Justification of classification and terms of replacement defective rails
Keywords: Defects of rails, diagnostics, defektoskopny means, survivability of rails, efficiency, nondestructive control, defect code, outsourcing
On the basis of the analysis of an exit of rails on the Moscow management of infrastructure, theoretical researches on estimates of survivability of rails and features of development of rail flaw relating to defective rails classification the defective rails on a danger class is offered, overall performance the defektoskopnykh of means is estimated and offers on transfer of system of diagnostics of rails on outsourcing are given.

Strained and unstrained roughnesses
Keywords: strained roughness, unstrained roughness, theory of creep, rheological constants.
The difference of notions strained and unstrained roughnesses is described in the article. Emergence of strained roughness is connected with reduction of cross running resistance, which can be explained with the theory of creep, and increase in the longitudinal compressive force.

Modelling of track like a spatial object
Keywords: a plane of line, an involute of line, a slope length, a run.
In this article existing methods of modelling of the railway track on the two-dimensional space are described, these methods’ disadvantages and errors are refered. It was proposed to use the spatial character of the railway track for avoiding errors; the basic provisions of this method are stated.
