Resumen
The basic stages of introduction on railways of cross ties from ferroconcrete are resulted. The data on rates of laying and extent of a railway on the ferroconcrete basis on Russian and Byelorussian railways are resulted. It is shown, that the width of a rail track at different levels from a surface of the head of a rail considerably differs because of canting. The experimental researches confirming the conclusion are executed that existing practice of measurement of width of a rail track promotes its actual narrowing. The way of fastening of clip of an intermediate compound in stationary conditions and on the worked way is considered, allowing to prevent above permitted standard narrowing of a rail track.
