A railway wheel is a crucial component of a train, designed to support the weight of the train and facilitate smooth movement along the tracks. Typically made of steel, these wheels are shaped in a way that allows them to fit securely on the railway tracks, ensuring stability and safety during travel. The design of railway wheels includes a tapered profile, which helps in guiding the train along curves and reduces wear on both the wheels and the tracks. Proper maintenance of railway wheels is essential for the overall performance and longevity of the train system.
