Keio 8000 series

The Keio 8000 series is a Japanese city commuter electric multiple unit operated by the Keio Corporation since May 1992.
==History==
The 8000 series sets were introduced in preparation for the increase in transportation capacity with the opening of a new extension between Fuchū and Kitano. These were also Keio's first all-new trains since the 6000 series sets introduced in 1972. From 1992 to 1999 a total of 244 cars were produced, with the sets entering service on 11 May 1992. The sets have been refurbished since 2013.
One car, 8728, was involved in a landslide incident; it sustained heavy damage and was scrapped. 8564 was manufactured by Tokyu Car Corporation in 2009 and added to the set. As this car was inserted next to an ex-cab car, 8559, the set featured a blocked gangway; in 2014 modifications were taken to remove the cab from the car and open the gangway.
The removed cab from car 8559 is displayed at Keio Rail Land.
==Design==
The 8000 series cars feature a slightly raked front with bottom-mounted horizontal 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. Unlike all of Keio's other rolling stock the 8000 series sets operate on Keio lines only.
==Specifications==
Construction of the cars is of stainless steel. The sets were originally equipped with Hitachi GTO variable frequency drive traction systems which produce a loud wailing noise; some of the old GTO drives have been replaced with hybrid SiC MOSFETs which produce a hissing noise.
==Incidents==
24-year old Kyota Hattori carried out a knife and arson attack onboard set 8705 on 31 October 2021; he injured 17 people, one critically. Some of the attackers thought the attack was a Halloween stunt until Hattori was seen waving a long bloody knife. Hattori was arrested soon after the train made an emergency stop and was said to have been inspired by a similar attack carried out on an Odakyu Electric Railway train a few months prior. After a long series of legal proceedings Hattori was found guilty and sentenced to 23 years in prison.
