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 north-west England. The initial conclusion of the accident investigation is that the derailment was caused by a faulty set of points (number 2B), controlled from Lambrigg ground frame. The scheduled inspection on 18 February did not take place, and enquiries are continuing to establish why the faults were undetected.^[1]

[edit] Incident

Train 1S83, the 17:15 Virgin West Coast Pendolino West Coast Main Line service from London Euston to Glasgow Central, a limited stop Pendolino Primo train, was derailed by a defective set of points.^[2] The train was reported to have been travelling at up to 95 mph (150 km/h) when it was derailed.^[1] The train, consisting of unit 390 033 "City of Glasgow", which was constructed at Washwood Heath, Birmingham in 2002, had nine carriages and carried 111 passengers and four members of staff.^[3]

Passengers said that the carriages of the train began rocking and swaying very badly before the train crashed. The train was reported as being evacuated at 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 helicopters, three civilian mountain rescue teams plus RAF Leeming Mountain Rescue Team, and one Merseyside Police helicopter. The rescue operation was impeded by rain, darkness, and access problems caused by the narrow country lanes and muddy fields.^[1] Emergency vehicles experienced difficult conditions, needing to be towed by farm vehicles or tractors after becoming bogged down in mud.

Cumbria Ambulance Service initially reported that the train was six carriages long and that the second carriage had slipped down an embankment, with the carriage trapping up to eight people. Later, a BBC News reporter at the scene reported that all but one carriage had been overturned.

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 least affected. 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. Most injuries occurred in the front two carriages. The driver, who had stayed at the controls, was trapped for about an hour while specialist cutting equipment was used to free him from his cab.^[4] 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 after being admitted to hospital. Her funeral took place on 31 March 2007 at Craigton crematorium in Glasgow.^[5]

[edit] Aftermath

A family liaison centre was set up in Glasgow Central Station for worried relatives.

Within three hours of the crash the site had been sealed off with a five-mile cordon. The line was expected to be closed for two weeks, with Virgin Trains saying that the line would not re-open to passenger services until 12 March 2007.^[6] The recovery operation was slowed by problems in getting heavy lifting gear to the site which required temporary roads to be constructed.

Sir Richard Branson, Virgin Group chairman, visited the scene of the crash at 11:00 the following morning to comment on the incident. During his news conference at the site he said that he regarded the driver, named as Iain Black from Dumbarton,^[7] as a hero, as he had remained in his seat to ensure the safety of passengers.^[4] Mr Black left hospital in late March and stated that "I've got to be in the cab to help the train and it never crossed my mind to leave."^[7]

Branson also later thanked local residents for their help at the scene of the crash, describing how he "was very impressed to hear how those kind people rallied round, opening their hearts and opening their doors to strangers in distress".^[8] Local farmers assisted the emergency services by transporting equipment using quad bikes and four-wheel drive vehicles. Sergeant Jo Fawcett of the Cumbria Constabulary also offered thanks, saying that "There are so many people who have given up their own time to contribute in some way to dealing with the aftermath of the crash that it would be unfair to name them for fear of missing someone out."^[9]

As a result of the suspicion that faulty points were the cause of the crash, Network Rail checked over 700 sets of similar points across the country as a "precautionary measure"^[6] saying later that "nothing of concern" had been found.^[10]

The operation to remove the train from the site began on the evening of 1 March 2007 with the first carriages moved from the embankment. This allowed passengers' property to be retrieved and gave investigators access to the train interior, which previously had not been possible because it would have been unsafe.^[11] The last of the carriages were removed on 4 March 2007 and the A685 road was reopened.^[12]

Trains began running on the line again on 12 March subject to a speed restriction of 50 mph (80 km/h) at the crash site. The first train was the 05:10 Manchester to Glasgow.^[13]

[edit] Cause

Lambrigg ground frame, 660 yards (600 m) south-west of the crash site, controls two crossovers, each one comprising two sets of points allowing trains to cross from one running line to the other in emergencies or during track maintenance work. These points are used only occasionally, operated locally after a release is obtained from Carlisle power signal box. They are normally locked in the main line "running" position. Early statements by Chief Superintendent Martyn Ripley of British Transport Police suggested that investigations would focus on these points.

