Railway tracks are banked on curves so that the required centripetal force can be obtained from the horizontal component of the train’s weight; option [C]. This prevents the train from derailing by providing the necessary inward force to counteract the outward force experienced during curved motion. It allows for safe and stable traversal of curves at higher speeds, as the banking angle is designed to match the curvature and speed of the trains. Option C correctly identifies this principle, highlighting the significance of utilizing the horizontal component of the train’s weight to maintain stability and prevent accidents on curved sections of railway tracks. This engineering technique optimizes safety and efficiency in railway transportation systems by ensuring that trains can navigate curves smoothly and securely, enhancing overall operational performance and passenger safety.
