The 10000 series is a commuter EMU operated by Tōbu Railway in Japan.

[edit] Variants

[edit] 10000 series

These were built to replace the remaining 7300 series trains on the Tōjō Main Line. The corrugated stainless steel body design was based on the prototype 9000 series set built in 1981, while the front end design was derived from the earlier 8000 series EMUs. The seat covers were initially brown ("Colorado orange"), but later changed to the standard light green colour used on sets built from 1986.

Sets are configured as 2-, 4-, 6-, 8-, and 10-car sets. The four 10-car sets (11003 to 11006) used on the Tōjō Line were formed in 1989 by adding two newly-built intermediate cars to 8-car sets 11803 to 11806.

Two 2-car sets (11201 and 11202) were transferred to the Tōjō Line in May 2008 to augment the two remaining 8-car sets following the decision to run only 10-car formations on the Tōjō Line from the start of the June 2008 timetable.

Total number of vehicles built: 118

[edit] 10030 series

10030 series 10-car formation headed by set 11441, September 2006

The 10030 subseries featured a new lightweight stainless steel body design, with a reduced number of bodyside corrugations and dull finish. A new bolsterless bogie was used. Internally, seat width was increased from 425 mm to 450 mm.

Two 10-car sets (11031 and 11032) were introduced in 1989 on the Tōjō Line, the first time fixed 10-car sets had been used on Tōbu overground trains.

Total number of vehicles built: 176

[edit] 10050 series

10050 series 6-car set 11658, October 2007

This sub-series was built from 1992 to replace non-air-conditioned 3000 series trains. The design incorporated a number of further minor changes to the previous 10030 series design.

Total number of vehicles built: 188

[edit] 10080 series

Identical in outward appearance to other 10030 series sets, one 4-car set (11480) was built in 1988 to test VVVF control equipment, which was subsequently used on the 100 series Spacia EMUs and later commuter EMU types.

Car 11480 of this set was experimentally repainted at Kasukabe depot for evaluation with blue/white/light blue stripes to match the colour scheme applied to the 8000 series sets, but this colour scheme was ultimately not used.
