Bullet Train Construction Bidding to Pick-up

Bullet Train Construction Bidding to Pick-up
New, page 2

~ Invitations to bid on for freight train production will be sent to locomotive producers in June, followed soon after by invitations to bid on bullet train production. However, the specific date for the latter is still unknown.
~ Bullet train production has been at a virtual standstill for the two years since the train crash in Wenzhou on July 23, 2011 that killed 40 people. Most railway lines and carriages under construction were delayed for safety concerns, which worried suppliers of railway equipment.
~ Because of speed reductions mandated after the crash, the number of bidding invitations issued for bullet trains has declined in recent years, while invitations for other kinds of carriages remained flat.
~ Assessment of bidding companies for their technological research and development ability, quality assurance and technology management have now been stopped. The coming bid invitations are expected to give many private companies new opportunities.
~ The biggest change for the coming bidding is that who will be invited to bid will now be decided by local railways bureaus. This is because under new railway reforms, local railways bureaus now have more management, investment and construction rights. After these bureaus decide on who can bid, China Railway Corporation will collect the information and then release the invitations.
~ It's estimated that the bidding will affect construction of over 400 new trains.

Which month of 2014?

Does the railway go through central Nanchang, or elsewhere?

When the railway opens, which shall be the shorter route Nanchang-Beijing: Nanchang-Changsha-Wuhan-Beijing, or Nanchang-Hangzhou-Nanjing-Beijing?

I will have to spy on them to make sure I'm not wrong, thanks for clarifying.

That's exactly what I was thinking, most of the times the layer inside the vehicle(in cars) is intact or hardly cracked.

So according to the article MOR ordered around 1300 high speed EMU trainsets since 2004, with 2009 at the highest with bidding for 770 trainsets, 2010 and 2011 were the lowest with 50 and 40 trainsets respectively. Orders picked up in 2012 with 230-240 trainsets. They are predicting that the next bidding will be for around 400 trainsets. Also estimated is the delivery schedule for the next three years (2013-2015) at 315, 225, and 114 trainsets.

1. The end of 2014.

2. It'll stop at Nanchang South Station.

3. Good question. I don't know but it seems the same distance either way.

Japan tests 310mph bullet train

Quote:
Japan tests 310mph bullet train
Japan's "floating" trains of the future, designed to travel at speeds of 311mph, have undergone their first test tracks.


The new train, designed by Central Japan Railway Co (JR Tokai), will initially link central Tokyo with Nagoya station

By Danielle Demetriou, Tokyo1:08PM BST 04 Jun 2013

The new generation L0 Series trains, which employ the latest magnetic levitation technology instead of conventional wheels, will begin commercial services in 2027.

The first five cars of the new train, which has a distinct aerodynamic "nose" at the front, were displayed on a test track in Yamanashi Prefecture.

The carriages, which are propelled by magnetic forces, were pulled along the track by a special maintenance vehicle as part of preliminary trials, with wide-scale tests due to commence in September.

The new train, designed by Central Japan Railway Co (JR Tokai), will initially link central Tokyo with Nagoya station, cutting current bullet train journey times by more than half, from 90 to 40 minutes.

The final train will consist of 16 carriages carrying up to 1,000 passengers at a time, with plans under way to extend the line to Osaka by 2045. The plan is ultimately to create a high-speed mass transit maglev network across the country.

It was in 1964 that Japan was propelled to the forefront of transport technology after it unveiled its first bullet train – known as "shinkansen" – to coincide with its hosting of the Olympic ames.

Since then, Japan has become famous as home to the world's most sophisticated rail network system, with bullet trains travelling at speeds of up to 199mph across more than 1,400 miles of tracks.

Shinzo Abe, the prime minister, is currently pushing for a surge in sales of Japanese road, railway and power station technology to emerging nations such as India, which is expected to use Japan's bullet train technology for a new Mumbai to Ahmedabad line.

Today, with close to 60 years passing since the first bullet train was launched, Japan is investing heavily in maglev technology in order to remain at the forefront of rail engineering.

