Línea 2 Metro de Incheon

En Incheon, desde primeros de año que ya tienen los nuevos trenes para la línea 2 del Metro. Un poco triste porque será tipo LRT con unidades de dos coches. Estos coreanos y sus mamandurrias.

Un poco más de lo mismo, también este verano, pero en imágenes:



Y aquí sobre las vías en la estación de Yeongdeungpo en enero:



La previsión era inaugurar la Línea 2 este mes de Agosto y así servir durante los Juegos Asiáticos de Incheon. Hasta 2016 nada. Son 29.3 kilómetros y 27 estaciones. http://en.wikipedia.org/wiki/Incheon_Subway_Line_2

Línea 3 Metro de Daegu

Fotos de la nueva Línea 3 del Metro de Daegu... un monoraíl. Los trenes son de Hitachi. La previsión era abrir en otoño, vamos, AHORA, pero creo que lo retrasarán al final del año fiscal de 2014, el próximo marzo.

Interior:

Line 3 Monorail Finally Unveiled!

The City of Daegu finally unveiled its monorail, which is to run along Line 3 of the Daegu Metropolitan Transit Network. The monorail, the first of its kind to be introduced in Korea, is equipped with state-of-the-art devices for unmanned operations. The monorail also features fire extinguishers, safe escape devices, and other amenities inside carriages for passengers’ security and convenience.

○ The Metropolitan Transit Construction Headquarters organized a special event on July 2 at the train base in Dongho-dong, Chilgok, unveiling to the public the monorail - its full interior and exterior designs - and the safety features and amenities it is equipped with.

○ Each monorail consists of three carriages and is 2.9 meters wide, 15 meters long, and 5.24 meters high. It can admit up to 265 passengers on average and up to 398 passengers during the busiest hours. The monorail, made of aluminum, comes with driving, guiding, and stabilizing wheels that move the car along its orbit beam. Because there is an exterior skirt surrounding the guiding and stabilizing wheels, the monorail makes considerably less noise that normal subway trains during operation. The car is also designed to minimize the transmission of its noise to the outside world.

○ As for the exterior design of the monorail, it is white on the upper part and grey on the lower part so that it looks its best against the backdrop of the yellow that marks Line 3. The front has been streamlined to maximize speed and harmonize with the urban landscape.

- As for the interior design, white boards form a clean atmosphere overall, while the smile-inspired chair shape and the flooring material of a different color also add warm and fun touches. The driver’s cabin, the legs of the chairs, and the passageways and doors between carriages are conspicuously absent, making the overall interior atmosphere spacious and clean.

○ Safety features inside each carriage include a sprinkler-type fire extinguisher, the first of its kind to be seen on a Korean subway train. The fire extinguisher automatically activates a mist of water upon detecting a fire. Because it uses water only, it poses no harm to the human body and can be used to extinguish fires of all type, whether caused by electricity, oil, or other igniters.

- Should the monorail come to a halt due to an unforeseen defect or breakdown, the emergency exits, the safety footstools, and the spiral shooters are activated automatically so that passengers can safely flee the monorail and the underground.

- Each carriage is also equipped with two closed-circuit surveillance cameras, with the images of the inside of each carriage transmitted to the central monitoring station on a real-time basis. In addition to the central monitoring station that automatically and constantly monitors the conditions inside and outside the monorail and takes appropriate measures without delay in emergency situations, the safety system also includes such devices as emergency interphones and broadcasting equipment.

○ To ensure every passenger’s comfort, the monorail comes with two special areas for wheelchairs. In addition, 21 seats (or 24 percent) of the 89 seats on the monorail are set aside for the elderly, the disabled, and pregnant women. These seats are given colors different from the rest of the seats so that they are easily identifiable. Vertical handrails are found at the halfway point of each row of chairs and in the middle of the foremost carriage so that passengers can hold on to them.

