The Sotetsu 12000 series (相鉄12000系) is an electric multiple unit (EMU) train type on order by the private railway operator Sagami Railway (Sotetsu) in Japan. A total of six ten-car sets were ordered for use on Sōtetsu Shin-Yokohama Line services.[2]

Technical specifications

The trains are built by J-TREC as part of their "Sustina S24 Series" design,[1] and use VVVF-IGBT technology.[4] They have stainless steel car bodies,[6] which carry the "Yokohama Navy Blue" corporate livery.[5]


In April 2018, Sotetsu announced the introduction of a new train type for Sōtetsu JR Link Line services.[7] The first set was delivered from J-TREC in December 2018.[8] Entry into revenue-earning service is scheduled for spring 2019. All six sets are scheduled to be introduced by the end of 2019.[4]
