The invention discloses a flexible turnout beam section for a saddle type single track traffic track. The flexible turnout beam section comprises a traveling support and a flexible beam body which deforms in a flexible manner along a horizontal direction. The traveling support comprises a traveling face and a flexible side supporting plate. The structure of the flexible turnout beam section is formed by a flexible turnout beam section which is flexibly deformed forcibly. Flexible deformation driven by external forces occurs when the flexible turnout beam section is jointed with the track which transfers. A guide face and a stable face of the flexible turnout beam section are in smooth transition, fold lines are eliminated, so that a light rail train can pass through. Compared with the conventional turnout beam structure, structure of the flexible turnout beam section for the saddle type single track traffic track is greatly simplified, manufacturing cost is lowered, manufacturing period is shortened, service life is longer, and use and maintenance costs are saved. Traveling comfort and safety of a light rail can be ensured and traveling noise of a vehicle is reduced, so that the flexible turnout beam section for the saddle type single track traffic track has a better environmental performance.
