here: M is bending moment, Nm; W is strength moment of rail cross section in respect of flange, [m.sup.3]; [P.sub.i] is vertical dynamic load on rail from rated wheel, N; [[mu].sub.i] and [[eta].sub.i] are coefficients, evaluating influence of contiguous (not rated) axes (bending moment is proportional to the influence line [mu] and load to sleeper; elastic deflection will influence line [eta]); [P.sup.max] is vertical dynamic load on rail from rated wheel, N; k is coefficient of rail and rail flange relative stiffness, calculated according to formula, [m.sup.-1]; f is coefficient, evaluating eccentricity of acting forces; [l.sub.p.m].
