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]
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 123-6) are operated by JR-West on the Ube Line, Onoda Line, and Sanyo Main Line.[3]
This car was converted from former baggage car KuMoNi 143-1 at Nagano Works in October 1986.[1] It was re-liveried in March 1990 following conversion to wanman driver only operation.[1]
These three cars were converted in February 1987 at Hiroshima Works from former baggage cars KuMoNi 143-2, 143-3 and 143-6, respectively, originally for use on the Kabe Line.[1] The two original pantographs were replaced with one PS16J lozenge-type pantograph at the No. 1 end.[1]
These two cars were converted in April 1987 at Suita Works from former baggage cars KuMoNi 143-7 and 143-8, respectively, originally for use on Hanwa Line branch services.[1] The original pantographs at the No. 1 end were removed on conversion.[1]
These cars were converted from former post and baggage cars KuMoYuNi 147-1 to 147-5 in January 1987.[1]
These two cars were converted in March 1988 by JR Central at Hamamatsu Works from former tractor cars KuMoYa 143-601 and 143-602, respectively, for use on the Minobu Line.[1] These cars had gangway doors at the ends, three sliding doors per side, and two pantographs.[1] Inverter-controlled air-conditioning was added in December 1988.[1]
These cars were modified in June 1989 at Hamamatsu Works by JR Central from earlier KuMoHa 123-40 series cars, with the addition of inverter-controlled air-conditioning.[1]
These cars were modified by JR Central from earlier KuMoHa 123-5045 , for use on wanman driver only operation services on the Minobu Line. Gangway doors were also added on conversion.[1]
The last remaining 123 series car operated by JR East was withdrawn from the start of the revised timetable on 15 March 2013, with operations replaced by E127 series two-car EMUs.[4]
