Train Wheel Manufacturing and Functionality

The video tutorial explains the process of manufacturing train wheels and axles. It covers the melting of recycled steel, molding it into ingots, and cutting them into sections for wheel formation. The wheels undergo several shaping processes, including pressing and rolling, to achieve the desired size and specifications. The axles are forged and shaped to fit the wheels, followed by assembly and final quality checks. The entire process ensures that the wheels and axles are ready for installation under trains.
