Randomized trial demonstrates effective rail defect segmentation in railway systems, indicating significant practical potential.

The aim is to develop an accurate segmentation method for identifying rail surface defects, enhancing railway safety.
Integrated deformable convolution with a spectral–deformable transformer for segmentation.
Utilized a multi-scale strip-aware deformable convolution and a feature-gated fusion module in the model design.
Collected rail surface defect images for training and constructed a defect segmentation dataset.
Achieved 74.89% mean Intersection over Union (mIoU) and 85.38% F1 score on the test dataset.
Demonstrated robust segmentation capabilities for slender rail defects under complex conditions.
