"Gyeongin Line Electric Railway Power Equipment Upgrade Project Begins Ahead of KTX Launch from Incheon"

The GTX Headquarters of the Korea Rail Network Authority announced on the 31st that it will promote the "Gyeongin Line Electric Railway Power Equipment Improvement Project" to secure power supply capacity before the opening of the KTX from Incheon and to upgrade aged substation equipment.

Electric railway substations are core facilities that convert extra-high voltage power supplied by Korea Electric Power Corporation (KEPCO) to a voltage suitable for train operation (AC 25kV).

Recently, there have been growing calls to secure substation capacity and upgrade aging equipment, considering the continuous expansion of metropolitan railway lines and the increased introduction of high-speed trains.

In response, the GTX Headquarters plans to invest a total of 68 billion won over four years and six months, from June of this year until November 2029, to complete upgrades at five locations, including Juan Electric Railway Substation and Bugae Sectioning Post, in order to ensure a stable power supply.

The Gyeongin Line Electric Railway Power Equipment Improvement Project aims to replace major substation equipment such as transformers and switchgear that have been in operation for 27 years, secure power supply capacity for the KTX from Incheon, and eliminate potential risk factors in advance to prevent equipment accidents.

Song Hyechun, Head of the GTX Headquarters at the Korea Rail Network Authority, stated, "We will continuously upgrade aging substation equipment to enhance the stability of metropolitan railway power supply and ensure the safety of train operations. During the construction period, we will prioritize on-site safety management to ensure the project is completed without any setbacks."
