The black box has been recovered from the wreckage of the Bedford train crash that killed the driver and injured 100 others. Rail investigators removed it from the Luton Airport Express yesterday and placed an evidence sticker on the side. The data recorder will help investigators piece together what happened before the service ploughed into the back end of a stationary passenger train at 5.15pm on Friday near Bedford.The collision killed a train driver instantly and left nine people in a critical condition in hospital. Of the 100 victims, 11 people were very seriously injured, a further 32 were seriously hurt, and 57 others suffered minor injuries, the East of England Ambulance Service (EEAS) said.Network Rail today described the crash as a 'tragic, isolated incident' and announced that rail services will be disrupted until June 28 while a 'complex recovery operation' begins to remove the damaged trains and carriages.King Charles joined senior politicians in offering their condolences following Britain's worst train disaster in 20 years. The monarch said he was 'greatly saddened' and his 'thoughts and sympathies' were with the family of the deceased and those affected. Specialist crane equipment has also arrived this morning at the crash site, just south of the Elstow interchange between the A421 and the A6, which will be used to lift the two trains off the tracks.The Rail Accident Investigation Branch (RAIB) said on Saturday that its inspectors continued to gather evidence at the scene.'RAIB will conduct a full, independent safety investigation into this tragic accident,' the agency said in a post on X.'We will provide a further update in the coming days once we know more.' Rail investigators have removed the black box from the wreckage of the Bedford train crash that killed the driver and injured 100 others New photos taken today show the crash site in what is Britain's worst train disaster in 20 yearsThe closure of the line between Bedford and London St Pancras means there will be no Greater Thameslink Railway services north of Luton and no East Midlands services south of Bedford.Ellie Burrows, Network Rail Eastern regional managing director, said: 'Colleagues from across the rail industry are working together at pace to remove the trains and carriages from the railway, and complete the repairs to the tracks.'This is a complex and challenging task, and our teams will be working tirelessly to reopen the railway so we can resume services between Bedford and London.'While investigations are still at an early stage, current indications are that this was a tragic, isolated incident.'We are focused on the safe reopening of the railway and getting services running as quickly as possible.'As part of recovery work, the overhead wires which provide power to electric trains will be removed and a temporary access road will be built for a crane to get close to the railway line.Two 110-tonne Kirow cranes on the track will then lift the trains and carriages from the line, then a road crane will move them on to a trailer to be taken away by road, before engineers inspect the railway.This work is expected to take days, during which time no EMR services will run between Bedford and London St Pancras.Trains that usually start and terminate at London St Pancras will start and terminate at Bedford instead, and there will be a reduced service on some other lines.From Monday, north of London St Pancras towards Bedford, Thameslink will run a limited service as far as Luton only.Speaking at a press conference near the scene on Saturday, British Transport Police Chief Constable Lucy D'Orsi said: 'There will be a lot of questions as to what exactly happened on (Friday) night.'I would like to reassure everyone that specialist investigators from British Transport Police are working with colleagues at the Rail Accident Investigation Branch to gather the facts and determine what has happened.'They are extremely experienced and I would ask that we all refrain from speculation.'The front of the 4.40pm departure from Corby to London St Pancras was crushed when it crashed into the rear of the 3.50pm departure from Nottingham, to the same destination.The Corby train also had damage to the rear of the carriages which had been shunted into the ones in front.Mobile phone footage showed blood-covered victims on carriage floors and others staggering around a nearby field.One survivor likened the crash impact to 'a bomb explosion' and said most people in his carriage were 'bleeding profusely' or couldn't stand.Passenger Pete Knapp described people 'crying, screaming' and said some seemed to have major injuries.Dr Knapp said: 'There was a moment of being flung into the chair in front, and then I saw smoke.'People were crying, screaming, people were so scared and confused.'The 40-year-old said he saw people with 'life-threatening, major injuries, minor injuries' as well as 'people with bandages, people who couldn't see straight', while others like him were still able to walk.Brett Byatt, another passenger on board, told the BBC he was among three or four people in his carriage who were not injured, adding: 'Everyone else had either a serious wound that was bleeding profusely, or a situation where they couldn't stand, or couldn't move their neck, or I saw a woman's snapped leg.'Mr Byatt, a teacher, who lives in Bedford, said he was feeling 'angry' the morning after the collision.'I don't know at whom, who specifically, but it's more about we've got one of the oldest railway networks and signal failures happen a lot, and now I'm just wondering… why wasn't that signalled to my train and why did that train driver lose his life over this?' he said.Buckingham Palace said the King was 'greatly saddened' by the crash and that his 'thoughts and sympathies are with the family of the deceased and with all those injured or affected by such a tragic incident', while Prime Minister Sir Keir Starmer said in a post on X that he had spoken with the chief executive of EEAS.'I expressed my gratitude to the air ambulance crews, the emergency services who responded under extremely difficult circumstances, as well as the NHS staff taking care of the injured,' Sir Keir said.Rail expert Tony Miles, from Modern Railways magazine, said the crash was puzzling 'because if the track is occupied, it shouldn't be possible to clear the signals'.Mr Miles said that while a driver could theoretically decide to cross a red signal if they wanted to, 'they would normally only do that because they had been given permission by a signal box because there was a fault'.He added: 'Obviously it's a rear-end collision, they were going in the same direction, so the rear one was going faster than the one it caught up with for some reason.'So the question must be how that train has got into contact with the train that it was following.
