<p>A method of profiling a railway crossing may include determining an angle of taper of a rail vehicle wheel; applying a raised weld section to a wheel contact surface of the railway crossover; and planing the raised weld section to correspond to the angle of taper in a single set-up pass across the length of the railway crossover creating a wheel matched profile. The railway crossover may be a rail frog or a diamond crossing. The method may also include creating a three-dimensional surface contour model of the crossover by replicating a standard crossover profile; creating a wheel profile model that matches a wheel profile for a rail vehicle of the railway; defining wheel contact surface for the rail vehicle by transposing the wheel profile model over the standard crossing surface contour model; and modeling a raised weld section to be placed along the wheel contact surface.</p> |
