## Technical specifications

The car bodies are made out of stainless steel.[2] The train is equipped with a [storage battery](/source/Storage_battery), which can be charged with the regenerated power from braking. JR Kyushu reports that the hybrid system consumes 20% less fuel than the [diesel-hydraulic](/source/Diesel_multiple_unit#Diesel–hydraulic) [KiHa 66 and 67](https://en.wikipedia.org/w/index.php?title=KiHa_66_series&action=edit&redlink=1) trains, which were envisaged to be replaced by the YC1 series.[2][4]

## History

The first set, a 2-car set, was delivered in June 2018,[5] and is based at Sasebo depot. The set was used in a test run on the [Nagasaki Main Line](/source/Nagasaki_Main_Line) and [Sasebo Line](/source/Sasebo_Line) in March 2019.[6] Revenue service began on 14 March 2020.[7] Throughout 2020, twenty-four YC1 series cars were delivered from [Kawasaki Heavy Industries](/source/Kawasaki_Heavy_Industries_Rolling_Stock_Company)' Hyogo plant.[8][9][10][11]

Since 23 September 2022, a majority of Nagasaki Main Line local and rapid services have been operated using YC1 series trains.[1]