○ As Line 3 runs along an overpass above the ground, the side windows on the monorail have been enlarged so that passengers can take in as big a view of the outside landscape as possible. The seats have also been widened from 430 millimeters to 460 millimeters, given the increasing average size of Koreans. There is no passageway between the carriages so that passengers can move from a carriage to another without any difficulty.

- The windows become automatically blurred when the monorail runs through residential districts and neighborhoods so as to protect the privacy of locals living in those areas. The window blurring option can be set so that it is activated only in certain districts or intervals according to the route information and signals saved on the computer system inside the monorail.

- The monorail is markedly different from conventional subway trains in that it has no driver’s cabin. An observatory has been installed in place of a driver’s cabin so that passengers can enjoy views of the outside landscape in front of the monorail.

○ The monorail for Line 3 was manufactured at Cheongwon-gun County in Chungcheongbuk-do by Woojin Industrial Systems, using techniques and major parts imported from Hitachi, the Japanese company that has produced the most and best monorail cars in the world. After functional tests and a driving performance review at the train base, the Korea Railroad Research Institute, a government-designated, performance-testing agency, will launch technical and commercial trial operations in October. Once the monorail’s performance and safety are confirmed, its operation will begin in the latter half of 2014.

○ Mayor Kim Bum-il of Daegu announced: “We will do everything we can and run thorough checks, trial operations, and inspections to ensure that the monorail for Line 3 becomes the world’s best and safest light subway train.”

De hecho llevan desde primeros de 2014 probando los trenes:



Estas son un poco más recientes.

En la página web del proyecto pueden verse algunas especificaciones técnicas: http://www.krri.re.kr/teams/urban/advan ... rch_01.htm





Son unidades de seis coches, todo continuo. Hay diferentes diseños interiores en función de las necesidades:







Hay cosas que me chirrían. No se dice por ningún lado la longitud de los coches. Lo normal en Corea para trenes commuter son 19,5 o 20 metros por coche con cuatro puertas. Las mamparas en los andenes se ajustan a eso. Lo que veo en las fotos del diseño da la impresión que son algo más cortos que 19,5. En Busan los trenes son de 17,5 y 18, igual ahí podrían ir.

En todo caso no deja de ser un prototipo.

HEMU-430X



Esta noticia aparecía hace unas semanas en el KBS News 9 de la televisión pública coreana (ver aquí a mayor calidad)



En la noticia discuten sobre la velocidad media y tiempo total de viaje en una simulación de pruebas del HEMU-430X haciendo el viaje Seúl - Busan con paradas comerciales en Daejeon y Dongdaegu.



El HEMU-430X es un tren experimental diseñado por Hyundai Rotem que hace poco alcanzó la velocidad máxima de 421km/h tras seis años de desarrollo y un presupuesto de 110 billones de wons (81 millones de euros) ... el plan contempla acabar la investigación el próximo año y que sea capaz de hacer el viaje entre Seúl y Busan en 90 minutos. Esto se reclamaba en 2011 en un documento oficial.



Pero con esta simulación a 350km/h el tiempo de viaje ha quedado en 1 hora 54 minutos (creo que alrededor de 3/4 de hora menos que el mejor tiempo actual) y una velocidad media de 219 km/h. Todo esto considerando los nuevos accesos de alta velocidad de Daejeon y Daegu, y también la nueva LAV de Suseo y Honam.





En todo caso subir la velocidad ya no a 400 km/h que permitiría llegar a los 90 minutos entre Seúl y Busan, pero sí a la simulación a 350 km/h de velocidad punta, costaría seis veces el presupuesto del desarrollo del HEMU pues es necesario mejorar las señales, etc. Sumaría 670 billones de wons (500 millones de euros) ... y no parecen estar por la labor de momento.

Además...

Tras 10 años en servicio, los KTX-I derivados del TGV Réseau parece van a tener un lavado de cara, alguna foto de cambio de tapicería en los asientos he visto. ¡Menos mal! ya daba asco.
