Keio 9000 series

The Keio 9000 series is a Japanese city commuter electric multiple unit operated by the Keio Corporation since January 2001.
==History==
The 9000 series sets were introduced as a new and modern train for the Keio network, replacing the 6000 series sets. The 9000 series cars are notably barrier free, with cheap maintenance and running costs and are more environmentally friendly. From 2000 to 2009 a total of 264 cars were produced, with the sets entering service on 24 January 2001. Later 10-car sets, numbered in the 9030 series, were built to through run to the Toei Shinjuku Line.
==Design==
The 9000 series cars feature a flat front with bottom-mounted horizontal rectangular headlight casings; the sets also feature unpainted stainless steel bodies, but do not feature the typical "lines" typical of stainless steel cars. 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 equipped with Hitachi IGBT variable frequency drive traction systems which produce a loud wailing noise.
