Abstract：Research purposes: The discussion and exploration are made on the catenary suspension way for low headroom tunnel in integrated ballastless track experimental section of Suining-Chongqing Railway and the reliable and feasible program is presented for the catenary suspension way for such low headroom tunnel.
Research conclusions: The key points of suspension in low headroom tunnel are how to use the low headroom and satisfy all technical standards along with consideration of the saving materials and construction cost. There are different resolutions to the different headroom tunnels, it depends on the site conditions to adopt the resolution.
