Welded rail

A welded rail comprising:

• a plurality of rail portions;
• and
• a welded joint portion which joins the rail portion, wherein
• the rail portion contains, as a chemical composition, in a unit mass %,
• 0.85 to 1.20% of C,
• 0.10 to 2.00% of Si,
• 0.10 to 2.00% of Mn,
• 0.10 to 1.50% of Cr,
• 0.0250% or less of P,
• 0.0250% or less of S,
• 0 to 0.50% of Mo,
• 0 to 1.00% of Co,
• 0 to 0.0050% of B,
• 0 to 1.00% of Cu,
• 0 to 1.00% of Ni,
• 0 to 0.20% of V,
• 0 to 0.0500% of Nb,
• 0 to 0.0500% of Ti,
• 0 to 0.0200% Mg,
• 0 to 0.0200% Ca,
• 0 to 0.0500% of REM,
• 0 to 0.0200% of N,
• 0 to 0.0200% of Zr, and
• 0 to 1.000% of Al,
• the remainder includes Fe and impurities,
• in a cross section parallel to a longitudinal direction and a vertical direction of the welded rail and passing through a center of the welded rail in a width direction, a HAZ width (W), which is a distance between two most softened portions formed on both sides of a welding center of the welded joint portion measured along the longitudinal direction of the welded rail, is 60 mm or less, and
• an interval between the most softened portion and the welding center measured along the longitudinal direction in the cross section is defined as WX and a region where a distance from the welding center is 0.6 WX to 0.7 WX and a depth from a top portion outer surface is 2 to 5 mm is defined as a pro-eutectoid cementite structure evaluation region, and in the pro-eutectoid cementite structure evaluation region, a total number of intersections (N) of a pro-eutectoid cementite structure intersecting a cross line including two line segments having a length of 100 μm parallel to the longitudinal direction and the vertical direction is 26 or less.
