A web search for rail road rails reveals a type of steel known as Pearlitic steel

According to US patent number 6375763, this type of steel has better wear resistance than previously used pearlitic steel rail and sufficient ductility to prevent cracks due to thermal expansion and contraction caused by changes of temperature.

For building rial roads the steel must be of good quality and it must sustain in a very high temperature.
