To solve the stability problem of continuous welded rail (short for CWR) on bridge in the small radius curve section, a sleeper connector structure was proposed, which is used to connect sleepers together and strengthen the stability of CWR. A FEM model was established to study the effect of the CWR stability strengthening scheme. This study result shows that the integrity of the track structure and the stability of CWR in the small radius curve section of which the radius is from 250 m to 600 m will be both improved by the strengthening scheme, and the larger the curve radius is, the better the CWR stability improvement will be. In order to guarantee the strength of sleeper connector and connecting bolt, it is suggested that the sleeper connectors at beam gaps should not be connected, and small resistance fasteners should be used in strengthening area.
