Purpose. The article proposes a technical solution to the design of the root-fastening assembly of turnouts, which corresponds to the operating conditions of the railways. Methodology. To achieve the stated goal, the authors analyzed the existing designs of root binding of turnouts and formulated proposals that should be used when developing new technical solutions for root binding. The designs of root bonds should provide simplicity of construction, have a few number of parts, be repairable; allow to use of special devices for the mechanization of installation and dismantling works, have a few cost, provide high reliability. It must also to provide high accuracy along the width of the path. Structures should be able to control the width of the path to the standard indicators in the lateral direction, and if necessary (in a straight line). The designs of root bonds should be adapted for all climatic conditions of Ukraine. Findings. Proposals have been used in the development and improvement of technical solutions for root bonding. A root binding was developed which was called the root binding of the insert-nodule type P and an improved root binding was developed, the improved design was called the root binding of the insert-nodular type SD. The developed technical solutions for the design of root bonds meet the requirements, and with the current content of the switch, they solve the problem of the need to adjust the width of the path in the knit root node. Originality. It has been established that the technical solution of root fastening of the insert-overlay type of CD has advantages over the technical solution of root fastening of the insert-overlay type P since it has the ability to move the root of the wit by changing the position of the regulating element to the field side, thereby facilitating the current maintenance of the path. Practical value. Proposals were developed for regulating the width of the path using the regulating element of the root fastening of the liner-overlay type of CD, the proposals took into account the requirements for different operating conditions, namely for the main, receiving and other routes taking into account the corresponding tolerances for them, the corresponding schemes of the control plates are given.
