Steel rails contribute to train braking efficiency in several ways. Firstly, steel rails provide a smooth and durable surface for the train wheels to roll on, ensuring minimal friction and allowing the wheels to maintain a consistent grip on the tracks during braking. This helps to prevent wheel slippage and allows for effective application of braking force. Additionally, the strength and stability of steel rails enable them to withstand the immense forces exerted by the braking system, ensuring reliable and efficient stopping of the train. Moreover, steel rails are designed with specific profiles and shapes that facilitate effective braking, such as providing a contact area that maximizes frictional forces between the wheels and the tracks. Overall, steel rails play a crucial role in maintaining the safety and efficiency of train braking systems.
