lol, you will become tomato sauce in seconds.
Though the more likely result is when you reach the track, automatic sensor mechanism will warn the whole system and all trains will stop.


They worked in the compartment as if on the land!
Very stable according to @铁路小亨 who was on the train.
:tup:

Andrew, do you know what is the spacing distance between tracks?
Technically when a train moves at such high seed, it creates an air whirl (or eddies) around it. So when two opposing trains come (with individual whirls), the counteracting wind force, tries to push the other moving mass laterally causing sway vibrations, affecting stability. The only known method to counter this is by increasing the spacing between center lines of two tracks, leading to cost escalation
But with China now becoming world leader in HST, i won't be surprised if Chinese railroad engineers have employed some new technology. Do share if u have some information on the same!

Next steps
Operational test on Harbin-Dalian HSR
3 new units of standardised CRH will be finished soon.
The official name of these two types of EMUs? Soon!

The test was conducted on the Zhengzhou-Xuzhou HSR (part of the Silk Road HSR)
which is due to open in September 2016.

This high-speed railway with operational speed of 350-380km/h will be another milestone in China's HSR development history. With its inauguration, the total mileage will surpass 20,000km!

This Zhengzhou-Xuzhou HSR should be extended to Liangyungang as early as possible!:fie:

Next time, please read the post more carefully. I mentioned clearly in #1 that:
- this is a crossing test
- 840km/h refers to relative speed of the two trains
- the train itself travels at 420km/h (see the pictures)

Also, pls show at least some basic respect to the work of the engineers/research staff of China. Thanks.

" 840km/h....setting a new world record" irritates the fragile nerves, so skipped over word like crosing test, relative speed...

Oh, i didnt mean standing on track, rather the idea is standing in the space between two rail tracks some thing like this

There cross air will create a vortex and chances are that anything in between this to track to levitate and thrown out :)

You are right.
The higher speed, the bigger space.
Normally for 350km/h HSR in China, it is 5m.
For 200-250 km/h, it is 4-5m (4.6 m normally).

Two Chinese trains dashing at world-record speeds in opposite directions passed each other on parallel tracks on Friday, in the latest feat achieved by China in high-speed rail.

At about 11:20 am, the two trains, "Golden Phoenix" and "Dolphin Blue," traveling at 420 km per hour, crossed on lines between Zhengzhou in the central Henan Province and Xuzhou in the eastern Jiangsu Province.

The experiment set a world-first for trains traveling at such speed, Zhou Li, head of the technological management department of China Railway Corporation, told Xinhua.

Zhou said the achievement, using homegrown trains, demonstrated that China has fully mastered the core technology of high-speed trains.

I understand it was raining, but could they just wash the Golden Phoenix a little bit? Dolphin blue is much cleaner!

Chinese bullet trains cross in historic first
Source: Xinhua | 2016-07-15 18:20:54 | Editor: huaxia

BEIJING, July 15 (Xinhua) -- Like an Einsteinian thought experiment, two trains, each travelling at 420 km per hour in opposite directions, whizzed along and passed each other on parallel tracks on Friday in the latest astonishing achievement by China's high-speed rail.

At about 11:20 a.m., "Golden Phoenix" and "Dolphin Blue" met and passed one another between Zhengzhou in Henan Province and Xuzhou in Jiangsu Province.

MIND THE GAP

These "China-standard" trains, officially known as electric multiple unit (EMU) trains, are the first in the world to cross at such a high speed, according to Zhou Li, head of technological management at the China Railway Corporation, the national rail operator.

The gap between the two trains was only 1.6 meters when they met and the passengers, mostly technicians and journalists, felt only the slightest of jolts during the encounter. At a relative speed to one another of 840 km per hour, these trains are effectively travelling at the same speed as a cruising airliner.

What makes the event even more extraordinary is that Golden Phoenix and Dolphin Blue were both actually two trains coupled together, different models made by different companies, both subsidiaries of China Railway Rolling Stock Corporation (CRRC).

Coupling such trains is very demanding technologically, in terms of synchronized pulling, braking and other key events, said Zhao Hongwei, chief researcher at the China Academy of Railway Sciences.

China began working on EMU trains in 2012 and in June 2015 the results of three years of intensive R&D were unveiled. The first EMU hit 385 km per hour later that year.

Tests like "coupled running" are designed to unify standards and reduce costs. They help make the train versatile enough to be run in many different environments, Zhou said.

China's EMU fleet of 2,395 trains is the world's largest and the total length of high-speed track in the country -- 19,000 km -- represents 60 percent of the global total.

NEXT STOP, THE WORLD

The success of the test shows China's mastery of the core technology needed for high-speed EMUs, Zhou told Xinhua. This is very significant for the branding and marketing of Chinese high-speed trains. China-standard EMU trains will be the leading model in the global marketing campaign.

The model can be adapted to various geological and operational situations, including extreme climatic conditions, a core competitive strength in the global market, he said.

Fully-automated traction, braking and network control systems outperform all rivals, Zhou said.

Chinese bullet trains have already found international customers in Indonesia, Russia, Iran and India.

Construction of a 150-km high-speed link between Indonesian capital Jakarta and nearby Bandung began in January 2016. It will cut travel time between the two cities by around two thirds. The project is almost entirely Chinese, including technical standards, survey and design, construction, equipment manufacture and personnel training. It is the first full-package overseas deal for China's high-speed trains, which should be running between the two cities within three years.

In 2014, the China Railway International Group was established to pursue railway cooperation between China and other countries. China's overseas railway strategy has picked up speed in recent years and Chinese companies are now actively seeking cooperative projects in Malaysia and Singapore, Mongolia, the United Kingdom, the United States and throughout Africa.

840 km/h? that is suicide speed. Only legal in China because they only care about speed.
Maybe if you're Vietnam, but we all know you don't have the engineering capability to achieve such feats.

:o:420km/hr? man that really sounds scary isn't 250-300 enough? :fie::fie::fie:
Historically, transportation speed is ever increasing. When your grandchildren looks back at you 50 years from today, they'd probably think 420km/hr is slow as a turtle.
