The Grayrigg derailment was a fatal railway accident that occurred at approximately 20:15 GMT on 23 February 2007, just to the south of Grayrigg, Cumbria, in the North West England region of the United Kingdom. The initial conclusion of the accident investigation is that the derailment was caused by a faulty set of points (number 2B) on the Down Main running line, controlled from Lambrigg ground frame. The scheduled inspection on 18 February 2007 had not taken place and the faults had gone undetected. The points which caused the derailment, and points 2A on the opposite line, were removed from the track following the derailment and the line is now welded continuously for including the line over the Docker viaduct. The derailment also brought down the overhead line equipment which had to be replaced. Modern double-line catenary from a single stand was used for this, which reduces the risk of carriages bending if a derailment occurs, for example becoming wedged between the overhead line stanchions as seen in the Southall crash. Although the accident killed far fewer people than some other accidents on the West Coast Main Line, it had a major negative impact on Network Rail's safety record. == Incident == The 17:30 Virgin West Coast ''Pendolino'' West Coast Main Line InterCity service from London Euston to Glasgow Central derailed at 20:15 by a faulty set of points almost immediately after crossing the Docker Viaduct (the rear half of the train would still have been crossing the bridge whilst the front derailed at the points). The train was reported to have been travelling at , when it was derailed. The train, consisting of unit 390 033 ''City of Glasgow'', which was constructed at Washwood Heath, Birmingham, in 2002, had nine carriages and carried 105 passengers and four staff members.〔(【引用サイトリンク】title=RAIB interim report into a derailment at Grayrigg, Cumbria 23 February 2007 ) Note: passenger numbers subsequently revised from 111 to 105 in final report.〕 Passengers said that the carriages of the train began rocking and swaying violently before the train left the rails and careered down an embankment, with the first carriages jack-knifing and most of the train coming to rest in a field. The train was reported as being evacuated around midnight. Emergency crews scanned the train with thermal imagery equipment to make sure there was no one still inside. Up to 500 rescuers attended the scene, along with at least 12 ambulances, at least five fire engines, three Royal Air Force Sea King search and rescue helicopters, the International Rescue Corps, three civilian mountain rescue teams plus RAF Leeming Mountain Rescue Team, and one Merseyside Police helicopter. The rescue operation was hindered by rain, darkness, and access problems caused by the narrow country lanes and muddy fields.〔 Emergency vehicles experienced difficult conditions, needing to be towed by farm vehicles or tractors after becoming bogged down in mud. The train's derailment caused severe damage to the Overhead Line Equipment and tripped the entire circuit between Brock (near Preston) and Tebay resulting in a number of other electric-powered services coming to a halt and all signalling equipment immediately turning to danger (red) in accordance with the system's fail safe design. Live BBC television coverage at 08:15 the following morning showed that although the whole train had been derailed, the rear carriages were standing nearly vertically on the sleepers and ballast. Standard class, the front five carriages, were the worst affected, and the rear four first class carriages were in better condition. The leading carriage, a driving motor coach, had headed down the embankment, and turned end-for-end as it fell. It was lying on its side at the foot of the embankment. The second carriage had jack-knifed against the first, breaking the coupling, and so had not followed it down the bank. This second carriage came to rest some distance further along the track, at a steep angle with one end in the air. The middle part of the train toppled sideways down the embankment. All the carriages remained structurally intact, with damage mainly confined to the crumple zones at their ends. None of the windows broke, and lighting remained in all the carriages. Most injuries occurred in the front two carriages. The driver, who had stayed at the controls (but had little option to move once the accident had started and had no prior indication of derailment), was trapped for about an hour while specialist cutting equipment was used to free him from his cab.〔 The other three members of the crew were in the rear first class section of the train. Survivors were initially received at Grayrigg Primary School, which had been opened as a Survivor Reception Centre. Hospitals in the area, including some over the Scottish border in Dumfries and Galloway, were put on standby, but not all received patients. According to BBC News, five passengers were admitted to Royal Preston Hospital in a critical condition. Police later released a statement revealing that one passenger, 84-year-old Margaret Masson from Glasgow, had died in hospital. Her funeral took place on 31 March 2007 at Craigton crematorium in Glasgow.〔(【引用サイトリンク】title=Rail Victim's Funeral )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Grayrigg derailment」の詳細全文を読む スポンサード リンク