Investigations were launched by the Rail Accident Investigation Branch and Her Majesty's Railway Inspectorate.^[4] RMT rail union leader Bob Crow said on BBC News that a points failure was responsible for the incident. Experts compared the cause to that of the Potters Bar rail crash in 2002.^[6]

On 26 February, an interim report published by the Rail Accident Investigation Branch outlined the current progress of the investigation.^[3] The report contained a single conclusion, that the immediate cause of the accident was the condition of the stretcher bar arrangement at points 2B at Lambrigg crossover, which resulted in the loss of gauge separation of the point switch blades. The stretcher bars (components that hold the moving blades of the points the correct distance apart) had been found to be disconnected or missing. Of the three bars, one was not in position, another had nuts and bolts missing, and two were fractured. The points in question were facing the direction of travel of the train.

Following the RAIB report, Network Rail released a statement in which its Chief Executive, John Armitt, described how the organisation was "devastated to conclude that the condition of the set of points at Grayrigg caused this terrible accident". He apologised "to all the people affected by the failure of the infrastructure".^[14]

The RAIB report noted that the Network Rail New Measurement Train ran over the site on 21 February. This train uses lasers and other instruments to make measurements of the track geometry and other features such as overhead line height and stagger, and the track gauge, twist and cant. It is not used to inspect points, but it does make a video record of the track which can be reviewed later. The RAIB is currently in the process of reviewing these records.

Commenting on the possibility that the train's video might have been used to detect the points damage and thereby prevent the accident, a Network Rail spokesperson said: "The [inspection] train runs at speeds of up to 125 mph, or 95 mph on this stretch. There would be no point somebody watching it at that speed as they wouldn't be able to pick up any faults. It has to be run in super-slow motion to spot faults. The train runs for up to 18 hours a day, seven days a week. It would probably take someone most of the month to watch one day's worth of data. It's not what it's there for. It's a backwards reference tool."

Network Rail has admitted it failed to carry out a scheduled visual track inspection in the area on the Sunday before the crash.

Bob Crow of the RMT union said: "This is shutting the stable door after the horse has well and truly bolted. We argued this train should not replace visual inspections. Inspectors who walk the track are the eyes and ears of the railway. They don't just check the safety of the track, they look at the area surrounding it, check for signs of potential trouble such as gaps in the fence where vandals could get in." Labour Party Member of Parliament John McDonnell added: "The fact that Network Rail apparently had footage of a missing stretcher bar days before the fatal crash is very worrying."^[15]

As part of the investigation by the British Transport Police, a 46-year-old Network Rail employee from Preston was arrested on 11 July 2007 and released on bail.^[16] Two other Network Rail employees, both from Preston, were arrested in November 2007 and also later released on bail.^[17] All three were due to answer bail in March 2008 but this was extended until the end of June pending further inquires.^[18]

[edit] The accident site

The area near the accident, south of Tebay in Cumbria, is near the scene of a fatal rail accident on 15 February 2004, when four rail workers were killed by a runaway track maintenance trailer.^[19] There was also a collision accident there on 18 May 1947.^[20]

[edit] Subsequent service disruption

Immediately after the accident, all services were suspended and the First ScotRail Sleeper train, the Caledonian Sleeper, was curtailed and passengers transferred to overnight coaches.^[21]

The line closure that followed the initial service suspension saw most Virgin services terminate at Preston or Lancaster from the south, with buses to Carlisle and all stations along the route. There were also several non-stop trains from Preston to London Euston. Local services all terminated short but many were able to make their journeys as their destinations were off branches. The Caledonian Sleeper was diverted via the East Coast Main Line.

[edit] City of Glasgow

The Grayrigg derailment was not the first British Railway accident to feature a train or locomotive named "City of Glasgow" on the West Coast Mainline. In the Harrow and Wealdstone railway accident on 8 October 1952, the locomotive of the sleeper train from Perth to London Euston, whose crew was responsible for the incident, was Class 8P No. 46242 City of Glasgow.
