The construction and circulation of railways, especially urban rail transit, change the travel patterns of residents along the lines and provide convenience for residents in outer suburbs to enter the city center. At the same time, urban rail transit will likely have an impact on the social structure and types of residents in the area. This paper explores the urban gentrification caused by railways in mainland China, covering the old city renovation plan, demolition along the subway line, subway line terminus, and other perspectives. The findings show that with the development of urban rail transit, land prices in the area will increase and communities will become gentrified, which means possible crowding out of low-income citizens. This article intentionally explores the relationship between the subway and gentrification.
