Abstract: ［Objective］ When turnouts are laid on slope, the longitudinal force increase on the track due to the cyclic braking of trains will cause uneven rail creeping phenomena， resulting in a more complex stress and deformation pattern for the turnout, and even affecting its normal service. Therefore, it is necessary to study the characteristics of stress and deformation of large-slope turnout rails under cyclic braking loads. ［Method］ Tests on fastener longitudinal resistance under CLA (cycling loads action) are conducted, and a non-linear finite element model of the No.9 turnout is established to analyze the turnout rail creeping pattern under CLA. ［Result & Conclusion］ The fastener system exhibits resistance degradation under CLA. The maximum creep of the turnout rail occurs after the first train braking. Under CLA, the cumulative increase in rail creeping gradually stabilizes with the increasing number of CLA. The presence of slope will significantly increase rail creeping amount under CLA. The train loading form has minimal influence on turnout rail creeping under cycling braking loads action.
