Historical Development
The origins of the Honam Line date back to 1896, when a French company first proposed a railway connecting Seoul to Mokpo. However, the project's trajectory changed significantly following the Russo-Japanese War. In May 1904, Imperial Japan secured control over Korean railways, leading to the seizure of land in the fertile Honam plain to facilitate construction.
Construction Timeline
Construction officially commenced in 1910, with the line opening in several stages:
- 1911: The first 39.9 km section between Daejeon and Yeonsan opened in July, followed by an extension to Ganggyeong in November.
- 1912: The line reached Iri (now Iksan) in March, Gimje in October, and Jeongeup in December.
- 1913: Construction moved from the southern end, opening the Mokpo to Hakgyo section in May, extending to Naju in July, and reaching Songjeong-ri (now Gwangju·Songjeong) in October.
- 1914: The entire line was completed on January 11 when it finally connected to Jeongeup.
Modern Upgrades and Infrastructure
To meet the demands of modern transit, the Honam Line has undergone extensive duplication (adding a second track) and electrification. The process of double-tracking began in 1968 and progressed through several phases:
- 1978: The section from Daejeonjochajang to Iksan via Seodaejeon was completed.
- 1988: Double-track work south of Iksan reached Gwangju (Songjeong-ri).
- 2004: The final single-track section between Songjeong and Mokpo was completed, and the entire line was electrified to support the launch of Korea Train Express (KTX) services.
Speeding-up the Network
In a recent effort to enhance high-speed connectivity, the section from GwangjuSongjeong to Gomagwon was upgraded to support maximum speeds of 230 km/h. This 25.9 km project was completed in June 2020, specifically to accommodate KTX and SRT services.
Major Stations and Junctions
The Honam Line features several strategic stations that serve as vital transit points:
- Daejeon: A major junction connecting with the Gyeongbu Line toward Seoul and Busan.
- Seodaejeon: The primary passenger station for Honam Line services in the Daejeon area.
- Iksan (formerly Iri): A critical hub serving as the terminus for both the Jeolla and Janghang Lines.
- GwangjuSongjeong: The primary station for Gwangju, acting as a junction for the Gyeongjeon Line and a gateway for trains heading to Mokpo.
- Naju: A significant regional station in Naju.
- Mokpo: The southern terminus located at a major seaport.
Service Overview and Travel Times
The line accommodates a diverse range of traffic, including freight and various passenger classes. Travelers can choose between high-speed KTX, intercity ITX-Saemaeul/MAUM, and the Mugunghwa-ho.
As of October 2024, travel times vary significantly by service type.
