The Tobu 8000 series (東武8000系 Tōbu 8000-kei?) is a commuter electric multiple unit (EMU) train type operated by the private railway operator Tobu Railway in Japan since 1963. A total of 712 vehicles were built between 1963 and 1983, making this the most numerous EMU type operated by any private railway operator in Japan.[2]
Operations
Isesaki Line
The Isesaki Line fleet consists of 2-, 4-, and 6-car trainsets based at Kasukabe, Tatebayashi, and Shin-Tochigi depots. A fleet of 3-car 800 and 850 series trains converted from 8000 series units is also based at Tatebayashi Depot.
Kameido Line
The Kameido Line uses 2-car trainsets modified for driver-only operation.

History
Production
The first 8000 series appeared in November 1963 as 4-car sets. These were joined from December 1964 by 2-car sets (formed MoHa8500 + KuHa8600). Between 1971 and 1972, 14 pairs of additional intermediate cars (SaHa8700 + MoHa8800) were built and inserted into 4-car sets 8101 to 8114 to lengthen them to six cars. 8000 series trains built up to this point were not equipped with air-conditioning, but from June 1972, three 6-car air-conditioned sets (8156 to 8158) were delivered. The originally non-fitted sets were also modified with air-conditioning from October 1973 until 1983 at the Alna Kōki (now Alna Sharyō) factory in Osaka and Tsuha Sharyō factory in Nishiarai, Tokyo.
In May 1977, the first 8-car 8000 series set (8173) was delivered for use on the Tojo Line.
October 1979 saw the last two digits of individual car running numbers exceed 99, resulting in some cars receiving 5-digit (8xxxx) running numbers.
The last two sets built, 81120 and 8580, were delivered in 1983.[2]
The fleet changes between 1963, when the first sets were built, and 1983, when construction ended, are shown below.[3]

Refurbishment
Life-extension refurbishment began in 1986, and sets treated from 1987 received redesigned cab ends based on the 6050 series design. Sets refurbished from 1997 onward received HID headlights and LED external destination indicators, replacing the original roller blind type.
2001 saw the first appearance of 2-car sets modified for driver-only-operation. This included the addition of an automated bilingual (Japanese and English) passenger announcement system, internal LED passenger information displays, and external speakers.
Some of the remaining unrefurbished sets also received LED destination indicators.[2]
800 and 850 series conversion
From 2004, five 8-car sets were reformed to create pairs of 3-car 800 and 850 series driver-only-operation sets for use on Sano and Kiryū Line services. This conversion involved adding new cabs to former MoHa8300 and MoHa8200 intermediate cars.[2]
The new sets are formed as follows.[1]
800 series
- KuHa800-1
- MoHa800-2 (with two pantographs)
- MoHa800-3
850 series
- MoHa850-1 (with two pantographs)
- MoHa850-2
- KuHa850-3
Livery changes
When first built, the 8000 series sets were finished in a livery of "royal beige" and "international orange". From May 1974, sets were repainted into a simpler all-over livery of "sage cream". From 1985, sets were repainted into a new livery of "jasmine white" with dark and light blue bodyside stripes.
Commemorative liveries
One six-car set, 8108, was repainted into the original beige and orange livery between October 2004 and June 2005 to mark the 90th anniversary of the Tojo Line. This unit was subsequently returned to standard livery following overhaul in July 2005.[4]
In August 2012, six-car set 8111, preserved in running order by the Tobu Museum, was repainted into its original "royal beige" and "international orange" livery for a series of special event runs.[5]
In March 2014, to mark the 100th anniversary of the opening of the Tobu Tojo Line, four-car set 81111, based at Shinrinkoen Depot, was repainted into the all-over "sage cream" livery carried by sets from the 1970s.[6] This set operates on Tobu Tojo Line services between Ogawamachi and Yorii, and on Tobu Ogose Line services between Sakado and Ogose.[6]
In November 2014, four-car set 81107, based at Shinrinkoen Depot, was repainted into the original "royal beige" and "international orange" livery.[7]
From 28 November 2015, four-car set 8198, based at Shinrinkoen Depot, was repainted into the dark blue with yellow stripe livery carried by 54 series and 53 series EMUs used on Flying Tojo limited express services on the Tobu Tojo Line during the 1950s.[8]
From 23 March 2016, two-car set 8577, used on the Tobu Kameido Line and Tobu Daishi Line received the "international orange" and "medium yellow" livery carried by 7300 and 7800 series trains between 1958 and 1964.[9]
