What material are railway tracks made of?
What material are railway tracks made of?
hot-rolled steel

Which type of welding is used in railway tracks?
The principle of aluminothermic welding is based on an exothermic chemical reaction of aluminium powder and iron oxide, producing sufficient heat to cause melting. Before melting can start, the ends of the rails are cut to create a specified gap and the rails are aligned.
Why steel is used in railway lines?
