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.[4] Though the Seibu 2000 series were built from 1976 to 1993,[1] trains manufactured from 1988 were very different from previous models, and these are classified as the New 2000 series.

Fleet

[edit]

As of 12 December 2022, the fleet consists of 290 vehicles formed as two-car, four-car, six-car, and eight-car sets, and is based at Kotesashi, Musashigaoka, Minami-Iriso, Tamagawa-Josui depots for use on the Seibu Shinjuku Line and Seibu Ikebukuro Line.[5]

Interior

[edit]

Seating consists of longitudinal bench seating throughout. Priority seats are provided at the end of each car.[5]

History

[edit]

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.[4]

The last early-model 2000 series eight-car set, 2007, was withdrawn in April 2022.[6] Train set 2055 (a first generation six-car set) was manufactured in January 1989 and was set with a vehicle number of -10 in September 1991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.

Renewal

[edit]

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.[7] The first renewal was made to the train set 2047 (6 cars) which were renewed from December 2007 to March 2008. The renewal contents include:

Exterior

[edit]
  • Changing the pantographs to single-arm type.
  • Replacing the original destination displays with full-color LED displays.[Note 1]
  • Adding a number plate at the cab front to indicate the set number. (example: 2077)
  • On the side of the train, the part that shows the number of the train set was changed to a plate and windows on the door pockets were removed.
  • To stop passengers from falling onto the train tracks, in some of the train sets, they placed a speaker to warn passengers.
  • Exchanging the horn.
  • Train with added number plate at the cab front

Interior

[edit]
  • Changing the floor to grey rubber and in the areas close to the doors, the color of the floor became yellow.
  • Changing the seat moquetteto blue for regular seats and to a purple-fire resistant material for priority seats. Similar to Seibu 30000 series, the S-spring is used for the cushion material. The curtains of the windows were also replaced. Also, the spaces that had the extra windows removed became advertisement spaces.
  • Changing the material of the roof's air conditioning part to hard plastic from metal.
  • Adding a door chime, changing the door engine and including an LED passenger information display above the train doors.
  • Adding a wheelchair space and some other parts.
