The Seibu 2000 series (西武2000系) is an electric multiple unit (EMU) train type operated by the private railway operator Seibu Railway on commuter services in the Tokyo area of Japan since 1977.[1]
Design
The 2000 series trains were introduced on all-station stopping 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.[1] 130 vehicles were built between 1977 and 1988, including some replacements for cars damaged in accidents, and this first batch was followed by a batch of 304 vehicles classified "New 2000 series" built between 1988 and 1992.[1]
