Abstract
The article presents a brief and comparative overview of the technical and operational rail lines used in the Baku Metro. The principles of schemes and rules for fixing rail lines on wooden sleepers and on concrete foundations, as well as their advantages and disadvantages, are described. It is established that relative to the construction with "metro" type fasteners, the path on the concrete structure is characterized by a low intensity of deviations. It is also shown that the main defects of the it stops alow structure can be associated, firstly, with the lack of restriction of the vertical degree of freedom of the rail (terminals), as a result of which the contact points of the fastening elements experience increased wear, and secondly, with rotting, shrinkage and deformation of wooden sleepers. All the described defects are massive in nature and lead to a large number of deviations in the current content of the GRK, including deviations that require limiting the speed of trains.
