Analysis and specifications of filtration of surface runoff from railway track ballast section

Summary

Rail transport facilities are fixed structures that produce continuous impact on the environment. The main facilities – pollution sources among rail transport facilities are railway stations. In most cases polluted runoff from railway station tracks generated mainly as a result of atmospheric precipitations leaks through the surface relief, infiltrates into the subsurface, penetrates deeply and drains with underground water into the nearest water bodies. The processes of surface runoff filtration through multilayer porous media that are taking place in the ballast section of the railway track have been analyzed and specified. Possible hypotheses of liquid behavior and properties in multilayer porous media, in particular of the liquid on the surface of ballast section of the railway track accumulated as a result of atmospheric precipitations; steady and unsteady liquid seepage into the railway ballast depth; dissipation of oil product spills on railway tracks are presented.

Surface runoff pollution of water bodies

Summary

The results of studying the water of the Kondurcha River in the Samara Area and surface runoff from one of the railway stations are presented. The comparative analysis of the results of studying water samples from the water body in the monitoring section is given. The prediction of water quality changes in the water body for the next several years in relation to the following pollutants: BODfull, suspended solids, oil products and total iron is presen­ted. The trend of the growing negative impact of polluted surface runoff from the surroundings of railway objects on water sources persists owing to the growth of cargo tonnage; the concentrations of pollutants in the water bodies are increasing.

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.
