Passengers waiting for the AC local at Bandra station were left flummoxed when the train’s doors did not open upon its arrival, on Monday. Some commuters who were on board also faced inconvenience as they were unable to alight at Bandra.“As the doors did not open at Bandra, the passengers had to deboard at Dadar station,” said Rajeev Singhal, a commuter activist.“The AC train reached Bandra station around 2.15 pm on Monday. It stopped, but its doors did not open. It went away, leaving some waiting passengers behind. Our tickets went waste,” said commuter Subhash Shinde, 38.When contacted, Ravinder Bhakar, CPRO, Western Railway, said it happened because of the guard’s mistake. He added that the operating department will take appropriate action against him.
