A rail manufacturing method of performing forced cooling on at least a head of a rail that is hot after hot-rolled at an austenite region temperature or higher or after heated to the austenite region temperature or higher, wherein the rail has a chemical composition containing, in mass %, C (carbon) in a range of 0.70% or more and 0.85% or less, Si (silicon) in a range of 0.1% or more and 1.5% or less, Mn (manganese) in a range of 0.01% or more and 1.5% or less, P (phosphorus) in a range of 0.001% or more and 0.035% or less, S (sulfur) in a range of 0.0005% or more and 0.030% or less, Cr (chromium) in a range of 0.1% or more and 2.0% or less, optionally at least one selected from Cu (copper) in a range of 1.0% or less, Ni (nickel) in a range of 0.5% or less, Mo (molybdenum) in a range of 0.5% or less, V (vanadium) in a range of 0.15% or less, and Nb (niobium) in a range of 0.030% or less, optionally at least one selected from Ca (calcium) in a range of 0.0005% to 0.010% and REM (rear-earth metals) in a range of 0.005% to 0.1%, and the balance being Fe (iron) and unavoidable impurities, the rail manufacturing method comprising: performing the forced cooling for 10 seconds from start of the forced cooling so that a cooling rate at a surface of the head becomes 1°C/s to 20°C/s; performing the forced cooling during a period after a lapse of 10 seconds from the start of the forced cooling until heat generation during transformation begins at the surface of the head so that the cooling rate at the surface of the head becomes 1°C/s to 5°C/s; performing the forced cooling during transformation from beginning to end of the heat generation during transformation so that the cooling rate at the surface of the head becomes lower than 1°C/s or a temperature-rising rate becomes 5°C/s or lower; and performing the forced cooling during a period after the end of the heat generation during transformation until temperature at the surface of the head becomes 450°C or lower so that the cooling rate at the surface of the head becomes 1°C/s to 20°C/s. C (carbon) in a range of 0.70% or more and 0.85% or less, Si (silicon) in a range of 0.1% or more and 1.5% or less, Mn (manganese) in a range of 0.01% or more and 1.5% or less, P (phosphorus) in a range of 0.001% or more and 0.035% or less, S (sulfur) in a range of 0.0005% or more and 0.030% or less, Cr (chromium) in a range of 0.1% or more and 2.0% or less, optionally at least one selected from Cu (copper) in a range of 1.0% or less, Ni (nickel) in a range of 0.5% or less, Mo (molybdenum) in a range of 0.5% or less, V (vanadium) in a range of 0.15% or less, and Nb (niobium) in a range of 0.030% or less, optionally at least one selected from Ca (calcium) in a range of 0.0005% to 0.010% and REM (rear-earth metals) in a range of 0.005% to 0.1%, and the balance being Fe (iron) and unavoidable impurities, performing the forced cooling for 10 seconds from start of the forced cooling so that a cooling rate at a surface of the head becomes 1°C/s to 20°C/s; performing the forced cooling during a period after a lapse of 10 seconds from the start of the forced cooling until heat generation during transformation begins at the surface of the head so that the cooling rate at the surface of the head becomes 1°C/s to 5°C/s; performing the forced cooling during transformation from beginning to end of the heat generation during transformation so that the cooling rate at the surface of the head becomes lower than 1°C/s or a temperature-rising rate becomes 5°C/s or lower; and performing the forced cooling during a period after the end of the heat generation during transformation until temperature at the surface of the head becomes 450°C or lower so that the cooling rate at the surface of the head becomes 1°C/s to 20°C/s.
