Many places of china do change so fast .If you have a trip for some city you will be deeply impressed by this change.As a boy from wuhan who work in Beijing ,I feel the tiny change of hometown some of them are good ,the other not.even though some old building disappeared,I am glad to see a very different hometown.

 

[gslv]

Congratulations china.

 

[Asfandyar.Khan]

Congrats from Pakistan. Keep on it

 

[shah1398]

Chinese always remember Pakistan's generous help during 2008 earthquake, much more precious than money. Wife may leave when husband is in crisis, but friendship during hardship mirrors one's genuine heart.

Friend in need is friend indeed .

I don't know the exact number, but I think they can be categorised into several types,

1, China Academy of Railway Sciences
Highest, organise research and railway projects across China
View attachment 233244

2, Regional academies of railway sciences
belongs to regional railway bureaus or directly to Ministry of Transrpot
For example, Harbin Railway Technical Research Institute

3, Railway Universities and their attached research institutes
10 national railway universities which belonged to formal Ministry of Railway, all became independent in 2000.
For example, Southwest Jiaotong University (jiaotong=transport) and its State Key Laboratory of Traction Power

4, CRRC and its numerous research institutes
Formal China North Railway and China South Railway
One of the most famous institutes is CSR Zhuzhou Institute
China develops cutting-edge Permanent-Magnet Synchronous Electric-Machinery Traction System for High-Speed Rail - RailNews

5, CRCC(China Railway Construction Corporation) and other state-owned railway construction companies with their research departments.

6, Regional railway colleges and their attached institutes

7, Railway-related institutes, such as materials, electronics, etc.

etc.



By CNR. Domestically, they still have to compete, even institutes and companies within CSR have to compete with each other. Railway fans kind of dislike this 土豪金 design, but I like it, what's your opinion?

I think CRH3(based on Siemens) is the ugliest bullet train, thank god, CRH3 is seldom seen in Wuhan! Good news, CRH3 and other trains based on foreign designs will not be largely manufactured anymore.

No wonder you are so advanced in rail technology hopefully joint Sino-India dedicated rail university in India will help us achieve more self reliance in this field

The Hefei-Fuzhou high-speed railway started to sell tickets on Saturday, which will operate on Sunday and shortens the travel hours from Hefei to southeast China's Fuzhou to within four hours.

The interiors look quite pleasing to my eyes。

Hard to count。

There are institutes, academies, colleges and universities that specialize in railway sciences and technologies。



Is this the CRH350 prototype by the old CNR or CSR？

中国350公里标准动车组样车已经初步研制完成，由中国南车和中国北车各自制造的一列样车将于2015年6月下线。

青岛四方和长客各负责一列样车

　　中国轨道交通车辆企业相关人士对财新记者透露称，由青岛四方机车车辆股份有限公司（下称南车四方）和长春轨道客车股份有限公司（下称北车长客）负责生产的两列样车目前已经涂装完毕，正在做最后的场内测试，该车具有完全自主知识产权。

　　上述人士对财新记者强调，目前生产完毕的两列动车组仅是样车，样车下线后将交付中国铁路总公司进行线上试验，进行优化完善和试运考核等，这项工作耗时较长，估计将于2016年年底前完成。在线上测试工作完成后，两列样车将再次回到各自制造地，中国铁路总公司将联合南北车通过实验数据吸取两列列车的优点，完善并确定最终统型的中国标准动车组。

　　中国铁路总公司相关人士对财新记者表示，中国350公里标准动车组的研制工作由中国铁路总公司主导，时速分为250公里和350公里两种速度等级。中国铁路总公司与国家发改委协调后决定先期研制时速350公里标准动车组。研制工作从2013年开始，当年由中国铁道科学研究院牵头完成了中国标准动车组的顶层技术指标确定，2014年9月开始进入到制造阶段。

　　据了解，中国标准动车组从动力配置、牵引系统、制动系统、网络控制系统等9个方面提出了总体技术方案。上述铁总人士强调，南北车负责整车设计，软件实现全面自主化，动车组将统一旅客界面、司乘人员操作界面和检修维护界面；统一主要维修零部件，最终实现同一速度等级动车组可重联运营（将8辆编组的标准列组成16辆编组的长编列），不同速度等级动车组可相互救援等基本目标。

