| Abstract: | The optimization of unequal length easement curve with or withoutcontrolling points in reconstructing existing railroads is discussed.A theoretical equation of radius for unequal length easement curvewith higher accuracy is proposed. Methods for providing the initialvalue and resolving the problem of relative deviation of control-ling points in the process of optimization are recommended. |

| Keywords: | existing railroads radius of curve easement curve direct optimization |
