The GTX Headquarters of the Korea Railroad Corporation has officially begun efforts to establish a stable power supply system in preparation for future railway demand.
On September 9, the GTX Headquarters announced plans to upgrade aging rail power supply equipment to support stable operations on the Gyeongin Line and respond to increasing railway traffic demand.
Rail power supply equipment is responsible for supplying electricity necessary for train operations and regulating voltage to ensure stable power delivery.
The power supply equipment at the Juan substation has been in operation for about 30 years, and concerns have been raised about its aging and performance degradation potentially disrupting train services, highlighting the need for upgrades.
In response, last October, the GTX Headquarters initiated the "Gyeongin Line Rail Power Supply Equipment Upgrade Project" to secure power capacity in anticipation of the opening of the KTX service from Incheon. According to the announced plan, a total of 68 billion won will be invested to complete upgrades at five locations by November 2029.
On this day, the corporation stated that it will comprehensively upgrade the existing Gyeongin Line power supply equipment to enhance power supply capacity and equipment reliability. Measures will be taken to ensure stable power supply for currently operating lines, including the Gyeongin Line and the upcoming Incheon KTX and Wolgot-Pangyo lines.
The capacity of the surrounding transformers will be increased by 50%, from the current 60 MVA to 90 MVA, expanding power supply capabilities. While four existing power supply facilities, including the Juan substation, will be dismantled, four new facilities, including the Incheon substation, will be established.
Existing insulating gas will be replaced with eco-friendly dry air. The introduction of a carbon-reducing facility, the "170kV eco-friendly gas-insulated switchgear," will be implemented for the first time, incorporating feedback from on-site operators.
Song Hye-chun, head of the GTX Headquarters, stated, "Through this upgrade project, we will proactively establish a stable power supply system to meet future railway demand and create a safe train operation environment through seamless project execution."
