Abstract The utility model relates to the technical field of urban rail transit, in particular to a flexible bendable switch rail structure. A front section of the flexible bendable switch rail structure is a dwarf type special section steel rail, a rear section of the flexible bendable switch rail structure is a common steel rail, and the front section is connected with the rear section. Through the flexible bendable switch rail structure, the dwarf type special section steel rail is connected with the common steel rail; since the bending rigidity of the common steel rail is lower than that of the dwarf type special section steel rail, the flexible bendable switch rail structure has the advantages of being convenient to install, safe and reliable, can effectively reduce pulling force, closely attachment counter-force and elastic force in the operating process, and reduce insufficient displacement, thereby ensuring the normal track gauge in front of the heel of a switch rail and reducing the oil coating quantity of a
