CHINA | High Speed Trainsets

Will there be a direct Nanjing-Ningbo G-train?

Why are the wheels yellow?

DJJ1 Blue Arrow is a much more successful domestic HSR project than China Star, it operated for 13 years until Dec 2012 when all eight trainsets reached their operational life and were removed from service (Guiyang-Liupanshui) for evaluation.

These are instrumented wheelsets. I guess.

I've never heard about this train. It looks really cool. The cars look like the cars on the CRH1.

There are some pretty cool videos of DJJ1 running at full speed (supposedly 220km/h). It was, if I'm not mistaken, the first 'real' HSR trainset to be used on Guangshen railway

Yeah this and the DJF2 Pioneer are my two favorite domestic HSR trains, the latter is a true high speed power distributed EMU which set a 292.8 km/h record in 2002. A lone trainset was built and operated commercially until it was retired to Nanjing Institute of Railway Technology last year.

The first one would be the imported x2000.

[FM 2258]

Thanks for the video pansori and picture hmmwv! Were these trains just really inefficient compared to trains like the CRH1? Also did these trains get the D designation?

[Pansori]

Yep, I just did some reading about X2000. The train in the video is not a DJJ1 but a X2000 which is a Swedish design. I never knew China has imported Swedish HSR (or quasi-HSR) technology.

So is DJJ1 somehow related to X2000? DJJ1 is a loco-hauled train while X2000 looks like an EMU which makes it somewhat impossible/unlikely.

Also, isn't China Star developed on the basis of DJJ1?

DJJ1 is China's first high speed EMU that entered serial production so understandably there are lots of issues with them, they are generally speaking pretty good but definitely not as good as mature products from world class train makers. DJF2 was reportedly even better with all the right ingredients of a modern high speed EMU, it's regarded as a mini 300 Series Shinkansen due to imported Japanese technology. It was however born at the wrong time since by the time i passed all MOR trials the ministry under Mr. Liu had already decided on adopting imported foreign technologies. I don't blame him given how willing those train makers were to share technologies, if I'm MOR and all the sudden I realized I can get all those technologies for virtually free I'd jump on it too.

Nope that video is the DJJ1, the x2000 looks completely different (see pic below). What you see first is the rear car, the loco was pushing from behind. The DJJ1 is not related to the X2000, which is a loco-hauled tilting train. X2000's success on Guangzhou-Shenzhen line persuaded MOR to start the development of a domestic high speed train. The x2000 simply can't compete with those CRH trains later and was sold back to Sweden last year. DJJ2 China Star is a follow up project of DJJ1 and there could be some technology inherited, but I don't think it's designed based on DJJ1.

500km/h CRH to be tested with three U/C HSR lines

Testing tracks will be constucted with Hangzhou-Changsha, Datong-Xi'an and Zhengzhou-Xuzhou HSR lines. No date is specified yet.

Would that be a test to achieve record speed or just an ordinary trainset/line testing?

I can't wait to see a video of this train running at extreme high speed. Seems hard to find information about this train. Hopefully they've figured out how to run this thing at 500km/h economically.

Well it's not designed to operate economically at 500km/h, it's simply an experimental train to explore technological innovations for very high speed trains. What it hopes to achieve is to develop technologies that will trickle down to commercially available HSR trains to make them safer and more efficient.

Precisely!
