The Sotetsu 8000 series (相鉄8000系) is a DC electric multiple unit (EMU) train type operated by the private railway operator Sagami Railway (Sotetsu) in Kanagawa Prefecture, Japan, since 1990.[1]

Body

The trains use a lightweight aluminium body.

Interior design

Some cars have transverse seating.

Electrical equipment

The motor system is based on the New 7000 series.

This series adopted variable-frequency drive motors named "Hitachi HSV-03"; the motor power is 150 kW and installed as 4 motors per car. Power cars are two cars as one pair. The 8100 car establishes the VFD-controller, and the 8200 car establishes a compressor, etc.

The brake system was finished with Hitachi HSC and adopted brake by wire with regenerative brake.

Bogies are based on the New 7000 series, too. The name is "KH132B" (for power cars) and "KH135B" (for others).

Safety system

The safety system uses a dead man's switch and automatic train stop.

History

Set 8706 in original livery in October 2008
Set 8706 in original livery in October 2008

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. Set 8702 was withdrawn from service on 13 March 2020 for aging reasons and due to the introduction of newly built set 12106 and was scrapped in April of the same year.
