Keio 7000 series

The Keio 7000 series is a Japanese city commuter electric multiple unit operated by the Keio Corporation since March 1984.
==History==
The 7000 series sets were Keio's first all-stainless steel trains. These were originally introduced for use on Express services to replace the 6000 series sets used on those services, but when these were introduced the 6000 series sets had mainly been moved to local trains. From 1984 to 1996 a total of 190 cars were produced. While originally manufactured for use on local trains the sets have since been used on all manner of services, from limited express to local, with the 2001 timetable revision. From 2003 to 2012 the sets were refurbished.
==Design==
The 7000 series cars feature a flat front with rectangular headlight casings; the sets also feature unpainted stainless steel bodies. The Keio corporate livery of pink and navy blue is seen on the sets; in the past the sets featured a red band around the length of the cars.
==Specifications==
Construction of the cars is of stainless steel. The sets are based on the Keio 6000 series cars; despite their differing appearance the sets share many mechanicals and feature nearly the same dimensions. The sets were originally equipped with field chopper controlled traction systems, although they have since been converted to use Hitachi IGBT variable frequency drive traction systems which produce a a wailing noise which steps up in pitch.
