Sorry, for Dongdaegu is a major redevelopment project for station area. BTW they are covering the end of platforms.

Does anyone know about plans for HSR-dedicated section in Seoul?

Well, there is the new Suseo HSR being built from near Pyeongtaek to Suseo-dong in southeastern Seoul. I'm assuming that that's primarily being done to reduce congestion on the Gyeongbu HSR north of Cheonan-Asan all the way to Yongsan and Seoul stations in the north-central part of the city, even though it's supposedly to provide better access to KTX service to people living in southern Seoul and the southern parts of Gyeonggi-do.

So to answer your question, yes, there is another dedicated high-speed line being built into Seoul. Surely, that will help with trip times, as well, considering how busy the Gyeongbu line is.

Government announced a counterargument :

Quote:
국토교통부는 27일 KBS 9시 뉴스의 “고속철 ‘해무’ 개발해도 시속 219㎞ 불과…왜?” 제하 보도 관련 “서울-부산 219km/h는 서울-광명, 대전 도심, 대구 도심의 일반선 구간이 포함된 결과로 광명-부산의 경우 평균 238km/h(1시간 40분)”이라고 밝혔다.

또 해무는 국내에서 처음으로 개발한 동력분산 방식의 고속열차로서 동력집중식(KTX)에 비해 대량 여객수송 및 정차역 간 속도향상에 유리해 운영효율이 뛰어나다고 덧붙였다.

참고로 해무는 편성당 좌석수가 동력집중식(KTX-산천) 대비 16% 늘어나며 300km/h 가속시간도 KTX-산천 대비 1분 42초 단축할 수 있다.

해무는 해외 및 국내의 고속열차 시장 수요 추세(250~350km/h)에 대응하기 위해 개발해 시운전, 검증 중에 있으며 지난해 3월 최고속도 421.4km/h로 세계4위를 기록한 바 있으며 올해 9월에는 시운전 8만 8000km를 달성했다.

국토부는 해무의 경우 설계 최고속도 430km/h, 운행 최고속도 370km/h까지 기술확보를 위해 설계·검증돼 준고속차량에서 고속차량까지 다양한 속도 대역의 고속차량 발주에 맞춰 제작이 가능하다고 설명했다.

국내는 신규 건설 추진 예정인 서해선, 경전선 등에 250km/h 내외의 준고속차량 수요가 있으며 동력분산식 차량이 주를 이루고 있는 해외 고속열차 시장에서 다양한 속도 대역의 차량이 발주되고 있는 상황이라고 덧붙였다.

최근 5년간 해외 고속차량(200km/h 이상) 발주는 동력분산식이 76%를 차지하고 있다.

이와 함께 국토부는 600km/h급 고속열차 기술개발은 미래부 출연금으로 한국철도기술연구원이 자체적으로 수행하고 있는 과제이며 초고속 핵심기술개발이 목적인 과제로 시제차량은 제작하지 않는다고 밝혔다.

국토부는 아울러 전국 1시간 30분대 연결이란 의미는 경부·호남·수도권 고속철도 개통과 주요 일반철도 고속화를 통해 지역간 접근성을 개선하는 계획으로 이를 통해 1시간 30분대 지역 간 이동가능 인구를 현행 60%에서 83%로 면적은 30%에서 76%로 확대하는 것이라고 설명했다.

source
The scheduled speed reported (219 km/h) includes running on conventional track in Seoul~Gwangmyeong, Daejeon and Daegu section. The scheduled speed, if calculaing bewteen Gwangmyeong and Busan, is 238 km/h (1 hour 40 minute).
.
.
.
The plan to connect major cities in 90 minutes means that areas and populations travelling each cities in 90 minnues s or less will be expanded to 76% and 83% from 30% and 60% respectively by enhancing accessibilities with Gyeongbu, Honam and Suseo HSR and speed-up of conventional railways.

Suseo HSR was originally scheduled to open next year along with Honam HSR, Daejeon and Daegu dedicated track but delayed to 2016.

As of now (20th of October 2014) the construction of Suseo HSR has been 61% complete.(source from KR)

I hope they do something really special with the Suseo HSR station. Anyone know of any renders?

Some proposals. Imagine what they choose finally.

Honam HSR in Jangseong

Honam HSR track in Jangseong. It was foggy in the morning.


I waited for 3 hours to take a picture of Honam HSR test running, but only saw that inspection cars come and go several times.

Great! Does this mean that the Honam HSR line is officially open?

It seems strange to me that they went with ballasted track on a brand new line; I thought that ballastless track was supposed to be superior in a lot of ways. A quick Wikipedia lookup suggests that maybe they went with ballasted for reasons of passenger comfort? Any other ideas?

No the Honam HSR line is still under construction. The new HSR line will also pass through this station, but at the time only the "old" Honam line is in service.

I think the HSR line is supposed to open in March 2015 (up to Gwangju, not the Gwangju-Mokpo section)

Ah, I see. Well, once that's done, all we'll need to have really good coverage of most of South Korea's population is a Gyeongjeon HSR line. 2020 can't come fast enough.

Just a question, if the North were to collaborate on a HSR project ,as a goodwill of some sort, how long will it take to complete 100% Seoul-Pyongyang-Bei Jing HSR Line.

Consider that there's no political barriers for the project ,just the terrain and language problems.

First, that's not gonna happen any time soon, so don't count on it.

Second, language will hardly be an issue. There are multibillion dollar contracts pretty much every day involving different countries and languages. Sure, you need translators, politicians and legal teams to make any transnational project work, but it's not as big a political hurdle as civil engineering, negociating, technology development and... financing.

The good thing about rail projects is that the overall cost is not overly related to the time to construct such a project. In a skyscraper construction, you can build the N+1 floor until you've worked on the Nth floor, so ever taller buildings mean ever longer construction times.

For rail, the longer the rail line, the more teams you can put on the construction of the line (on different places along the line), so assuming you're building a 1000km line, it's not gonna be 10x slower to build than a 100km line, as you can start building it at different points along the line.

That being said, it's a huge project. Seoul-Pyongyang is over 200km, Pyongyang-Shenyang is over 400km. The line would then probably merge with the Beijing-Shenyang HSR line under construction.

Given a timeline is impossible. Building the damn thing would take maybe 5 years, but that would probably require at least 10 years of preparation, planning, negociations, financing, studies,...

So yeah, if today Seoul, Pyongyang and Beijing governments came together and said "let's build this", it would probably take 10 to 15 years at least. But we might be 30 or 40 years before the governments agree on that

Not to mention that going up through the whole peninsula and then through Manchuria is a pretty roundabout way to get between two cities that have dozens of direct flights every day.

Even assuming that line happens (I wouldn't bet against it happening eventually), I don't think that'd be a very popular trip; it's like from London to Oslo. Even assuming a >300km/h line is built between the two of them, most people would just fly because geography works against land routes.

Exactly, I voluntarily left out the economic feasibility argument, but a Seoul-Beijing trip would probably take 6 hours if not more, so it would be much more efficient to board a flight to Beijing that takes less than 2 hours.

The line would make sense for subsegments (people traveling from Seoul to Pyongyang or Pyongyang to Shenyang or Pyongyang to Dalian), but not for the full trip for Seoul to Pyongyang. Of course, with the state of the DPRK's economy, the market and passenger base for international high-speed transport out of Pyongyang is tiny, so until North Korea opens up to foreign influences and starts growing considerably, such progress would make little to no economic sense.
