The maximum speed that steel rails can handle depends on various factors such as the quality of the rail material, maintenance practices, and the design of the track. Generally, steel rails can handle speeds ranging from 80 to 125 miles per hour (130 to 200 kilometers per hour) for conventional rail lines. However, for high-speed rail systems, specially designed tracks and rails can support speeds of up to 186 miles per hour (300 kilometers per hour) or even higher.
