

When the 9000 series were used on Ikebukuro Line, there was a sticker on a front gangway.

In 2013, Seibu repainted a unit red and white, as if being a Keikyu train. It was called "RED LUCKY TRAIN".

It now runs on Kokubunji Line but repainted red only.

It also runs on Kokubunji Line today without decorations.

In 2016, a unit was repainted pink and named "KPP TRAIN", a promotion with Kyary Pamyu Pamyu (a singer and model).

The pink train ran Ikebukuro Line for a while even after the promotion was finished, but it was scrapped in 2018.
