Nine 8-car sets were built between 1982 and 1987, intended for use on all-stations "Local" services on the Seibu Ikebukuro Line. The trains combined 20 m long steel bodies with three pairs of sliding doors per side, based on the New 101 series design with similar underframes as the 2000 series trains. The trains were originally painted in the same livery applied to the 101 and 301 series trains, consisting of "lemon yellow" with a "warm grey" band around the windows, and unpainted stainless steel doors, but by 1999, the fleet was repainted in all-over yellow. The trains were air-conditioned from new.
Fleet
By 2014, the fleet consisted of two 8-car sets, based at Kotesashi and Minami-Iriso depots for use on Seibu Ikebukuro Line and Seibu Shinjuku Line workings respectively, and two 6-car sets based at Minami-Iriso. These sets were withdrawn from service by December 2014.

History
In 2010, sets 3005 and 3007 were reduced from eight to six cars, and the surplus cars scrapped. In December 2014, set 3009 was also reduced from eight to six cars. The last two remaining sets, eight-car sets 3009 and 3011, were withdrawn from service in December 2014.
Six-car set 3007 and six cars of former eight-car set 3009 were transferred to the Ohmi Railway in Shiga Prefecture following their withdrawal in November and December 2014, respectively.
