Abstract:
A profiled rail having a reduced radiated noise level when in use comprising a foot section with a top surface, a web section with a lateral web surface, a head section with a tread surface, a rail height, and a moment of inertia and a section modulus about an axis extending through the center of gravity of the rail whose values correspond substantially to those of a standard profiled rail having the same load-bearing capacity, the rail having a cross-sectional profile formed symmetrically to a height axis of the rail and a concavely rounded lower lateral surface area extending from the top surface of the foot section to an intersection between the lateral web surface and the axis extending through the center of gravity, the concavely rounded lower lateral surface area being free of angularities in the cross-sectional profile of the rail.
