Tokyu 6000 series (1960)

The Tokyu 6000 series is a Japanese city commuter electric multiple unit operated by the Tokyu Corporation from April 1960 to October 1989.
==History==
The 6000 series sets were designed as a high-performance train for use on the Tōyoko Line using technology originally introduced on the 5000 and 5200 series sets, such as stainless steel bodies and cars that are easy to mass produce. An initial order of two four-car sets were produced in 1960, classified the A-type and B-type and numbered 6002 and 6202 respectively, to evaluate their performance; both sets featured the same bodies but different underbody mechanicals. After tests the A-type set was deemed superior, and as such three more four-car sets, named the C-type sets, were manufactured with increased power and using the traction motors of the A-type sets. The sets were also used for various tests, with 6002 and 6202 most notably receiving prototype GTO variable frequency drive traction systems; those sets were retired in 1986. Over their service lives the sets changed formations a few times before being standardized in 4-car formations and retired in 1989.
After their retirements on the Tokyu network two C-type sets were moved to the Konan Railway while one C-type set was moved to Hitachi for testing as a generic commuter train at their headquarters before it was later scrapped. The A and B-type sets were not repurchased, with the A-type set scrapped. One complete set, 6202, survives, although it is not connected; as of 2004, the four cars of the set were being used as storage space in various places in Ibaraki. A number of cars owned by the Konan Railway also survive.
A train with the same designation was introduced in 2008; other than both sharing a name both trains are unrelated. As a result, this train has often been referred to as the "old 6000 series".
==Design==
The 6000 series cars use a contemporary design featuring a flat front and a top-mounted headlight.
==Specifications==
Construction of the cars is of stainless steel. The trains used resistor-controlled traction systems. The traction motors on the trains produced a distinctive wailing noise, which led to the trains being colloquially known as the "siren train".
