A 5-year-old girl became separated from her mother when getting on a Red Line train, with the child hysterical on the train and the mother left on the platform. The train operator stopped the train while still at the station but refused to reopen the doors, according to a rider on the train.

“The operator should have opened the door,” said Jessica Stallings, 27. “You shouldn’t leave a 5-year-old with strangers. It was lucky, there were a lot of concerned passengers.”
