Advanced Technology: CRCC switches adopt multiple advanced technologies, such as inductive heating, integral molds, and automatic material conveying technology, achieving the only domestic process of one-time heating and continuous three-time forming. The full-fiber forging process is also used to break through the limitation of the original pressing process on the forging section length, producing switch points with a heel forging section length extended to 1,200 mm.
High Safety: For example, the 60E1 rail No. 16 single turnout innovatively adopts a new type of elastic fastener system and anti-theft fasteners. At the same time, the 9-meter ultra-long welded high-manganese steel integral cast frog can effectively improve the strength and wear resistance of the frog, ensuring the safe operation of trains.
Strong Durability: Through optimized design and selection of high-quality materials, CRCC switches can withstand long-term碾压 (rolling) and impact of trains, reducing the frequency of maintenance and replacement, extending the service life of switches, and lowering the total life-cycle maintenance cost.
Wide Application Range: The product series are comprehensive, covering high-speed, ordinary-speed, and speed-up turnout product series, as well as high-manganese steel and alloy steel frog product series, which can be widely used in various railway lines, stations, urban rail transit lines, etc.
Application Cases
Shanghai-Hangzhou High-Speed Railway: 54 sets of ballastless high-speed switches of CRCC were applied throughout the line.
Beijing-Shanghai High-Speed Railway: CRCC provided 19 sets of high-speed switches and 414 sets of ordinary-speed switches.
Chengdu-Pujiang Railway: Since 2015, CRCC has cumulatively supplied 45 sets of high-speed switches for the entire line.
Beijing-Xiongan High-Speed Railway: CRCC provided 68 sets of high-speed switches for the entire line, among which the switches at Daxing Airport Station contributed to the air-rail intermodal transportation construction of Daxing Airport.
Ganzhou-Shenzhen High-Speed Railway: All 120 sets of high-speed switches in the Guangdong section were supplied by CRCC.
Jinan-Zhengzhou High-Speed Railway: All 73 sets of high-speed switches in the Puyang-Zhengzhou section were provided by CRCC.
New Chengdu-Kunming Railway: CRCC supplied 340 sets of various switches for it.
Overseas Markets
Nigeria: In 2025, CRCC undertook the task of supplying 162 sets of switches for the entire Kamah Railway in Nigeria. On May 6, 20 sets of European-standard switches have arrived at Lianyungang, Jiangsu, and will soon be shipped to Nigeria. The shipped 60E1 rail No. 16 single turnout is a new product developed and customized strictly in accordance with European standards and customer requirements.
Significance of R&D and Innovation
Breaking Foreign Monopoly: High-speed switches were once long-term monopolized by foreign countries. The R&D and innovation of switch technology by CRCC and other enterprises have broken foreign technical barriers, enabling China to have independent intellectual property rights in the field of high-speed switches and reducing dependence on foreign products.
Promoting Railway Construction Development: Advanced CRCC switches provide high-quality key equipment for China's railway construction, ensuring the safe and efficient operation of railway lines and promoting the rapid development of China's railway cause in various fields, including high-speed railways, ordinary-speed railways, heavy-haul railways, and urban rail transit.
Enhancing International Competitiveness: With continuous improvement in technical level and product quality, CRCC switches have gradually gained recognition in the international market, helping to enhance the international competitiveness of China's railway equipment manufacturing industry, promoting Chinese railway technology and equipment to go global, and providing strong support for international railway infrastructure construction cooperation under the "Belt and Road" initiative.
