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]

Formation edit

The ten-car trains are formed as follows, with six motored ("M") cars and four non-powered trailer ("T") cars, and car 10 at the Shinjuku (eastern) end.[2]

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 (京王ライナー)
  2. Keio Smart Liner (京王スマートライナー)
  3. Keio Prime Liner (京王プライムライナー)
  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]
