Data for: Comparison of Squats and Studs from different traffic environments

3 animations of the 3D models created in VGStudios from CT data volumes derived from scans of in service squat type defects/ studs. 6 videos of scan othroslices showing the defect one slice at a time moving through the rail defect, longitudinally or cross-sectional (marked as x in title). Sample 2 animation is only of branched region of sample 2 defect as large scale scan could not be effectively modelled.3段由VGStudios软件基于对在役压溃型缺陷/螺柱的扫描所得CT（计算机断层扫描）数据体构建的3D模型动画。6段扫描正交切片视频逐切片展示缺陷遍历钢轨缺陷的过程，涵盖纵向与横截面两种视角（标题中标注为x）。样本2的动画仅展示样本2缺陷的分支区域，因大规模扫描无法被有效建模。
