Twilight Express Mizukaze

The 87 series (87系), branded Twilight Express Mizukaze (TWILIGHT EXPRESS 瑞風), is a luxury hybrid diesel multiple unit (DMU) sleeping-car excursion train operated by West Japan Railway Company (JR West) in Japan since 17 June 2017. With a capacity of 34 passengers, the train is used on excursions in the Keihanshin, Sanin, and Sanyo regions of western Japan.

Design
The train was built jointly by Kawasaki Heavy Industries and Kinki Sharyo.

Propulsion
The train is a ten-car self-propelled hybrid diesel multiple unit (DMU) train combining a diesel generator and battery storage power, allowing it to operate on the non-electrified Sanin Main Line.

Styling
The train styling was overseen by industrial designer Tetsuo Fukuda (福田 哲夫) and architect and interior designer Kazuya Ura (浦 一也).

Logo
The train's logo design combines a stylized "M" with the angels used in the logo of JR West's Twilight Express sleeping car train, which operated from 1989 until March 2015.

Train formation
The ten-coach train consists of six sleeping cars, a lounge car, a dining car, and observation cars at either end of the train with open balconies. Five of the sleeping cars have three private suite rooms, while one car has a single luxury suite occupying the entire coach and featuring a bathtub and private balcony.
