The Keio 5000 series (京王けいおう電鉄でんてつ5000系けい) is an electric multiple unit (EMU) commuter train type operated by the private railway operator Keio Corporation in the Tokyo area of Japan since 29 September 2017. A total of six ten-car trainsets were built by J-TREC.[3] The trains feature rotating seats that can be arranged longitudinally for daytime services and in forward-facing transverse pairs for reserved-seat Keio Liner commuter services in the evenings which started on 22 February 2018.[3]

Design[edit]

Designed by Kazuhiko Saito and Taro Shiono, the Keio 5000 series is designed to be used in a broad range of scenarios by pursuing high degrees of ride quality.[1] The interior features motifs inspired by the trees of Mount Takao.[1] The train type was a recipient of the Good Design Award in 2017.[1]

History[edit]

Details of the new trains were officially announced in March 2016.[5] Between April and May 2017, Keio held a public poll to choose the brand name for the new reserved-seat services starting in spring 2018.[3] The name Keio Liner was announced on 24 January 2018, chosen from the following five candidates.[6]

  1. Keio Liner (京王けいおうライナー)
  2. Keio Smart Liner (京王けいおうスマートライナー)
  3. Keio Prime Liner (京王けいおうプライムライナー)
  4. Luxpress
  5. Westar

The fleet of five ten-car 5000 series trainsets was built by Japan Transport Engineering Company ("J-TREC") at a total cost of approximately JPY10 billion.[4][5]

The first trainset was delivered to Wakabadai Depot from the J-TREC factory in Yokohama in late June 2017,[7] and unveiled to the media on 19 July 2017.[8] It entered revenue service on 29 September 2017.[9] The fifth set was in service by January 2018.[10]

Reserved-seat Keio Liner services from Shinjuku Station commenced on 22 February 2018.[11] Inbound Keio Liner trains to Shinjuku will begin on 22 February 2019.[12][needs update]

The order of a sixth set was announced in April 2019.[13] The set was delivered in December 2019.[14]

Future plans[edit]

Keio plans to upgrade the seats on the 5000 series to include a reclining function. The program aims to begin revenue operation later in 2022.[15]

The updated seating was installed on a new 7th set. This new set, 5737, debuted on 24 December 2022.[16]

On 10 May 2024, Keio announced that as part of its fiscal 2024 capital investment plan, two more 5000 series sets are scheduled to be delivered to boost the frequency of Keio Liner services.[17]
