How To Maintain Tracks in Rainy Season

Check the drainage system and track geometry monitoring

Ensure that the drainage system (including ditches, culverts and gutters) along the track is free of debris and functioning properly. Proper drainage is essential to prevent standing water and minimize the risk of flooding and erosion; regular track geometry monitoring is implemented to detect any deviations from the intended route and contour due to the effects of heavy rain, soil erosion or subsidence. Use track inspection vehicles equipped with laser or GPS technology to detect track defects early.

Vegetation management and ballast maintenance

Prune vegetation along the track to prevent overgrowth, which can impede drainage and increase the risk of debris accumulation on the track. Regular vegetation management helps maintain clear sightlines for track inspections and ensures proper airflow to aid track drying; regular inspection and maintenance of ballast ensures proper drainage and stability. The ballast is cleared of debris and mud and replenished as needed to maintain the desired track geometry and support for the rails.

Tie Inspection and Replacement and Track Bed Stability

Inspect wooden ties for signs of rot, rot, or damage caused by long-term exposure to moisture. Promptly replace damaged sleepers to maintain track stability and prevent track buckling or derailment; address any soft spots or areas where excessive moisture penetration may cause the track bed to become unstable. Use techniques such as tamping, undercutting, or installing geotextiles to stabilize the track bed and improve drainage.
