The pressure plate assembly is a component of railway lines, and the track referred to here includes many components. As a holistic engineering structure, the track is laid on the roadbed, playing a guiding role in train operation and directly bearing the enormous pressure of locomotives, vehicles, 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 at the specified high speed. In the annual procurement of railway vehicles by the Ministry of Railways, in addition to the demand for new vehicles brought about by the increase in mileage, a large part of the demand for vehicle updates and replacements is also included. Railway pressure plates have developed rapidly in recent years. Against the backdrop of increased speed and heavy loads, in order to achieve the goal of hundreds of kilometers per hour or heavy loads of tens of tons or more, it is necessary to equip railway pressure plates that meet the needs of high-speed heavy loads, are safe, reliable, and of high quality. This will directly accelerate the demand for vehicle parts with high technological content, and there will be great development space for the new generation of products and technologies. 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. Railway accessories are components of railway lines, including rails, sleepers, connecting parts, trackbeds, anti climbing equipment, rail supports, and turnouts.
