The 123 series (123系 Hyaku-nijūsan-kei) is a single-car electric multiple unit (EMU) train type introduced in 1986 by Japanese National Railways (JNR), and later operated by East Japan Railway Company (JR East), Central Japan Railway Company (JR Central), and West Japan Railway Company (JR-West).[1]

Overview

The 123 series was created in 1986 from former KuMoNi 143 baggage cars which had become surplus to requirements. Some units were also converted from KuMoYuNi 147 postal cars (123-40 series, later 123-5000 series), and from KuMoYa 143 tractor cars (123-600 series).[1][2]

Operations

As of 1 April 2012, one 123 series car (KuMoHa 123-1) is operated by JR East, based at Matsumoto Depot for use on the Chuo Main Line and Shinonoi Line.[3] Five 123 series cars (KuMoHa 123-2 to 6) are operated by JR-West on the Ube Line, Onoda Line, and Sanyo Main Line.[3]
