A Honam Railway from Seoul to Mokpo was first proposed in 1896 by a French company. After the start of the Russo-Japanese War, in May 1904, Imperial Japan forced Korea to sign an agreement granting the Japanese military control over railways, including the right to seize land. Japan the seized much of the fertile Honam plain in advance of a planned Honam Line. The construction of the line started in 1910. The first between Daejeon and Yeonsan was opened in July 1911. The line was extended to Ganggyeong in November 1911, to Iri in March 1912, to Gimje in October 1912 and to Jeongeup in December 1912. Construction continued from the other end of the line, with the section from Mokpo to Hakgyo opened in May 1913; and extended to Naju in July 1913, to Songjeong-ri in October 1913, and finally to Jeongeup, completing the line on January 11, 1914.
Upgrade
The Honam Line was upgraded to an electrified and double-tracked line for higher speeds in stages. Double-tracking construction work started in 1968. Double-tracking of the last remaining single-track section, Songjeong–Mokpo, and the electrification of the whole line, including the Gwangju spur, was finished for the start of Korea Train Express services on April 1, 2004. The present line length from Daejeon to Mokpo is, the line distance from Seoul to Mokpo is.
Major Stations
Major stations and junctions along the line include:
The Honam Line is served by freight trains, as well as cross-country Mugunghwa-ho, intercity Saemaul-ho and high-speed KTX passenger trains. As of October 2010, minimum travel time from Yongsan Station in Seoul to Mokpo is a minimum 4 hours 42 minutes by Saemaul and a minimum 5 hours 2 minutes by Mugungwha. On the Honam Line itself, from Seodaejeon to Mokpo, travel time is a minimum 2 hours 51 minutes by Saemaul and a minimum 3 hours 5 minutes by Mugungwha.
Honam KTX
When Honam KTX services started on April 1, 2004, the shortest rail travel time between the capital and Mokpo was reduced from 4 hours 32 minutes to 2 hours 58 minutes. between Seoul and Gwangju, the time reduced from 3 hours 53 minutes to 2 hours 38 minutes. At the Seoul end, since the December 15, 2004, timetable change, most Honam KTX services don't terminate in Seoul Station, the terminus of the Gyeongbu KTX services, but in nearby Yongsan Station, from where the travel distance to Mokpo Station is 404.4 km. In addition, some services are extended beyond Yongsan, passing Seoul Station and continuing for 14.9 km along the Gyeongui Line to terminate at Haengsin Station, next to which KTX trains have a depot. The service uses the Gyeongbu HSR until Daejeon, and the upgraded Honam Line from there. The service calls at the following stations: The frequency of Honam HSR services was increased in steps from the initial 34 daily runs in 2004, and changes between a minimum 38 services a day on weekdays and a maximum 40 on weekends from the November 1, 2010 timetable.
Ridership
The predicted first-year average daily ridership of the Honam KTX Line was raised from 22,818 in a November 1999 estimate to 36,085 in the final August 2003 forecast. Actual first-year numbers were about a half of the original estimate, but rose significantly in the second and third year. In its first year of operation, the Honam KTX service also underperformed in seat occupation relative to the Gyeongbu KTX service. By 2005, KTX fares were selectively reduced for relations under-performing most, especially on the Honam Line: Following general ticket price increases and the separation of weekday and weekend fares, as of November 2010, the standard one-way Seoul to Mokpo ticket price stands at 40,500 won on weekdays and 43,300 won on weekends, but with significant reductions on newly introduced non-reserved seats. Another problem passenger surveys in the first months found was station access and the limited capacity of bus connections, leading to the frequent use of taxis.
Modal share
After its first year of operation, on relations with significant distances along the conventional Honam Line, the Honam KTX service gained market share mostly at the expense of conventional trains, while the total share of rail was stagnant on some relations. By 2008, between Yongsan and the cities mid-way along the Honam Line, rail's total modal share passed 50%. Strong gains at the expense of air transport and private cars were seen between Yongsan and Honam KTX service endpoints Mokpo and Gwangju, too.
Future improvements
Starting from April 2011, the new Jeolla KTX service will share tracks with the Honam KTX until Iksan, and diverge from there to reach Yeosu along the Jeolla Line. Korail also plans to run some through KTX services to Incheon International Airport on the AREX line from 2012. The planned travel time between Incheon International Airport and Gwangju is 3 hours. From 2014, the Honam KTX Line is to transfer to the future Honam High Speed Railway between Osong on the Gyeongbu HSR and Gwangju·Songjeong. By 2017, the service will transfer to the new line on the remaining section to Mokpo, too.
