Provided is a pearlite rail containing, by mass, 0.65-1.20% carbon, 0.05-2.00% silicon, and 0.05-2.00% manganese, with the remainder containing iron and unavoidable impurities. At least part of the head and at least part of the base of the provided rail are pearlite. The aforementioned pearlite regions have a surface hardness between 320 and 500 HV and a maximum surface roughness of at most 180 µm.
