Crash investigators are focusing on a set of points as they try to establish what caused a high-speed rail derailment in Cumbria. An 84-year-old woman, Margaret Masson, was killed and 11 people, including her daughter and son-in-law, were seriously injured after a Virgin Pendolino train left the track. British Transport Police said it was a miracle there weren't more deaths. The train left London's Euston station at 5.15pm on the 23rd February 207. It was headed for Glasgow. At 8.16pm, travelling at 95 miles an hour, the train crashed at Grayrigg, near Kendal in Cumbria.
