Mumbai, Nov. 10 -- Diwali firecrackers also disrupted suburban train operations, delaying trains by 20-30 minutes on Western Railway on Monday morning. Firecrackers bursting sparked a fire along railway tracks between Nallasopara and Virar late Sunday night, damaging signalling equipment and disrupting train operations on the Virar-Churchgate rail corridor. The fire was reported at 11:20 pm after unidentified people allegedly burst crackers along the rail lines. "We found burnt firecrackers at the site. The dry grass burst into flames; the fire was extinguished by 11:50 pm," said a WR official. Railway staff rushed to the spot and extinguished the fire in 30 minutes, but signalling cables close to the tracks were already damaged by then. On Monday evening, the WR authorities said the fire incident between Virar and Nallasopara damaged 20 signalling cables. This affected seven signals in the section on both Up and Down lines. The damage disrupted train operations, delaying 14 suburban services on Sunday night. The impact was greater on Monday, with 35 services cancelled and 150 trains delayed. "Restoration work is underway, and railway staff have laid additional cables to repair the damaged signalling network. Complete restoration is expected by the night of November 9-10," said a WR official. The fire affected signalling equipment, which resulted in the failure of multiple track circuits and forced WR to operate trains under restricted conditions, running 20-30 minutes behind schedule between Virar and Churchgate. The impact also affected long-distance services....
