The Sōtetsu 7000 series (相鉄7000系?) and Sōtetsu New 7000 series (相鉄新7000系?) are DC commuter electric multiple unit train types operated by Sagami Railway (Sotetsu) in Kanagawa Prefecture, Japan. They were designed to operate as 8-car or 10-car sets, but the New 7000 series operates only as 10-car sets.

7000 series[edit]

7000 series (right) and 5000 series EMUs

History[edit]

Built from 1975 by Hitachi in Yamaguchi Prefecture. A total of 80 cars were built.

Body[edit]

They had lightweight aluminum bodies, like the 5000 series and 2100 series EMUs.

Initially, 7700 (Tc), 7500 (Tc) and 7100 (M) cars were built. From 1983, 7000 (Mc) and 7600(T) cars were added to form 10-car and 8-car sets.

Interior design[edit]

This series has power windows at all windows.[citation needed]

Operation[edit]

Eight-car set trains are used on "local" all-stations services. Ten-car sets are used on "rapid" and "express" services.

From 2006, 7000 series sets began to be replaced by Sōtetsu 10000 and Sōtetsu 11000 series EMUs.

New 7000 series[edit]

History[edit]

From 1986, the front-end design of the 7000 series was changed. To differentiate between the original 7000-series cars, those with the new design are referred to as the new 7000 series (新7000系?). Some EMUs in this series use variable-frequency drive motors.

Current usage[edit]

A total of 60 cars have been built, and all are in use.

Refurbishment[edit]

New 7000 series, in revised livery.

The 7000 series and New 7000 series have been refurbished, since 2008, with the following changes.

Safety systems[edit]

The company plans to build a new line linking to East Japan Railway Company (JR East), and so Sotetsu began to change the original safety system to the standard JR type.
