CAMBRIDGE - A derailed Green Line train in Cambridge has finally been moved, about a day-and-a-half after it derailed. That's the good news for Boston area commuters. The bad news is shuttle buses are still running for now. Seven people were hurt Tuesday evening when the train derailed after leaving Lechmere station around 5 p.m.
