Mumbai, Aug. 19 -- Despite the heavy downpour across the city and the MMR on Monday, local train services remained operational throughout the day, although with some delays in the schedule. Railway tracks between Sion and Kurla on the central line, Matunga and Mahim on the western line, and the tracks along Mankhurd, Govandi, Kurla and Tilak Nagar on the harbour line reported waterlogging due to the heavy and incessant rains. The Dharavi nullah, a 1.8 metre-wide nullah that passes through Sion, Matunga and Dadar, emptying into the Arabian Sea, also runs along the CR and WR tracks. The nullah was clogged, preventing proper drainage of rainwater, leading to overflowing. This resulted in the accumulation of water on the tracks between Matunga and Mahim on the WR lines, and between Kurla and Sion on the CR lines, which is a low-lying area. "Due to the continuous heavy rains, the water accumulated on the rail lines. But the water soon receded, allowing the services to function without hindrances," said a WR official. The WR is equipped with three high-powered pumps of 30 horsepower (HP) each, along with five 50 HP pumps that were installed by the Brihanmumbai Municipal Corporation (BMC), which helped to drain water efficiently. The WR had also employed 110 dewatering pumps, along with the deployment of staff, to keep the drains clear of floating plastic garbage. "The water was slowly draining, which was an issue but the trains continued to operate through the day with a delay of 15-30 minutes," said a CR official. While there were five trains cancelled on the WR lines....