Competition with China is already strong, with the Shanghai maglev train capable of travelling at a top speed of 268mph – although its average speed is 152.5mph due to the limited length of the track.
I know it is OT, but just look at that! I wonder what would be the reply from China? Another announcement of the extension of Shanghai's Maglev?

An extension would be awesome. I remember seeing in previous posts there is fear among residents that maglev is harmful to peoples heath.

It makes me wonder why Japanese would go for maglev at 311mph(500km/h) when technology like the CRH500 exist, same speed.

Letīs count the distances Shanghai-Guangzhou

On existing lines:
Hongqiao-Nanjing South - 311 km (via Suzhou and Zhenjiang), 300 km/h; via Suzhou North would be 295 km
Nanjing South-Wuhan - 516 km, 200 km/h
Wuhan-Guangzhou South - 968 km
total, at least 1779 km, of which 1263 km is 300 km/h and 516 km 200 km/h.

From end of 2013:
Shanghai-Hangzhou - 169 km, 300 km/h
Hangzhou-Ningbo East - 150 km (?), 300 km/h
Ningbo East-Xiamen - 821 km, 200 km/h
Xiamen-Longhua - 502 km, 200 km/h
Longhua-Guangzhou South - 102 km, 300 km/h
total looks like 1744 km, of which 1323 km is 200 km/h and 421 km is 300 km/h

From end of 2014:
Shanghai-Hangzhou - 169 km, 300 km/h
Hangzhou-Changsha - 933 km, 300 km/h
Changsha-Guangzhou South - 621 km, 300 km/h
total 1723 km, 300 km/h throughout.

Can anyone check the real terminus of Hangzhou-Ningbo high speed railway in Hangzhou, and what shall be the distances Ningbo-Shanghai and Ningbo-Nanjing on 30th instant?

There are 25 days left to 30th instant. Has anything been disclosed of the Nanjing-Hangzhou-Ningbo high speed railway schedule?

Basically, conventional high speed rail (steel wheel on steel rail) maxes out at about 220mph- above that speed, aerodynamic drag takes it toll and operating costs become too high to run a viable service. Unless Chinese engineers somehow are able to cheat physics, we will not see 311mph high speed trains anytime in regular revenue service.

so are you saying 500kmph train could never put into commercial service as long as steel wheel/rail are being used?

They will open the complete line from Shenzhen North (Lonhua) to Xiamen later this year? Many of the viaducts are not even completed yet in Shenzhen...

How many trainsets were delivered and in service by the end of 2012?

How do the lengths of new opened railways in 2013, 2014 and 2015 compare with lengths of existing railways at the end of 2012?

And shall the new delivered trainsets be sufficient to serve the new opened railways in 2015, and leave enough over to increase frequencies on already opened railways?

Not to be mean, but have you been reading anything at all in this forum?

It's been discussed to great leangth the extent to which high speeds with conventional technologies are possible due to the limitations of several factors.
Things like wire wear, trackbed stabilizing etc. (Not to mention the horrible, HORRIBLE centrifugal forces the wheels would be going through at those high speeds. It's possible, but just scary to think of))

lol. Aerodynamic drag is same for maglev, too.

Also, technological development will always surprise you. It is not "cheating physics", it is understanding it better.


In the long term (min 30+ years), next step should be "vactubes".. we will see.

People just wonder whether the new maglev in Japan will be financially viable.

Holy crap that look like a platypus with a very long beak.....



I wonder what will be like to add some canards to help alleviate the weight on high speed trains, will they go airborne if they suddenly hit a gush of wind in the opposite direction?

Nothing, China and Japan are not engaged in any type of HSR arms race. The current CRH trainset meet China's needs so that's what China will be working on for the foreseeable future. The original proposal was an extension of the Shanghai Maglev to Hangzhou, but it was first stalled due to public opposition, and now made moot by the Shanghai-Hangzhou conventional HSR.

Regarding higher speed conventional trains, the CRH500 was made specifically for the engineers to understand the physics involved at very speed better. A conventional train probably will never operate commercially at 500km/h, but CRH500 will allow engineers to develop technologies that one day may enable them to run trains at speed such as 380 and 400km/h economically.
