Since the third inter-Korean summit, the inter-Korean summit in Pyongyang and the U.S.-North Korea summit in Singapore and Hanoi, denuclearization negotiations are under way that will determine the fate of the Korean Peninsula. However, the negotiations are stalled and some skepticism is expected due to the conflicting U.S.-North Korea stance over the terms of denuclearization. The reason why it is difficult to realize the complete denuclearization of North Korea is that there are a variety of variables such as the traditional security dilemma in Northeast Asia, the hegemonic competition between the U.S. and China, and the formation of a new cold-war system. At a turning point when three inter-Korean summits and three U.S.-North Korea summits were held in the wake of the 2018 PyeongChang Winter Olympics, North Korea's complete denuclearization has become a must-do historical task for Northeast Asia and world peace beyond the Korean Peninsula. In this sense, the inter-Korean summit in Pyongyang is seen as a historic occasion for presenting a new milestone for the denuclearization of North Korea and the development of inter-Korean relations through the 9.19 Pyongyang Joint Declaration and the Military Agreement. Meanwhile, Constructivism, which has become the main paradigm of international political theory, presents the view that ideological variables such as ideology, history and culture define material factors, identity and interests of state actors, and that the structure of international relations can be changed through interaction. In this study, the historical meaning of the 9.19 Pyongyang Declaration, which is now past its first anniversary, was considered from a constructivist perspective. To this end, the development process of constructivism theory and analysis model and the development process of inter-Korean relations were briefly reviewed, and the military implications of the 9.19 Military Agreement were presented.

The two Koreas agreed to pursue rail and road connections on September 19, 2018 in the Pyongyang Joint Declaration. In December 2018, they launched a joint investigation for the North Korean railway modernization project. The survey confirmed that the track condition is seriously aging so that it is impossible to operate, and the railway network is well connected to major cities. Therefore, it was reasonable to modernize the aging track of the existing railway network rather than construct a new railway network. This paper proposed the railway communication policy for the improvement of railway lines and the construction of the railway wireless network by analyzing the status of roadbeds and tracks in order to enhance interoperability for the inter-Korean railway connection and safety for preventing the railway accidents.
