As the "brain and central nervous system" of high-speed rail, train control technology for high-speed rail has long been monopolized by very few multinational companies. It was not until the C3-class train control system independently developed by China came out that China's high-speed railways really got rid of the unfavorable situation of long-term control.
Under the escort of this train control system, my country's high-speed rail operation density has reached the highest in the world, making it one of the safest countries in the world for railway operations. At the same time, the system can fundamentally guarantee the safety of my country's railway construction and transportation, and provide core technical support for the construction of the "Belt and Road" and the "going out" of high-speed rail.

"In the early stage of China's high-speed railway construction, China Railway Communication and Signal Group Corporation (hereinafter referred to as "CRSC") quickly gathered a high-end R&D team of more than 3,000 people in the whole system to form the high-speed railway C3 train control system, subway CBTC train control system, etc. Independent research team. We adhere to the technological path of introducing, digesting, absorbing and re-innovating. After 3 years of hard work, we have finally realized the complete autonomy of my country's high-speed rail and subway train control system technology and 100% localization of products, and completed the five major rail transit projects. A major breakthrough in core independent technology." Zhou Zhiliang, chairman of CRSC, said, "The real core technology cannot be introduced, and it has to be done."
In the world's largest comprehensive experimental hall of train operation control system of CRSC, you can really feel the power of the C3-class train control system. "This C3-class train control system with completely independent intellectual property rights is at the world's leading level and can meet the operational requirements of a maximum operating speed of 350 kilometers per hour and a minimum tracking interval of 3 minutes." said the staff of CRSC Research and Design Institute. The system is developed on the basis of absorbing and inheriting a large amount of operating experience of existing systems, according to China's train control standards and facing future development needs. Its biggest advantage is not only 100% localization, but also the interconnection with the European ETCS-2 system.
Turning crisis into opportunity
"After the '7.23' accident in 2011, CRSC took a back-to-back battle and adopted a variety of reform measures, and the company has embarked on a rapid development track from the crisis." Zhou Zhiliang said, "After years of development, CRSC has successfully stepped out Quality and safety crisis, product crisis, business stagnation crisis, financial crisis, and brain drain crisis have developed from a severely hit central enterprise into a leader in the world's rail transit control system industry that has greatly improved its independent innovation capabilities and ranks first in the industry."
Breaking the boat and turning crises into opportunities depends on the full flowering of reforms.
First of all, in terms of quality and safety, CRSC strives to improve service levels through the construction of multi-dimensional long-term mechanisms such as technology, equipment, talents, and management. The number of high-speed rail quality and safety accidents has decreased year by year, and production safety accidents of general category B and above have been eliminated. "After more than five years of development, my country's railway construction has basically achieved a transition from a high accident failure rate to a stable, safe and reliable operation, which has effectively guaranteed the safety level of my country's high-speed rail operations and established the world's confidence in China's high-speed rail operation level, core technologies and equipment. "Zhou Zhiliang said, "Under the escort of the train control system, my country's high-speed railway operation density has reached the highest in the world, and it has become one of the safest countries in the world for railway operation.
Secondly, in terms of products, by vigorously promoting independent technological research and implementing intelligent manufacturing, CRSC has built a world-class comprehensive laboratory for simulation, inspection, testing and testing, transforming and upgrading from a traditional signal industry enterprise to a digital, intelligent and networked enterprise. modern factory. At the same time, through means of international authoritative certification, third-party safety assessment and certification of security-related products, and real-name information management of the whole life cycle, CRSC has achieved world-class quality and the strength to compete with world giants.
In 2015, CRSC was successfully listed in Hong Kong. "At present, the entire group has light assets, low debt, and a healthy and stable financial position. After years of reform, the group has not only attracted high-end technical talents from the society to join in, but also many key talents who were lost in the past have also returned." Zhou Zhiliang said.
Statistics show that CRSC now has a world-class technology research and development team with a scale of more than 3,800 people, including nearly 2,000 masters and doctors. During the "Twelfth Five-Year Plan" period, various economic indicators of CRSC maintained an ultra-high growth rate of over 20%. Among them, the total assets in 2016 were 3.3 times that of 2012, and the net assets were 3.7 times that of 2012.
New target of intelligent high-speed rail
"The successful research and development of the C3-class train control system can fundamentally guarantee the safety of national railway construction and transportation, and provide core technical support for the 'Belt and Road' construction and the 'going out' of high-speed rail." Zhou Zhiliang said, as China's high-speed rail "going out" An important member of the alliance, CRSC is currently participating in the construction of Jakarta-Bandung high-speed rail in Indonesia, the Orange Line in Lahore in Pakistan, and railway freight transformation in India. "CRSC will strive to promote the "going out" of China's high-speed rail and a full set of technical standards, and show the world the beautiful national business card of "China's high-speed rail"."
In addition, while expanding the core communication and signal business, CRSC is also making efforts in the fields of electric power electrification business, communication information business, tram vehicle and train control system, focusing on intelligent manufacturing, and striving to build integrated rail transportation. system.
"The high-speed rail in the future will be smarter and simpler." Zhang Zhihui, chief engineer of CRSC, said that networking, simplification and modularization will become the three symbols of intelligent high-speed rail. With the continuous advancement of the "Belt and Road" construction and "Made in China 2025", China's high-speed rail and related technologies and standards will surely appear on the world stage with a new look, playing the strongest voice from China!
