The problem of heavy metal pollution is a hot issue widely at home and abroad, and the heavy metal residues in food is also getting more and more attention. In recent years, with the continuous development of China's economy, railway transportation has also developed into one of the main land transportation modes. The dense railway network communicates with the north and the south, making it convenient for people to travel and transport goods. But while creating convenience, environmental problems brought about by the operation of the railway have gradually attracted people's attention. One of the main environmental problems brought about by railway transportation is the heavy metal pollution of the soil along the railway, and it has great ecological potential risks. This paper discusses the sources of heavy metals in the soil along both sides of the railway in China using the existing literature, summarizes the impacts and potential ecological risks, and provides suggestions for remediation of heavy metal pollution in soil.
