Coaches of last trains leaving CST are being smeared with excreta; a man who boarded one such coach slipped and fell off the train.What used to be a problem in faraway rail yards in Karjat and Kasara - sickos smearing poop inside train compartments – has now reached the Chhatrapati Shivaji Terminus.For some days now, the first two coaches of the last two night trains leaving CST have been covered in excreta, with the miscreants not sparing even the grab-poles of the coaches. Authorities suspect the miscreants are smearing the excrement somewhere between CST and Byculla.Last August, Mirror had reported about how Central Railway trains were being delayed by 15 to 30 minutes as someone was smearing excreta in the ladies’ compartments of trains leaving from Karjat. Authorities had then claimed to have caught a homeless man behind the sick act, but the problem resurfaced in Jan.Last week, the problem took a dangerous turn when a passenger who was boarding a train as it was just pulling out of Sandhurst Road station fell off as he instinctively let go of the dirty handle.Bhandup resident Akhlaque Ahmed, 45, who works as a receptionist at a Colaba hotel, survived with minor injuries, but late night commuters are a worried lot and want officials to nab the psychos immediately.“I took the harbour line till Sandhurst Road in order to catch the 11.58 central line train,” said Ahmed. “It was just about to leave and I got into a coach. It was covered with excreta - not just the handle-bars inside, but also the main pole, seats and luggage racks. I instinctively tried to get off, but by then the train had gathered speed and I slipped. My upper body was inside the coach and my legs were dangling out. I couldn’t walk for three days due to the bruises.”Another regular commuter, Shyam Hande, said it has become a regular issue, adding that he has started dreading the arrival of the train.“We complained to the government railway police at Byculla, but they say they can’t stop the train as it would affect the schedule,” said Hande. “People like me who work till late have no other option apart from the last train. The train is clean when it leaves CST, but someone soils it between CST and Byculla station.”Alok Bohra, CR senior divisional security commissioner of the RPF said he will look into the commuters’ woes. Central Railway’s chief public relations officer Atul Rane said: “We shall put these trains under watch by deploying our men and get to the root of the problem.”
