Background and overview
JR West had to deliver additional suburban dual voltage AC/DC electric multiple unit (EMU) trains for the start of electrified Nanao line between Tsubata and Nanao in 1991. JR West removed the AC electric equipments from 485 series EMU used on "Kita Kinki" intercity services which run in only the DC electrified lines to modify 113-800 series DC electric multiple unit trains into AC/DC dual voltage EMU trains with them over the period from 1990 until 1994 and classified modified 485 series vehicles into 183-800 series.
In addition, 485 series vehicles were additionally converted to 183-800 series to replace kiha181 series diesel multiple unit trains used on "Asashio" intercity services at the start of the electrified San-in line between Sonobe and Fukuchiyama in 1996.
Furthermore, 485 series vehicles which were used on "Shirasagi" intercity services and replaced with 683-2000 series were converted to 183-800 series to introduce dividing train services that "Maizuru" services were coupled with "Tamba" and "Hashidate" services between Kyoto and Ayabe in 2003.

Operations and withdrawal
183-800 series converted from 485 series were used on "Kitakinki" intercity services continuously. 183-800 series were additionally converted to displace kiha181 series diesel multiple unit used on "Asashio" intercity services at the start of electrified the San-in line between Sonobe and Fukuchiyama, and the Miyafuku line operated by Kitakinki Tango Railway between Fukuchiyama and Amano-Hashidate in 1996 and entered "Hashidate" services linking Kyoto and Amano-Hashidate, "Kinosaki" services linking Kyoto and Kinosaki, and "Tamba" services linking Kyoto and Fukuchiyama. They also entered "Monju" intercity services linking Shin-Osaka and Amano-Hashidate at the same time. Furthermore, they entered "Maizuru" intercity services linking Kyoto and Higashi-Maizuru at the start of electrified Maizuru line in 1999.
"Maizuru" intercity services started dividing train services coupled with "Tamba" and "Hashidate" services in 2003. However, train sets of 183-800 series used on dividing train services were displaced with 287 series in 2011. In addition, "Tamba" and "Monju" services were discontinued. Furthermore, remaining 183 series were displaced with 381 series, which had been used on "Kuroshio" intercity services and were completely scrapped in 2012. |
