Therefore, the work force size, organization of labor must meet the set tasks and conditions. The introduction of a sectional system of track maintenance, new technologies, automated complexes of track machines compels to revise the standards of track maintenance, the better use of production resources. Keywords: railway, track current maintenance, sectional system, organizational structure, number of track servicemen.

The paper presents a mechanical and mathematical model for estimating the wear of rails in the form of a generalized indicator called the wear factor, which includes the total relative sliding caused by turning the truck when entering the curve and rotating the wheel. The wear factor also includes the normal pressure at the point of contact between the wheel flange and rail, the contact area, the friction coefficient, and the coefficient that takes into account the wobble of wheel sets.
