Design

The 9000 series trains were built between 1993 and 1999 at Seibu's own Tokorozawa Factory by combining electrical equipment from former 101 series EMUs with new steel bodies based on the New 2000 series design.[2] These were the last trains to be built at the Tokorozawa Factory before it closed in 2000.[2]

History

The first train entered service in 1993, with eight 10-car sets built by 1999.[2] The fleet was refurbished between 2004 and 2008, with new underframe equipment and VVVF inverter control.[2] Refurbished sets are identified by stickers on the cab end doors.[2]

Tamako Line transfer
Set 9102 in July 2023

Beginning in 2020, the 9000 series fleet was shortened to four-car formations and modified to accommodate driver-only operation for use on the Tamako Line. The first of these sets was set 9108, which entered service on the Tamako Line on 1 October 2020.[4] As of 15 June 2021, the entire fleet has been modified for Tamako Line operation,[5] excluding sets 9101, 9106, and 9107, which were scrapped beforehand.[1]