　　该人士还透露，未来，铁总将以中国标准动车组的研制为基础，为中国更高速动车组的研制创造条件（CRH450？CRH550？）；并在动车组主动安全防范技术上开展研究。同时通过中国标准动车组的研制提升中国企业在国际市场的竞争力，以高速动车组出口为突破口，带动工务工程、牵引供电、通信信号、运营管理等成套技术走出去，为中国高铁海外战略目标提供技术支撑。

　　早在2010年，原铁道部就发布过动车组技术标准，南北车按照标准，在各自的技术平台上制造出了“统型车”（对列车的车型、主要性能、服务设施、操作设施、定员等进行了统一设计）。目前，南北车共有4个技术平台的17种型号动车组，各车型在技术参数上均不统一。

统一标准后运营及维修成本有望降低

　　北京动车段一位人士对财新记者介绍，动车组型号众多，对路局动车段进行的一、二级维修造成很大困难，这些零配件不能通用互换，同时配件种类繁杂，维修成本高，难度大。他举例称，每型车的长度、架车点位置以及轴距、定距等都不一样。动车组架车工艺一直是检修中的难点，统一标准后，培训、维护、维修难度会得到相应降低，维修成本也将随之减少。

　　其次，统一标准后运营成本也有望降低。北京铁路局一位人士对财新记者表示，当前动车组普遍存在不同型号不能重联运行的问题，而为保证载客运营车辆的安全，各路局对动车组车次都会有热备车底（指设备完好、随时可以投入使用，但没有输入车次的动车组），而热备车底一般要与现役车底型号相同，这就需要路局针对不用型号的动车组各配热备车底。统一车型后，动车组备用率会大大降低，实现互联互通，也可以实现动车组间的相互救援，企业运营成本也会降低。

　　中国北车人士对财新记者分析称，当前每型动车组各自依赖单独的产品供应链，大量配件独家供货，价格居高不下，一旦技术标准统一，生产企业只要按照该标准生产并通过铁总的认证，就可以进入该部件市场。这将对国内众多生产企业形成利好，打破一些企业在动车组关键部件上的垄断局面。

　　目前，中国高铁运营里程1.6万公里，全路共有13个铁路局开行了动车组列车，建立了9个动车段，39个动车运用所。投用动车组1411列、13696辆。其中时速200～250公里动车组680列以上，时速300～350公里动车组700列以上；日均开行动车组列车2700余列，日均发送旅客超过240万人次；动车组累计运行里程超过16.7亿公里，单列最长累计运行里程达390万公里，单程开行距离最长达到2500公里。中国高铁运营里程、动车组保有量均占世界总量一半以上。

Got my answer from @AndrewJin but the anyways

 

[AndrewJin]

Got my answer from @AndrewJin but the anyways

It's a big industry, isn't it? Only one single ministry of railway cannot make it big. And their tech is not limited in railway sector, like this one, China develops cutting-edge Permanent-Magnet Synchronous Electric-Machinery Traction System for High-Speed Rail - RailNews (the future of train engines), which is already applied in Gree's A/C. From steel to electronics, every sector can be involved. Just look at how HSR industry works in Japan, Kawasaki and a lot of relevent companies are very competitive. Not just the proposed joint railway university, hope more industries and research institutes in India can get involved and along with other railway giants promote railway tech to a new level in the world.

 

[Echo_419]

Around 17000km, not many new lines open until now in 2015. Most new lines or upgraded old lines(>200km/h) will be open from October to December. In my hometown, almost all metros are inaugurated on 26-28th December.

Mind that some new lines which will be in trial in 2015 will be official inaugurated in Q1 of 2016.

From Wuhan? Miss home now?
Enjoy some photos on Wuhan I took on this Tuesday. I haven't walked on this Yangtze River bridge for at least five years. It was very enjoyable to walk with river wind blowing over your face, although it was over 32 degree Celsius.

Indeed you need a holistic approach to develop any industry

Here it comes：CRH350 prototype of the erstwhile CSR

CRH350 CNR vs CRH350 CSR，head-2-head

 

[IR-TR]

Sh1t. Pics don't show. Or is it me?

 

[ahtan_china]

What is problem?

 

[AndrewJin]

@cirr
I like CSR's standardised CRH350 a little more.
But both I think are cooler than CRH3 which is based on Siemens.

For the details of standardisation of CRH, u can search for the paper <坚持自主创新道路, 积极推进中国标准动车组研制> which was published in the August issue of China Railway, written by the former vice general manager of China Railway Corporation.

