After last year's heavy water-logging in the Virar-Nallasopara section, the Western Railway and IIT Bombay have conducted a hydrographical survey of the region. This entails strong emphasis on soundings, shorelines, tides, currents, the seabed and submerged obstructions in addition to a planned drone survey and placement of Automatic Rain-Gauge by the Indian Meteorological Department at six stations.

"The 2018 water-logging in Virar-Nallasopara area in 2018 had adversely affected train movement for several hours. In order to ascertain the constraints to free-flow of storm-water in this area, the Western Railway has undertaken dredging and desilting of drains and nullahs running parallel to the railway tracks and connecting to Vasai-Vaitarna creek. Work is nearly 60% complete and the remaining is targeted to be completed by May 30.
