abstract="In the present paper a static analysis of a straight CWR track's stability in vertical plane under the occurrence of high rail temperatures is considered. The target of investigation is to properly answer a question of a possible local stability loss in vertical plane on an originally straight CWR track of infinite length, resting as a weighty beam on horizontal substrate, due to an action of large compressive forces from rail temperature changes and an external impulse. A typical form of spontaneous hogging track is a single wave shape. The following analysis could state if for contact loss between railway track and subgrade an &quot;external interference&quot; i.e. external lifting force is necessary. Shown in the paper is an influence of railway track weight and roadbed curvature on stability condition of railway in vertical plane. The results of a theoretical analysis carried out on CWR track stability scale in vertical plane, regarding an influence of real factors disturbing its behaviour on site, are a basis for determination of its safety conditions in service. For such analysis especially formula (3.6) and Section 3 are of a basic importance. The obtained results have an essential value in problem of vertical plane analysis of a CWR track in service.<p />",
