The Chungbuk Line, which was built as a private railroad for the purpose of taking over the Chungbuk region of the Japanese occupation, is a railroad that connects Chungcheongbuk-do to Jecheon. During the Japanese occupation, it was connected to Chungju and was extended to Jecheon after liberation. The Chungbuk Line was more of an industrial railroad to transport underground resources in Gangwon-do than passengers. It was double-tracked in 1980, which had a major impact on the urban structure of Cheongju, Jeungpyeong, Eumseong, and Chungju, which are the main connecting areas of the Chungbuk Line, and recently, another change is expected as the Chungbuk Line high-speed project and the Regional Rail Development Plan have been established. However, the high-speed development of the Chungbuk Line and the wide-area railroad connecting to Cheongju Airport are focused on the development around the airport and the development of new cities in Cheongju, and small and medium-sized cities in Chungbuk, which are experiencing difficulties due to population decline, are somewhat excluded, so a railroad plan is needed to prevent the disappearance of regions in the future.
