Why did the trains of China Railways High Speed (CRH) 和谐号动车 crash


A train collision occurred at about 8:30 pm Saturday (July 23, 2011) on a bridge near Wenzhou of China when bullet train D301 (modal CRH2-139E) rear-ran into D3115 (modal CRH1-046B), which allegedly lost power after lightning strike. It has killed 35 people and left 192 others injured, as a spokesman of the Ministry of China Railways said.

The accident exposed once again some officials of Chinese Government are used to being boastful rather than doing practical work. According to Baidu Wiki of China, there are five modals of bullet trains running in China high-speed railway networks: CRH1, CRH2, CRH3, CRH5, CRH380A. Their technologies were imported respectively from Canadian Bombardier, Japanese Kawasaki, German Siemens, and French Alstom.

The technologies of the accident-involved bullet trains D301 (modal CRH2) and D3115 (modal CRH1) stemmed from Japan and Canada respectively, although China has announced it has digested all of the core technologies of the five modals of high-speed trains and owned the intellectual properties of them.

With a mix of so many different technologies in the high-speed railways, the harmony of them in railway networks should be carefully dealt with and realized. The collision told us that some officials of China Railways did not obviously do a proper job on it. They pushed rashly a pre-mature thing out due to some officials’ exaggeration for being promoted.

Because the collision happened in the area of China Shanghai Railway Bureau, the top officials of the bureau were dismissed immediately. From the feature of the accident it seams unfair that they were blamed for this disaster. At least they were not the only who should be blamed.

China is actively promoting its technologies of High Speed railways to the world. The accident affected inevitably China’s effort, although the spokesman of the Ministry of China Railways said, "China's high-speed train is advanced and qualified. We have confidence in it.”
