Railway accessories are an integral part of a railway line, and the track referred to here includes many components. As a comprehensive engineering structure, the track is laid on the roadbed, playing a guiding role in train operation, directly bearing the enormous pressure of locomotives and their loads.
Under the power of train operation, its various components must have sufficient strength and stability to ensure safe, smooth, and uninterrupted operation of the train according to the specified maximum speed. In the annual procurement of vehicles by the Ministry of Railways, in addition to the demand for new mileage, there is also a significant demand for vehicle upgrades. In recent years, railway accessories have developed rapidly. Against the backdrop of increasing speed and heavy loading of railway accessories, in order to achieve the goal of hundreds of kilometers per hour or dozens of tons or more of heavy loading, it is necessary to equip railway accessories that meet the needs of high-speed and heavy loading, are safe, reliable, and high-quality. This will directly accelerate the demand for high-tech vehicle accessories. The new generation of products and technologies will have great development space. Since the railway leap forward development plan was launched eight years ago, China's investment in railway construction has increased significantly. Seven years ago, the investment in railway infrastructure construction and the investment in the purchase of rolling stock doubled from five years ago. By six years ago, the national railway fixed assets investment had reached more than 200 billion yuan. More related products such as fishplates and spring bars.
