FIELD: repairs and maintenances of railroad jointless track. SUBSTANCE: rail length real tensions at moment of dressing operation realization are determined, for example, according to rails temperature change since moment of their fixation on under rails base. Before dressing of separate subsections rail length of two subsections length, that are to be dressed in direction from curvature center is heated up to temperature, for example, of +25 C. As a result of it within length of the subsections in rail length appear pressing tensions. Then ballast at ends of sleepers, that are located in direction of dressing of separate subsections, is made loose and the subsections are dressed in required directions by required value, that is determined preliminary. EFFECT: improved process.
