In a significant infrastructure upgrade, the Western Railway has enhanced the drainage capacity along the Mahim–Bandra stretch in Mumbai, addressing a major bottleneck that has plagued local train services for over 30 years. The new 1200 mm pipeline replaces an outdated 300 mm pipe, allowing nearly four times more rainwater to flow through, which is crucial for the 3 million daily commuters who rely on these services. Previously, severe waterlogging during monsoon seasons caused frequent flooding on the tracks, leading to delays and overcrowding at stations. The old drainage system, Culvert No 22, had become nearly non-functional due to debris accumulation and encroachments. The upgrade was completed over a 36-hour period, overcoming significant engineering challenges in a congested area. Railway officials anticipate that this new drainage system will improve the outflow of rainwater, thereby enhancing train operations during peak monsoon conditions.
