Indirect method of determining pollution concentrations of train track surface runoff

Summary

The classification (categorization) of the train track and railway station ballast section pollution density has been developed and approbated. Each category of train track pollution density is specified and the criteria of the space interval attribution to a pollution density category are presented. The pollution concentration of train track surface runoff as a function of the ballast section pollution density is determined.
