Questions remain unanswered about the horrific Bedford train crash that left one person dead and 100 injured, as investigators continue to work to establish the cause of the crash.
One train struck the rear of another on the same line shortly after 5pm.

Twenty-eight people remain in hospital, including nine in a critical condition. One person — the driver of one of the trains — sadly died following the crash.
He has since been named as 60-year-old Shaun Burton. His family say they are “devastated” by his loss, as they expressed their sympathies for all those affected by the crash.
Transport Secretary Heidi Alexander has said works are being carried out to understand the circumstances of the crash so that “lessons are learned”.
When asked about the potential cause of the collision, she said: “It is too early to speculate and that’s why it’s so important that the inspectors from the rail accident investigation branch were there very quickly.”
The Standard has put together a list of the questions around the crash that are yet to be answered.
Why did the first train stop?
Investigators are understood to be examining why the first train — the Nottingham to London service — came to a halt on the tracks near Elstow, just minutes after leaving Bedford.
Early reports indicate a possible technical fault, although this has not yet been officially confirmed.
Why did the second train also not stop?
At the same time, investigators are also looking into why the second train was unable to stop after the line became obstructed.
Modern British railways have safety systems in place to prevent incidents of this kind.
As part of the inquiry, officials will examine whether the driver of the second train received the correct information and adequate warning, as well as whether the train’s braking systems operated properly and how effectively the safety mechanisms performed.
Was there a signal failure?
The Rail Accidents Investigations Bureau will also consider whether there was a possible signal failure that caused the crash.
Investigators will probe whether the signals correctly indicated the track ahead was occupied; whether a signalling fault occurred and whether control centres had accurate information about train positions.
Tony Miles, a rail journalist, said on Sky News: “Were the signals showing red and the train went past them?
“Or were the signals showing that the line was clear, and if so, how were they able to know when the train in front was stopped?”
Was there a fault with one of the trains?
One of the trains involved was a relatively new Aurora fleet unit, investigators have confirmed.
Data recorders, often referred to as “black boxes,” will be downloaded and analysed to determine a timeline of events leading up to the collision.
They will focus on braking performance, onboard computer logs, communications systems, and any technical faults in the lead-up to the collision.
Could there have been a human error?
There is currently no evidence to suggest driver error, though investigators will need to rule it out as part of their inquiries.
They will also examine communications between the driver and the signaller, along with whether factors such as fatigue, workload pressures, or inadequate training may have contributed to the incident.
