Abstract: Due to the rare precedents of modern tram underground stations in China, there are no special norms and standards to follow. The design of modern tram underground station applying the relevant regulations of urban rail transit will inevitably increase the scale of station civil construction, the mechanical and electrical equipment system, therefore is neither reasonable nor economical. Based on the tram underground station design on the Line 1 extension in Suzhou High-tech Zone, the station setting principle, architectural design scheme, the major and difficult design issues are discussed. According to the characteristics of modern tram system, and under the premise of ensuring the safety of operation and the functions, corresponding suggestions are proposed, such as the setting of level crossing channels, introducing the natural light and simplifying station functions, reducing the station size and increasing its permeability, in order to reduce the station safety hazards.
