July 28 , the newly appointed Secretary of the Shanghai Railway Bureau , said An Lusheng , according to a preliminary understanding of the situation analysis, " 7-23 " motor car accident was due to the Wenzhou South Station signal equipment there are serious flaws in the design, failure after being struck by lightning , resulting in the range should be displayed as a red light error signal is displayed as green. Meanwhile, dispatchers did not discover . Specific findings of the joint investigation team needs to publish . An Lusheng said that a design flaw in signaling equipment designed by a Beijing Research and Design Institute , September 28, 2009 and put into use .

Even if the signal equipment failure , with trains running surveillance recording device (LKJ) and automatic protection system (ATP) " double insurance" motor car , close, it should automatically brake the car off in the distance , even if the "double insurance" are invalid, there should also be monitored manually scheduling ; even artificial scheduling also fail, " fail-safe oriented principles " will command two EMU immediately stopped . However , the reality is bypassing all the " obstruction factor " so that two EMU "magic" to rear-end .

Cause of the accident has been initially identified , but the high- speed railway construction to re- think and positioning will continue to extend . High-speed rail really safe? Is it because the pursuit of construction speed while ignoring the very small but can be fatal to those details ? Whether the future will thus slowing construction ? From the capital market perspective, the industry 's boom and the company's valuation model that should re-examine ? This brings the industry suffered a sudden surprise hit but also has much investment value ?

In the Chinese Academy of Engineering, Beijing Jiaotong University professor Wang Meng-shu view, the current status quo of China's railway is facing the need to keep up the level of integrated management of railway development . Rail transport is a shortage of talent , but the treatment is relatively low railway workers , the railway sector is difficult to retain qualified personnel ; Moreover, the existing Ministry of Railways , Railway Bureau, the three-tier management system management station segment could easily lead to excessive concentration , leading to manage difficult place .

Li Xiaoguang SW industry analysts believe that the major effects of the accident , the Ministry of Railways to work or will be transferred , the Ministry of Railways is expected to carry out the full range of road safety inspections , and investors expect the Ministry of Railways reform , massive bidding progress of work and planning new lines may be delayed .

Tai Asset Management Chief Investment Officer of Shenzhen Wang Liang is very pessimistic. He believes that high-speed rail investment growth in related industries will be greatly reduced or even negative growth. High-speed rail will slow down , stop and continue the transformation , modification planning , the industry would be devastating , long-term stock price will fall . " Highly dependent on the construction of high-speed rail industry segments listed companies , even if their valuation levels fall to 10 times earnings, do not have the investment value. Actual business impact of the incident on the company is substantial , after the high-speed rail drop speed itself is a clear signal that is safety first , and now Wenzhou motor car accident , high-speed rail construction will be more cautious , the demand for relevant signals and other accessories listed company's products will correspond to slow down and reduce .

" It is understood that the accident due to the EMU was struck by lightning , causing loss of power parking two cars rear-end ." National Grid said .

Earlier, the "loss of power" is understood as repeated power outages, network microblogging even think MOR expression is shirking their responsibilities , " frame " supply side .

National Grid who also introduced , EMU is used to run the railway catenary, independent of the State Grid Corporation of the grid , the railway sector is responsible for operation and maintenance . Although still the national power grid , but because this part of the assets belonging to the user , the national grid and the railway catenary on the management and operation is not related .
