The was an electric multiple unit (EMU) train type operated by the private railway operator Seibu Railway on commuter services in the Tokyo area of Japan from 1982 until 2014.[1]
Nine 8-car sets (72 vehicles) were built between 1982 and 1987, intended for use on all-stations "Local" services on the Seibu Ikebukuro Line.[1] 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.[1] 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.[1] The trains were air-conditioned from new.[1]
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Line and Seibu Shinjuku Line workings respectively, and two 6-car sets based at Minami-Iriso.[2] These sets were withdrawn from service by December 2014.[3]
The eight-car sets were formed as shown below with six motored ("M") cars and two non-powered trailer ("T") cars.[2]

Seating consisted of longitudinal bench seating throughout. Priority seats were provided at the end of each car.[2]
In 2010, sets 3005 and 3007 were reduced from eight to six cars, and the surplus cars scrapped.[4] In December 2014, set 3009 was also reduced from eight to six cars.[5]
The last two remaining sets, eight-car sets 3009 and 3011, were withdrawn from service in December 2014.[3]
Ikebukuro Line set 3011 was repainted in a Galaxy Express 999 livery from May 2009, and set 3015 was repainted in a Saitama Seibu Lions baseball team livery from July 2010 and branded "L-train".[1]
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.[3]
