History and Development
Construction of the Ilsan Line began on March 15, 1991, conceived as an extension of Seoul Metro Line 3. Although the project faced a minor setback in November 1995 when a test-run collision delayed the opening by two months, the line officially commenced direct operations with Seoul Subway Line 3 on January 30, 1996.
The line's administrative history was marked by a jurisdictional dispute. Following its completion, the Korean National Railroad sought to transfer ownership to the Seoul Metropolitan Government to avoid redundant management and workforce costs. However, the Seoul Metropolitan Government declined the request, citing that the line was located within Gyeonggi Province and expressing concerns over the resulting increase in expenditure. Consequently, the line remained under the jurisdiction of the Korean National Railroad, which later became Korail.
Over the years, the line has evolved to meet growing demand. A significant addition occurred on December 27, 2014, with the opening of Wonheung Station. The line has also weathered challenges, including a total suspension of operations on July 12, 2006, after heavy rains caused flooding in the underground sections.
Technical Specifications and Rolling Stock
The Ilsan Line utilizes a double-track system with a standard gauge of 1,435 mm. Power is supplied via 1,500 V DC overhead lines. To maintain high service standards, Korail manages its fleet through the Jichuk Depot, located conveniently near Jichuk Station.
The rolling stock has undergone several generations of updates. The line launched with 18 first-generation Korail 3000 series trainsets manufactured by Hyundai Precision & Industries between 1995 and 1997. To modernize the fleet, Korail is replacing these original trains with eight second-generation 3000 series sets from Hyundai Rotem and eight third-generation sets from Woojin Industrial Systems.
