The disclosure relates to heavy-masse railway rails in which an increased fatigue resistance is achieved by increasing the moment of inertia of cross-section of rail and by increasing the ratio of fatigue loading, a sub-unity ratio given by the specific moments of fatigue of the two portions of cross-section of rail defined by the horizontal neutral axis of cross-section of rail, or by the squares of normal unity fatigue stresses, which are maximum at the two vertical extremities of cross- section of rail.
