I don't like the front look, but I like the rest.

A Webzine by KRRI(Korea Railroad Reserarch Institute) reported the process of HEMU-400 design in details.

Here're some pictures.



Above trains were final candidates and 3rd train was selected.
2nd train is duplex type.

And to answer one last time to agaristagari:
If you would be live in Europe, you would be interested by the TGV saga and its look. External design contributed greatly to its success and you would know also that each operator looks for identity, so before being mad, calm down and read previous threads on this forum. Look is one of the functions of design and only the signature, but it is an important one. Of course, engineering is important too. But nowadays, when all technical parameters, requirement, reach the top, confort, practical and are around similar budgets, how can you choose? Design also works on identity and culture and helps to sell.

Although I do not read Korean so have no idea what is written within the link but I believe the CGs are nothing more than eye candy which may or may not be developed within the next 5 years. In other words vaporware.
Does the link provide any target dates?

To my knowledge Rotem does not have any prior experience in developing HSR EMUs meaning they will face many technical challenges ahead.
In Japan even with the vast experience, needed the Fastech 360 as a testbed in proving new technology which is scheduled to be incorporated into the E5 series. The front design went through countless computer simulations and wind tunnel testing but still had to go through actual testing utilizing two sepreate designs to determine the final design.

Do you think HEMU-400 will work exactly as they had drew on the drawing board?
I doubt it.

The target date is 2012. Of course there would be many obstacles in their way and the results could come shorter than their orignal targets, but anyway they announced it will be developed by 2012. The day we show it running on tracks would be the remote future, even if it will be successfully developed, because they should use KTX and KTX-II at least for 25 years or more.

come on guys, have faith in Korean....arent's that some of our latest search engines features and consumer electronics patents (from mobile entertaiment to new washing machine technology) were origin from the koreans? yes, yes, yes.. despite those services later were standardised by yahoo, google, apple or the americans.

[Huhu]

Great pictures of the workshop.

Hopefully in the not-too-distant future there will be KTX to Pyongyang, Wonsan, and Sinuiju, with connections to CRH to Dandong, Shenyang, Beijing, etc.

Oops, why the driver seat is not in the middle position of the window? It cut a big part ov vision, although I know that it is not as fundamental as for other vehicules... It seems that the driving place has not designed in relation with the new exterior design... Like if it was wade for the old TGV with two windows... Strange. The rest looks very fine. But here obviously, there is something i don't understand...

[honwai1983]

I wonder why KTX still use Electric Locomove Unit?
That kind of train is not suitible for hilly suitation of South Korea!
This is the Age of EMU!

I think it seems particularly narrow because of the angle. Korail required the driver's cab be similar to KTX(different from HSR-350x, the prototype of KTX-II, which has a digitalised and centered gauge board) so that KTX driver could operate KTX-II without problem.

Because south korea don't have EMU-type high speed train and KTX doesn't have any problem to run 300km/h on this mountainous land because most of railways is not up-hill, rather it run through elevated or tunneled railways and KTX's gradability is, even if there's up-hill, enough to climb it. It's sure that EMU High-speed train is the current trend but not a must-have.

It's good it's not an emu, locomotive trains are better.

As you can see on this page, the next generation of Korean high speed trains, the HEMU-400 has an EMU design.

The KTX-II is based on the HSR-350x and that was based on the original KTX, that was an Alstom designed TGV. So it's just an outcome of a development that was started by the Korean Railway Industry to become the next country to develop a High Speed Train. Now with the HEMU-400 they can start to develop a new train that is not indirectly based on another train.

As you can see people the Korail launched they future model the HEMU 400X and theres no locomotive like KTX 1 AND 2 its EMU type that the driver seat is also on the passenger cab. Well the target year for this HEMU 400X is on 2012.

[riles28]

I can see the HEMU 400X is also can run in trunk line.

Who decided that TGVs don't count as electric multiple units and why?

The cars that form a complete EMU set can usually be separated by function into four types: power car, motor car, driving car, and trailer car. Each car can have more than one function, such as a motor-driving car or power-driving car.

* A power car carries the necessary equipment to draw power from the electrified infrastructure, such as pickup shoes for third rail systems and pantographs for over head systems, and transformers.
* Motor cars carry the traction motors to move the train.
* Driving cars are similar to a cab car, containing a driver's cab for controlling the train. An EMU will usually have two driving cars at its outer ends.
* Trailer cars are any cars that carry little or no traction or power related equipment, and are similar to passenger cars in a locomotive-hauled train. On third rail systems the outer vehicles usually carry the pick up shoes, with the motor vehicles receiving the current via intra-unit connections.

Is this your opinion or fact?

[zergcerebrates]

KTX II 's front is way better than the first (well duh) the first KTX I frontal design is too dated.

Maybe because the configuration is that of a Push-pull.

Push-pull is a mode of operation for locomotive-hauled trains allowing them to be driven from either end. A push-pull train has a locomotive at one end of the train, connected via multiple-unit train control, to a vehicle equipped with a second control cab at the rear of the train. In the UK the control vehicle is referred to as a Driving Trailer or Driving Van Trailer (DVT), while in the USA they are called cab cars. Alternatively, the train may have a locomotive at each end.
