Light and Shadow of GTX Lines and Real Estate Polarization by Region... "Trust Confirmed Sections, but Exercise Caution with Long-term Outlook"

An analysis has been released regarding the operational status and future outlook of the Seoul–Gyeonggi Area Metropolitan Express Railway (GTX) lines, as well as the real estate market polarization in major provincial cities. According to a video by Dr. Kim Si-deok released on the 'Finance with Toad Tax Accountant' YouTube channel, GTX lines show significant differences in operational efficiency depending on the demand of each section and track-sharing issues.

Imbalance between GTX lines and construction delay issues... "Samseong Station transfer center requires a long-term perspective"

In the case of the GTX-A line, it was found that the usage environment of the northern section and the southern section are different. In the video, Dr. Kim explained, "The north has a dense dispatch interval and many users, but in the southern section, it is difficult to reduce the dispatch interval due to low demand and issues such as sharing tracks with the SRT." In fact, while the southern section shows a dispatch interval in the 20–30 minute range, the difference is large enough that the north operates at intervals as short as 6 minutes. Accordingly, concerns were raised that if the dispatch interval in the southern section widens, it could affect the dispatch interval of the northern section due to operational efficiency issues with existing lines like Line 4. However, options such as separating the lines near Suseo Station could be mentioned as alternatives.

Regarding the GTX-B and C lines, an analysis of the actual utility of the lines followed along with the construction progress. For GTX-B, while construction is underway for the entire section, it was pointed out that the purposes of the western section (private) and the eastern section (public) are different. In particular, since the eastern section focuses on resolving the bottleneck of existing trains, the analysis suggests that it remains to be seen how much effect the expansion of accessibility to Seoul Station, which residents in western areas such as Songdo, Incheon, are expecting, will achieve. However, the point where it meets the GTX-D line at Bucheon Stadium Station was cited as a section with noteworthy future value. In the case of GTX-C, questions were raised about whether it can secure the expected speed as the Gyeonggi Province section shares tracks with the existing Gyeongwon Line and Gwacheon Line. In particular, it was mentioned that the track-sharing issue in the Gyeonggi Province section could make it difficult to reduce dispatch intervals in the future or lead to situations where the number of trains for Line 1 (bound for Soyosan) or Line 4 (bound for Geumjeong and Ansan) must be reduced.

Regarding the recent issues of construction delays at Samseong Station and rebar-related problems, he diagnosed, "Just because Samseong Station construction is delayed does not mean you are in a situation where you must sell your house." Regarding the rebar omission issue, he expressed the view that it appeared to be an error in the construction process rather than malicious cost-cutting. Furthermore, pointing out that the scheduled opening of Samseong Station has been delayed from the original June to early 2027, he emphasized that the Yeongdong-daero Complex Development Project is a national project where large-scale redevelopment will proceed until 2040, going beyond a simple railway project, much like Shinagawa Station in Tokyo, Japan. Comparing it to how Shinagawa Station is undergoing large-scale construction including vehicle yards and buildings as a hub connecting Haneda Airport and Tokyo Station until 2040, he added, "Rather than short-term construction delays, it should be approached from a long-term perspective looking 40 years ahead."

"Politics and Railways are One Body"... GTX-D extension and reproduction of past railway plans

Regarding the possibility of the GTX-D line extension to Wonju, a view was presented that political variables may play a role. Dr. Kim suggested that "from a profitability standpoint, connecting to Wonju is difficult to accept, but railways are closely linked to politics," implying that routes can be decided according to the influence of politicians from a region or the logic of balanced regional development. In particular, although Wonju is already advertising apartment sales on the premise that GTX-D is coming, he offered a cautious outlook that its actual realization might be something that happens 30 years from now.

Additionally, it is an interesting point that some railway plans currently being promoted are inheriting past plans. The explanation is that the plan to extend Line 7 to Yangju Okjeong and Pocheon follows the flow of the 'Gyeongseong–Pocheon Railway' plan of the 1930s. The plan at that time was a concept to connect Gyeongseong through Pocheon to Gima in Gangwon Province and the Geumgangsan Electric Railway. Dr. Kim explained the phenomenon where past plans appear renewed in the modern era, saying, "Once a line is drawn, it holds power because it possesses geographical rationality and historical flow regardless of feasibility." In addition, analyses continued that the Southern Inland Railway (Geoje~Gimcheon) or the Dalbit Inland Railway (Daegu~Gwangju) also touch upon plans from the Japanese colonial period.

Cheongju real estate market's 'macro statistical trap'... "Regional separation phenomenon based on occupation is distinct"

In the case of provincial cities, a 'regional polarization' phenomenon is observed that is difficult to judge by statistical figures alone. Using the case of Cheongju City, the presenter analyzed, "Cheongju is a city with a macro statistical trap." The market trends in the northwestern region, where semiconductor-related companies such as SK hynix are located, are completely different from the existing downtown and the southeastern region where new development is underway. While demand is concentrated in the northwestern region due to the influx of semiconductor-related workers, it was explained that the market moves separately within the region according to capital and occupation, such as the issue of oversupply due to approximately 20,000 households of move-in volume until 2028 in other areas.

This phenomenon is in line with the case of Osong Station in Sejong City. Cheongju City attempted to change the name of Osong Station to 'Cheongju Osong Station,' but experienced conflict due to opposition from residents who flowed in from the Seoul–Gyeonggi Area. This shows that the movement of the real estate market can be fragmented according to interests within the region. Furthermore, he emphasized that while the Technopolis area in northwestern Cheongju is popular, the Bunpyeong area in the south or Dongnam District have different market conditions, so they must be distinguished when judging unsold housing. Finally, he mentioned that, like the case of Wonsam-myeon in Yongin, the topography of a local community can change rapidly as land expropriation and compensation issues arise depending on the location of a specific company (SK hynix).
