Assumed that the transition curves are subject to certain dependencies curvature and torsion (for space curves) on the arc length and match the criteria of designing railway. Geometric modeling transition curves railways performed using curves obey the third and fourth degrees of curvature distribution along the arc of a circle for flat transition curves and quadratic distribution of the curvature and torsion - for space curves. Problems of modeling transition curves for existing sections of track, when the location of the center of the straight and circular sections should remain unchanged, transition curves with the restriction on the location of the circular section of the plane, the spatial transition curves connecting two straight or two circular section of track, located in parallel planes. Spatial transition curves can be modeled with a zero or a given deviation from the tangent plane at the endpoint. On the basis of the proposed approaches to geometric modeling of railway track transition curves appropriate software to object-oriented programming language Object Pascal in the visual programming environment Delphi, which can be used in the design, the construction of new and modernization of existing sites railway.
