Overview of the Development of Electric Traction Technology for Urban Rail Transit Vehicles
The birth of rail transit vehicles is based on the technical innovation of the steam engine and the official emergence of the railway. Its traction technology has gradually realized the transition and transformation from the steam engine to the internal combustion engine and then to the electric power. At present, the electric traction technology has become the core technology of urban rail transit vehicles.

Traction system: Era Electric is in a leading position
The electric traction transmission system is the power source of high-speed trains, equivalent to the "heart" of high-speed trains. Due to relatively high market barriers, the market was primarily occupied by domestic joint ventures of foreign companies such as Siemens and Alstom in the early stages.
New market size of up to 3 trillion yuan, urban rail transit industry chain enterprises welcome more opportunities
As early as the 2008 economic crisis, the government spent huge amounts of money to increase the construction of major infrastructure such as railways and highways. Rail transit investment was an important lever to hedge against economic decline. Faced with the current economic difficulties, the government has once again increased the construction of rail transit, and at this time, the rail transit sector deserves special attention.
Breaking through key technologies and entering the high-speed track through urban rail construction
Urban rail transit has a huge impact on promoting urban structural adjustment, urban layout integration, land development and utilization, as well as the sustainable development of cities and transportation. The picture shows the underground space complex of Wuhan Optics Valley Square planned and constructed by China Railway Fourth Engineering Group Corporation.

Liyang Enterprises Break the "Bottleneck" of Traction Technology and Solve the "Stuck Neck" Dilemma
In key fields and industries such as information and communication, high-end equipment, industrial basic materials, and aerospace, there are some technological shortcomings in China. Solving the shortcomings is a hurdle that must be overcome to accelerate the construction of technology enterprises. The Liyang Generalized Traction Technology Research Institute has solved the bottleneck constraints of key core technologies for locomotive traction through independent innovation, and improved the market competitiveness of its products.