One section of this paper
中国标准动车组总体技术方案
中国标准动车组研制工作立足当前实际，着眼未来发展，在现有成熟技术实践基础上，采用正向设计的方式进行，坚持自主知识产权、安全可靠、标准化、系列化、简统化、经济性、节能环保等原则。总体技术方案如下。

（1）动力配置。采用8辆编组，4动4拖的统一动力配置形式由2个基本动力单元组成。通过调整电机特性，可在动力单元配置及网络控制等基本不变的情况下，满足不同速度目标值对牵引能力的需求，可通过不同动力单元的组合，实现灵活编组，满足不同的客流需要。
（2）牵引系统。采用大功率IGBT元器件构成的交直交传动牵引系统，通过提高中间直流环节电压，提高效率，降低损耗，改善电机控制特性，提升单位质量下的牵引输出功率。充分利用元器件性能，在牵引功率基础上显著提高电制动功率。利用移相技术有效控制谐波，保证再生能量的回收质量，降低总能耗。
（3）制动系统。采用微机控制的直通式电空制动系统及大容量基础制动装置，具备以整列车进行空电复合控制的能力，可按模式曲线精确控制列车减速或停车。由制动系统实施列车制动力的管理、计算和分配，优化防滑控制逻辑，充分利用黏着及电制动，缩短制动距离，减少盘片磨损。
（4）网络控制系统。采用列车级（WTB）和车辆级（MVB）组成的两级网络结构，按照适应我国铁路实际的控制策略，自主开发列车网络控制系统。列车增设诊断以太网，全面加强故障诊断和监测数据的传输，并提供向地面实时传输数据的功能，使列车的智能化程度大幅提升。实现不同厂家生产的相同速度等级动车组重联运营，不同速度等级的动车组互相救援。
（5）转向架。采用模块化设计的H形构架无摇枕转向架，强化结构及性能的安全冗余设计。统一采用920 mm的大轮径及磨耗型踏面，改善轮轨匹配关系，优化转向架两系悬挂参数，降低簧下质量，减轻轮轨动力作用，提高运行稳定性、舒适性及结构安全性。实现轮对等主要部件的统型互换。
（6）车体。采用大型中空铝型材焊接而成的高强度、轻量化车体，统一车体长度为25000 mm，车体最大宽度为3360 mm，车辆高度为4050 mm，空调等设备采取嵌入化设计，实现列车纵断面的平顺化，全新设计流线型车头，进一步降低高速运行时的阻力。设计防撞吸能结构和装置，提高安全防护性能。
（7） 辅助供电系统。采用中国标准制式的AC380 V/50 Hz辅助供电系统，具有自动平衡负载和冗余供电功能，辅助变流器由牵引变流器中间直流环节供电，实现过分相不断电、无动力回送/救援工况时自发电功能。研发锂电池直流供电系统，提升单位质量供电能力。
（8）高压系统。采用主动控制受电弓，高压设备外绝缘的雷电冲击耐受电压提升至185 kV，采用整体密闭的高压箱结构，除受电弓外，其余高压部件不暴露于运行环境中，以改善高压系统部件的工作环境，提高系统在不同网高和不同环境下的工作可靠性，实现日常运用的免维护。
（9）旅客界面。旅客界面设计坚持以人为本，运用人机工程学合理设计旅客乘坐空间、占用空间、通过空间和乘降空间。按照旅客旅行生理需求、卫生需求、休闲娱乐需求，合理分配资源，统筹安排饮水、卫生、集便排污、空调和旅客信息与影音系统设计，其中空调系统将充分考虑免受各种高速运行工况下车外压力波的影响。通过合理的旅客界面设计，最大限度保证旅客的乘坐舒适性，缓解旅途疲劳。

Standardised bogie

Standardised secondary suspension

@IR-TR @ahtan_china I could see them just now, but can't now.

 

[IR-TR]

Good I see them now. I like the one who came out first (with the gold colouring) better. Good to see CRRC standardized the intestines of the trains, saves a lot of time, money and resources. Gotta say though, the CRH380A is still the most purdy

 

[AndrewJin]

Impressive it's like you are commisioning a new line everyday

Only a 800km 350km/h line, a 300km 300km/h line and a 80km 200km/h intercity line were launched before July, perhaps the least productive 6 months so far.
