  • What are the sources of water pollution in the railway industry?
  • Leakages of petroleum products from fuel storage tanks, filling stations, locomotives and transformers are also frequent sources of water pollution. Risks from oil leaks are directly proportional to the share of diesel locomotives in the railway industry.
  • Is water pollution from the railway industry an insignificant issue?
  • This lack of interest does not imply that water pollution from the railway industry is an insignificant issue. As Osborne and Montague (2005) stated, “railway operations, both current and in the past, have the potential to give rise to pollution, as water drains from the railway into water courses”.
  • How to reduce pollution along railway tracks?
  • As mentioned earlier, pollution along railway tracks is mainly accompanied with fine fractions. It means that removing fine particles could reduce high fraction of impurities. Therefore, increasing the frequency of ballast cleaning can reduce the accumulation of contaminants onto track beds. 4.2. Stormwater treatment and harvesting 4.2.1.
  • Which adsorbent material is best for removing pollutants from wastewater?
  • Activated carbon (AC) is considered the most efficient adsorbent material for removing many types of pollutants from wastewater (Azam et al. 2025; Liu et al. 2025). AC is non-toxic and low-cost material with high efficiency because of the porous structure and large surface area (Kamaraj et al. 2025).
