History
A total of 130 cars were built between 1990 and 2000 by Hitachi in Yamaguchi Prefecture. They replaced many of the aging 6000 series and new 6000 series sets.
Set 8707 was involved in a collision with a track maintenance vehicle in March 2004, at Shonandai Station, and was scrapped in 2006. The set was replaced by a newer Sotetsu 10000 series set.
Refurbishment
Body
- The air conditioners were changed to new freon-based type.
- Some diamond-shaped pantographs were changed to single-arm.
- From 2008, the livery was changed to a new livery based on that used on the Sotetsu 10000 series.
Interior design
- Some early formations do not have wheelchair space, so it was added in the 8700 and 8500 cars.
- The bench seats were replaced with sculpted longitudinal seats and the sat covers were changed from orange to purple.
- Both ends of the seat were attached to white partition board and a curved pole.
Safety system
- ATS was changed from original type to the same type as the East Japan Railway Company.
- A new safety system was established. If no control in one minute, then the emergency brake engages and the train stops. This system is named by Japan "EB".
