Abstract (en)
[origin: WO9535413A1] The disclosure relates to heavy-mass railway rails wherein 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 halves 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.
