A school girl was listening to music on her headphones when she was killed by a train on a level crossing, police suspect. GP\'s daughter Katie Littlewood, 15, was struck at high speed while using the pedestrian crossing. A pair of headphones were found near her body at Johnson\'s Footpath in Bishop\'s Stortford, Hertfordshire, and British Transport Police said one of their lines of inquiry was that she didn\'t hear the oncoming train because she was using them. Katie\'s mother Ruth White, a family doctor, died from cancer in 2009, aged 49, and the teenager and her sisters Sarah, 17, and Stephanie, 12, moved from Morpeth in Northumberland to live with their uncle and his partner in Bishop\'s Stortford. They moved into a detached four-bedroom house in 2010 that is believed to have been bought with the proceeds of Dr White\'s estate for £625,000 (Dh3.60 million). Katie, who was studying for GCSEs at Hertfordshire and Essex High School, is thought to have been with a friend at the crossing on Saturday. She was hit by the 10.58am London Liverpool Street to Cambridge service. Paramedics pronounced her dead at the scene. London - Gulf news
