The article addresses the issue of designing the geometry of a curved double track using the analytical design method principles. This allowed, similarly to other applications of the method, a complete overview of the issue and the method for determining the key parameters to be defined. The analytical method for determining the intertrack space axis and the outer and inner track axes is introduced, leading to the required value of the intertrack space widening. The widening is achieved by varying the length of the transition curves in the outer and inner tracks. With the track axis coordinates in the local coordinate system, these can be easily transferred to the PL-2000 two-dimensional Cartesian coordinate system, i.e., an element of the national spatial reference system. The analysis continues with the issue of the chainage of axes of the intertrack space and the mainline tracks. The applicability of the proposed method and its high precision are demonstrated by examining a wide radius range of circular curves.
