- Periodic inspection of railway track structures includes inspecting the condition and components constituting the railway track structure.- Periodic inspection of the railway track structure is carried out at least once a year, from the date of the periodic inspection of the previous inspection period.- Based on the condition review of the railway track structure, if it is necessary to shorten the inspection cycle, a corresponding new inspection cycle must be prescribed and inspections conducted according to that cycle.- In the case of large-scale construction replacing the entire component or installed equipment, the above-mentioned periodic inspection date applied to the post-construction works must be newly defined.- Temporary suspension of inspection in the following cases:
- Due to thunderstorms, natural disasters, accidents, or incidents.- Suspension of inspection to prioritize handling natural disasters, accidents, or incidents at other locations.
