Tokyo Metro 9000 series
Encyclopedia
The is an electric multiple unit
type which operates on the Tokyo Metro Namboku Line
in Tokyo, Japan.
in 1990 (formed of cars 9101-9201-9301-9801) for testing on the Chiyoda Line prior to the opening of the Namboku Line in 1991.
The original 4-car sets were reformed as 6-car sets coinciding with the opening of the extension of the line from Yotsuya
to Komagome
on 26 March 1996. This was achieved by renumbering the centre cars (9200 and 9300) of sets 02, 04, 06, and 08 as 9600 and 9700 cars which were inserted into sets 01, 03, 05, and 07. New-build (2nd batch) intermediate cars (9200-9300-9600-9700) were then inserted into sets 02, 04, 06, and 08. The resulting minor differences led to odd-numbered sets 01 to 07 being classified as "A sets", and even-numbered sets 02 to 08 becoming "B sets".
between 1995 and 1996, coinciding with the opening of the extension of the line from Yotsuya
to Komagome
in March 1996. Floor height was reduced by 5 mm compared with the 1st batch sets from 1,155 mm to 1,150 mm. Seat width was increased from 440 mm to 450 mm.
to coincide with the opening of the extension of the line from Yotsuya
to Tameike-Sannō
on 20 September 1997. Externally and internally, these were identical to the 2nd-batch trains.
between 1999 and 2000 ahead of the opening of the extension of the line from Tameike-Sannō
to Meguro
on 26 September 2000. The motored cars 3 (9300) and 4 (9600) in these sets have only one powered bogie, as opposed to two on earlier sets. Friction stir welding
was used in the construction of these sets to produce a more attractive exterior finish.
Two new 6-car sets (22 and 23) entered service from 22 May 2009. These include a number of design improvements over earlier sets, including a redesigned front end, single-arm pantographs, and improved air-conditioning. The number of motored cars is reduced from four to three per 6-car set, with car 3 (trailer car) numbered in the 9400 series. Car 4 (9600) has both bogies powered. Seat width is increased 10 mm to 460 mm, and floor height is reduced 10 mm to 1,140 mm.
