History The 2000 series trains were introduced on local train services on the Seibu Shinjuku Line in 1977, featuring four pairs of sliding doors on each side to speed up boarding and alighting at stations, and they were initially formed as six-car sets.
The last early-model 2000 series eight-car set, 2007, was withdrawn in April 2022. Train set 2055 (a first generation six-car set) was manufactured in January 1989 and was set with a vehicle number of -10 in September 1991 and became 2045 in order to avoid number depletion due to the increase of eight-car train sets. A new eight-car set, 2055 (second generation), was manufactured from December 1992 to March 1993. This second-generation set 2055 was manufactured after set 2097, and this is the final train set of the new 2000 series.
Transfer to Ohmi Railway In 2025, multiple two-car sets were transferred to Ohmi Railway, a wholly owned subsidiary of Seibu. The first of these sets began service on 18 November of that year.
