Bro, your Chinese is a little dramatic to me.

His Chinese is too much Google translate for me

"他的中國實在是太多了谷歌翻譯我" <--makes no sense

These words scared me a little.

太好了！太好了！

There should be assistant driver for help.

it's quite arguable there should be an assistant driver or not.
The case in most EMUs in China is no.
When the driver has a heart attack, then he cannot touch an alarm device which requires the driver touch it like every half a minute, then the train will automatically stop.

I wonder if this is what happened on this high speed train; not that the driver had heart attack but just didn't touch off the alarm safety in time.

The alarm goes off at 1 minutes then it goes off a bit after that.

@Tom99 Gosh, this driver would face a big blow to his face. Every detail of his driving was recorded and would be checked everyday! If he didn't respond to overspeeding alarm within one minute, the EMUs would stop and other stuff on the train could also press the emergency button.

Wish what the driver had received was just a warning and penalty.

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。

TOO TECHNICAL?
For ordinary passengers, it means the new types will be much more comfortable!
2nd class=1020mm(40.15 inches)
1st class=1160mm(45.67 inches)
Say goodbye to airplane economy class!!!
(most economy seat=31-31 inches, at most 33-35 inches)

Can you post in English too

@Echo_419
No English yet, too many technical words which are beyond me.
Basically, every component is modular and energy-saving.

For ordinary people, it's simple, better interior design, more comfortable.
