Optimum Railway Transition Curves—Method of the Assessment and Results

This article discusses the optimization of railway transition curves, through application polynomials 9th and 11th degrees. In this work, authors use a 2-axle rail vehicle model combined with mathematically understood methods. is used to simulate movement negotiating both curve circular arc. Passenger comfort applied as criterion assess which actually best one. The 4-axle was also verify results obtained using vehicle. Our show that traditionally in engineering transition—3rd degree parabola—which not always optimum curve. fact especially valid for longest lengths greater than 150 m. For such cases, curves similar standard degrees ones. result confirmed by
