History

The first trains entered service in 1977 on the Seibu Shinjuku Line, initially formed as six-car sets.

The last early-model 2000 series eight-car set, 2007, was withdrawn in April 2022.
Train set 2055(the first generation, 6-car ) was manufactured in January 1989 (Heisei 1) 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 8-car train sets, A new 8-car 2055 organization (2nd generation) was manufactured from December 1992 (Heisei 4) to March 1993. This second-generation 2055 organization was manufactured after the 2097 organization, and this is the final organization of the new 2000 series.

Renewal

From new 2000 series train sets that were more than 20 years after they were made, a renewal and some fixing of the parts were started. The first renewal was made to the train set 2047 (6 cars) and started renewing in December 2007 and finished in March 2008. The renewal contents are:　

Exterior

* Changing the pantographs to Single-arm type.
* Making the part that shows the destination of the train full-color LED.When it was refurbished, it is still not full color-LED, but it was made full-color LED afterwards.
* In the front, there made a plate that indicated the train set's number (example, 2077).
* On the side, they changed the part that shows the number of the train set to a plate and removed some windows.
* To stop passengers from falling into the train tracks, in some of the train sets, they placed a speaker that warns passengers.
* Exchanging the horn.

Interior

* Making the floor rug to a grey rubber and in places close to the doors, the color of the floor to yellow. This rubber material is resistant to fire, and it won't let poisonous gas out when there's a fire.
* Making the normal seats to blue and made the priority seats to purple-fire resistant material. Similar to Seibu 30000 series, used the S-spring to the cushion material. Also made the curtains of the windows to a new one.
* Made the roof's air conditioning part to hard plastic from metal. Also, made advertisement place to the part they formerly had windows.
* Newly made door chime and changing the door engine and also made LED scroll to let passengers know information.
