The Honam High Speed Railway (Honam HSR) is a high-speed railway under-construction between Osong (on the existing Gyeongbu High Speed Railway) and Mokpo in South Korea. The line will become part of Korail's Korea Train Express (KTX) system, accelerating Seoul-Mokpo and Seoul-Gwangju KTX high-speed services which presently use the existing conventional Honam Line.
Origins of the project
The most progressed plans for a second high-speed line were for the Honam High Speed Railway, a connection from Seoul to Mokpo in southwest Korea, accelerating the service on the existing route that was eventually established in KTX's first phase.
The first feasibility study in 2003 came to the conclusion that the construction of a full line is not justified by demand, and proposed a two-stage construction. The first stage, to be realised by 2015, would involve a connection from a second Seoul terminus in the southeast part of the city to the Gyeongbu HSR, and a branch from the Gyeongbu HSR to Iksan, paralleling the existing Honam Line. The second phase, to be realised by 2020, would include the separate tracks on the section paralleling the Gyeongbu Line, and the extension from Iksan to Gwangju and Mokpo, paralleling the existing Honam Line. The cost of the entire project was estimated at 10,378.6 billion won.
On January 14, 2005, Prime Minister Lee Hae Chan met local representatives in Gwangju, who requested an early implementation of the project. Lee pointed to the failure of the first phase of the KTX in meeting ridership forecasts during its first months, expressed skepticism regarding the profitability of the Honam HSR, and described it as a long-term project. However, in December the same year, in the light of low approval in the affected provinces, the government reversed its stance and agreed to complete the project to Gwangju by 2015.
In plans made official in August 2006 in spite of a benefit-cost ratio below 1, the budget for the 182.75 km first stage (from the new Osong Station on the Gyeongbu HSR to Gwangju) was set at 8,569.5 billion won. The second stage, the 48.74 km remaining to Mokpo, was to be finished by 2017 with a budget of 2,002.2 billion won. The altogether 230.99 km, 10,571.7 billion won project would enable Seoul-Mokpo travel times of 1 hour 46 minutes. Ahead of the 2007 Presidential elections, eventual winner Lee Myung-bak promised to accelerate the project by 3 years (with the first section finished by 2012). While this date was deemed unrealistic by the responsible ministry, a one-year acceleration (first phase in 2014) was announced in January 2009. The Osong-Iksan section of the first phase is also intended for use as high-speed test track for rolling stock development, to be fitted with special catenary and instrumented track.
The project is financed to 50% by direct government funds and 50% loans.
By December 2009, construction began on three sub-sections of the 182 km line from Osong to Gwangju, which shall enable Seoul-Gwangju travel times of 1 hour 30 minutes. The ground-breaking ceremony was held at Gwangju·Songjeong Station in the attendance of President Lee Myung-bak on December 4, 2009, when total project costs were estimated at 11.3 trillion won (US$9.8 billion). As of September 2010, progress was 9.6% of the project budget then estimated at 10,490.1 billion won for the first phase, while the estimate for the entire line stood at 12,101.7 billion won.
The entire line from Osong to Mokpo will include a total of 111.7 km of viaducts (48.35%) and 49.12 km of tunnels (21.26%).
Trains will stop at six stations along the line:
|Osong Station||0.00 km||121.78 km||0h46m||-|
|Namgongju Station||43.82 km||165.60 km||0h59m||-|
|Iksan Station||89.52 km||211.30 km||1h13m||1h09m|
|Jeongeup Station||131.75 km||253.53 km||1h25m||-|
|Gwangju·Songjeong Station||182.25 km||304.03 km||1h41m||1h33m|
|Mokpo Station||230.99 km||352.77 km||1h55m||1h46m|
