Plans to construct a new substation for the Seoul Metropolitan Area Express Railway (GTX-C line) near residential apartments are encountering opposition from local residents. Concerns center around the proximity of the facility to homes. Authorities are now exploring options to utilize existing infrastructure to address these concerns and mitigate resident anxieties. A simulation will be conducted to assess the feasibility of repurposing current facilities instead of building a new substation. The project aims to improve transportation links in the greater capital region, but requires addressing community concerns for successful implementation. Further discussions and analysis will follow the simulation results to determine the optimal solution. The government seeks to balance infrastructure development with quality of life for residents.
