The271 series (271系,271-kei) is anelectric multiple unit (EMU) train type operated byWest Japan Railway Company (JR West) onHaruka limited express services to and fromKansai International Airport.[1]
The trains inherit some of design elements of the 281 series currently used onHaruka services, such as its livery, the Haruka branding and the "square dot" logos.[1]
The trains are formed as three-car sets, and operate coupled with the existing281 series sets to form as nine-car train services.[2] The 271 series trains are formed as follows.[3]
| Car | End car | Intermediate car | End car |
|---|---|---|---|
| Designation | KuMoHa 271 | MoHa 270 | KuMoHa 270 |
The KuMoHa 271 car is fitted with one WPS28E single-arm pantograph.
The interior features a 2+2 seating arrangement with rotating and reclining seats, ACpower outlets on all seats, as well as dedicated luggage spaces. Multilingual passenger informations are provided on displays above the doors.[2]
On 21 June 2019 JR West announced the introduction of new 271 series trains onHaruka limited express services.[4] The order for 18 cars was worth 6 billionyen. The first train was unveiled at theKinki Sharyo head office on 10 July 2019.[2] The trains entered revenue service on 14 March 2020,[5] but due to the outbreak of theCOVID-19 pandemic and the subsequent drop of air travelers, JR West decided to postpone lengthening theHaruka trains to nine cars.[citation needed]
Currently, all Haruka trains are still formed in six car sets, with nine-car services intended to resume when air travel goes back to normal.[6] The sets re-entered service on 13 March 2021 with the introduction of that year's revised timetable when variousHaruka sets resumed 9-car operation.[citation needed]
