The removal effect of citric acid on black leaf layer on rail surface caused by fallen leaves

In the mountainous areas in Japan, wheels frequently slip or slide in autumn due to the black leaf layer on the rail head caused by fallen leaves. In this study, the effect of citric acid on the facilitating the removal of black leaf layer is investigated in laboratory and field tests. It is found that supplying a higher concentration of citric acid aqueous solution is more effective in removing the black leaf layer, but the rail head should be washed with water immediately after removal.
