When checking for track defects near joints, the focus is primarily on which components?

The focus when checking for track defects near joints is primarily on joints and fasteners. This is because joints are the locations where two lengths of rail meet, and they require particular attention to ensure they are properly aligned and secured. Fasteners keep the rail in place, and any defect, wear, or malfunction can lead to misalignment or instability, resulting in potential safety hazards. Inspecting these components ensures that the track functions correctly and can safely support train operations. Proper maintenance around these critical areas is essential in preventing accidents caused by track failures.
