Phantom of the 7.23 accident - high-speed rail supplier

In addition to the 32 high-speed rail concept listed companies, there are still many shadow companies that have not entered the public eye. "There are specific company-related bidding catalogues, but we haven't seen them yet."

Until the first victim’s compensation was reached, the cause of the accident was still the mystery of the 7.23 甬 temperature train rear-end accident.

On July 24, Zhang Dejiang, vice premier of the State Council, went to Wenzhou to direct accident rescue, aftermath handling and investigation, and announced the establishment of an accident investigation team of the State Council. This survey group consists of various experts from the Ministry of Railways and the State Administration of Work Safety.

At this time, the "black box" of two crashed cars (the "Railway Signal Microcomputer Monitoring System", which records the operation of the station staff on the console throughout the day) has been found.

On July 27, Premier Wen Jiabao of the State Council presided over a State Council executive meeting and expressed deep condolences to the victims of the special railway traffic accident on July 28, 2002. The meeting requested that “the investigation and handling work should be open and transparent, and the results be announced to the people and to the people. The masses are accountable sincerely and responsibly."

On July 28, An Lusheng, director of the Shanghai Railway Bureau, said: According to the preliminary analysis of the situation, the accident was "due to the serious design flaws in the signal equipment of Wenzhou South Railway Station. After a lightning strike failure, it should have been displayed as a red light. The semaphore error of the zone is displayed as a green light." "The signal device with design defects was designed by a research and design institute in Beijing and put into use on September 28, 2009."

The trains used in this accident were CTCS-2 (D301) and CTCS-3 (D3115) train control systems. Both trains are equipped with ATP (train automatic protection system) and LKJ (train monitoring and recording device for trains), which are two kinds of trains overspeed protection equipment. They can automatically decelerate or even stop the train in an emergency, plus manual scheduling. Triple insurance, why does the D301 still not stop the car?

The train control system consists of a series of complex subsystems. Outside the system general contractor, each subsystem and device has a different supplier.

"Shadow Company"

“At present, China’s high-speed railway has formed its own complete set of technical standards in terms of engineering construction, high-speed trains, train control, passenger station construction, system integration, operation and maintenance, and environmental protection standards.” Chief Engineer of the Ministry of Railways, Chief Designer of High-speed Railway He Huawu once said.

Behind these dazzling technologies, many companies are surrounded.

At present, among the listed companies in Shanghai and Shenzhen, a total of 32 listed companies are high-speed rail stocks. Including the Ministry of Railways subordinate enterprises, such as China Railway, China Railway Second Bureau; there are also SASAC's China South Locomotive, China North Car, etc.; there are some private enterprises, such as Century Real, brilliant technology.

Among the unlisted companies, there are also China Railway Communication Signal Group (hereinafter referred to as Tonghao Group), Casco, Hollysys, etc. as CTCS train control system companies.

Among the above-mentioned companies, a large number are suppliers involved in the rear-end collision accident at the Wenzhou line.

The first is the Tonghao Group. As a state-owned enterprise under the SASAC, the Tonghao Group is the general contractor for the "four-power" system integration project of Yongtaiwen. The signal system products of the Tonghao Group include automatic blocking systems, computer interlocking systems, train dispatching and commanding systems (TDCS), dispatching centralized systems (CTC), localized automatic train protection ATP systems, station train control centers and transponder systems, and humps Automatic control systems, turnout conversion security systems, etc.

One of the most proud of these is the CTTS-3 train control system developed for high-speed railways that fully realizes independent intellectual property rights. Since December 2009, it has been widely used in China's high-speed rail.

CTTS-3's R&D was mainly completed by the research and design institute under the Tonghao Group, which has been renamed as Beijing Quanlu Communication Signal Research and Design Institute. The ZPW-2000A non-insulated frequency-shifting automatic blocking system used in the Yongtai-Wenzhou line is the proud work of the Institute's independent research and development design. It has won several awards for scientific and technological advancement from the State and the Ministry of Railways.

The Ningbo-Taiwan-Wenzhou Special Line CTC System Project is under the responsibility of Casco Signal Co., Ltd., which was jointly funded by Tongtong Group and Alstom Investment Co., Ltd.

