Abstract
Maintenance of track and switches of differs significantly from main-line railway. This is caused by other operating conditions of rail track and switches. In underground railway used special project switches, also there is difference at the construction of rolling-stock chassis, slab track in tunnel, more frequently dynamic load on track. This difference significantly impacts on power dynamics of way’s interaction (switches) with rolling-stock, and accordingly structural will be has other characteristics of abrasive resistance. Researches of abrasive resistance of railway constructions for underground railway operating conditions are almost absent. At the same time are not correctly used this results of researches for main-line railway. That is why, the presented results of wear’s researches main metal details switchʼs point and cross for operating conditions on the Kiev underground main-line railway is actual. Research should make it possible to achieve main regularities of configuring switches’ wear for different switchʼs design patterns and different operating conditions, making it possible to highly predictive of depreciable life, and consequently makes it possible to more effectively allows using of financial and material resources.