In addition, another well-known automation control system platform provider in the industry and Lishi Company have also admitted that they provided a CTCS-2 on-board train control system for a broken car. Hollysys, formerly known as the sixth institute of the Ministry of Electronics (Automation Division), is currently the main provider of train control systems for high-speed rail in China. At present, more than 400 ATPs have been successfully used in 9 bureaus (Beijing Bureau, Shanghai Bureau, Guangzhou Railway Group, Chengdu Bureau, Zhengzhou Bureau, Wuhan Bureau, Nanchang Bureau, Jinan Bureau, Xi'an Bureau). ).

"After the introduction of Japan's train control system technology in the Ministry of Railways, we designated the Tonghaoyuan and Helishi to take charge of the introduction, digestion, and absorption, and to form products with independent intellectual property rights. These are led by enterprises, and other research institutes are not involved in deep. "An expert from China Academy of Railway Sciences told this reporter.

Among the private enterprises, there are many system providers in the Taiwan-Taiwan-Wenzhou line: the "Railway Signal Microcomputer Monitoring System" of Shengli Technology, the "Railway Communication Monitoring System" and "Railway Integrated Video Surveillance System" of Century Riel, and Newsflash's "dispatch communication system" and "emergency rescue command communication system". Dinghan Technology, Tracht, Yuanwang Valley and other companies also share a share in the high-speed rail industry chain.

In addition, there are many shadow companies that have not entered the public eye. "There are specific company-related bidding catalogues, but we haven't seen them yet," a manager of the Institute of Iron and Steel Sciences told the reporter.

The train sounded gold

Concurrently with China’s high-speed rail leap is hundreds of billions of investment each year, the Ministry of Railways’ giant greed, Liu Zhijun, and Zhang Shuguang, as well as high debt.

Many of the high-speed rail suppliers that have already been exposed are inextricably linked to the railway sector.

In private enterprises, the origins of the Ministry of Railways seem to be even more important, and the executives who can get high-speed trains are also coming from behind.

The huge benefits that high-speed rail brings to these companies are obvious.

Take China South Locomotive as an example, its subsidiary Qingdao Sifang Bombardier (a joint venture between CSR Sifang and Bombardier) is the main manufacturer of EMUs. China South Locomotive 2010 annual report shows that in 2010 the company achieved operating income of 64.9 billion yuan, an increase of nearly 40%. In terms of classified products, the company’s rapid income growth in 2010 mainly lies in the sales revenue of EMUs and urban rail vehicles.

According to the 2010 Annual Report of Glory Technology, the company’s railway communications and signal industry generated revenue of 244 million yuan, accounting for 98% of the main business income.

Jiaxun Feihong is more dependent on the railway market. Its three major product categories and all its revenues come from the railway market. Century Riel is also the same.

After the rear-end tragedy, the listed company’s stock price plummeted. From July 24 onwards, the high-speed rail stocks represented by China South Locomotive and China North Locomotive fell 15.11% and 13.38% respectively in two trading days, and some stocks once fell to a stop.

Therefore, despite the fact that the black box of the accident is still being analyzed, all equipment suppliers, especially listed companies, have come out of trouble with the accident.

Century Riel issued a “clarification announcement” stating that the “railway communication monitoring system” provided for the Yongtaiwen Passenger Dedicated Line mainly monitors the operation of equipment in railway communication rooms.

However, investors in the investment community questioned that this is inconsistent with the function description of the system in the prospectus, “Remote control of railway communication equipment and lines (optical fiber), etc., and monitoring of safe operation of equipment”.

In addition, in the “Clarification Announcement”, the expression “Railway Integrated Video Surveillance System” provided by Century Riel for the Ningbo-Taiwan-Wan passenger dedicated line is also different from the prospectus. One is “to provide video surveillance services for the railway sector” and the other It is “intuitive observation of all types of facilities and equipment along the railway line and confirmation of safety status. Using video recognition technology, it monitors and manages the safe operation of equipment and facilities along the railway and realizes early warning”.

Another company's brilliant technology clarified after the accident that "the company only has one product for the relevant road sections, namely the centralized railway signal monitoring system, which is an important vehicle equipment for ensuring the safety of the traffic in the station and strengthening the management of the signal equipment joint department. It is called electricity. The black box of the service system, and "the system is operating normally." Then was also questioned as "sweep concept."

Jiaxun Feihong and Teruid also said that the products they provided were operating normally.

As of July 27, all personnel from Qingdao Bombardier and Tongyuan Hospital had responded to the “Oriental Outlook Weekly” that high-level company officials had rushed to the scene to participate in the accident investigation and could not provide further information.
