A safety system was “blocked” during a fatal train crash in Powys, an initial investigation has found.
The Rail Accident Investigation Branch (RAIB) has published its initial findings into last month’s collision, in which one person died.
David Tudor Evans, 66, was described as a “lovely guy, full of life and enjoyment”.
A further 15 people were taken to hospital for treatment after the crash near Talerddig, police said.
The collision – at around 7.26pm on 21 October – involved the 6.31pm Transport for Wales service from Shrewsbury to Aberystwyth and the 7.09pm Transport for Wales service from Machynlleth to Shrewsbury.
The RAIB said the units were fitted with wheel slide protection systems – described as being similar to anti-lock braking systems in cars – and an automatic sanding system.
Sand is discharged automatically via hoses when a wheel slide is detected during braking – creating more friction at the wheel-rail interface.

The on-train data recorder shows the wheel slide started during braking and was also present after the driver made an emergency brake demand.
An inspection of the sanding system fitted to Aberystwyth-bound train 1J25 showed the leading vehicle’s sanding hoses were blocked.

The RAIB says they were apparently unable to discharge sand.
The ongoing investigation is also looking at the speed at which the trains were travelling when they collided.

Initial enquiries suggest the westbound train was travelling at a speed of between 15mph and 24mph, while the eastbound train was travelling at a speed of 6mph.
The RAIB says its investigation will look at the sequence of events which led to the crash.
As part of the probe, the agency will look at factors including the actions of those involved, the level of wheel-rail adhesion, and the behaviour of both trains during and after the crash.
In a joint statement, Transport for Wales and Network Rail said they have “fully cooperated” with the British Transport Police, the Office of Rail and Road and the Rail Accident Investigation Branch.
“As investigations are currently still ongoing, we’ll continue to work together with investigators to understand what happened and await the full conclusion and recommendations of the investigation,” a spokesperson said.
The spokesperson said safety was the “main priority” for both companies and they had “carried out enhanced checks to the trains and the railway line”.
“At this early stage of the investigation, it’s fundamental that we await the findings of the full report and show sensitivity towards our customers, colleagues, the local community and the families of those affected by the incident,” they added.
A two-phase statutory public inquiry into the Southport murders has been formally launched.
Home Secretary Yvette Cooper said the first phase would look at the circumstances around Axel Rudakubana’s attack on a Taylor Swift-themed dance class last summer.
It will focus on issues around policing, the criminal justice system and the multiple agencies involved with the attacker who killed three girls – seven-year-old Elsie Stancombe, six-year-old Bebe King and Alice da Silva Aguiar, nine.
It follows the revelation Rudakubana had been referred to the government’s Prevent scheme on three occasions, with the cases being closed each time.
This breaking news story is being updated and more details will be published shortly.
A police officer who was driving a van that followed two teenagers shortly before they died in an e-bike crash will not be prosecuted.
The deaths of Harvey Evans, 15, and Kyrees Sullivan, 16, sparked riots in the Ely area of Cardiff in May 2023.
The officer was facing a dangerous driving allegation but prosecutors decided there was not enough evidence for a realistic prospect of conviction.
A Crown Prosecution Service (CPS) statement said: “We fully understand that this will be disappointing news for the families of both boys and will offer a meeting with them to explain our reasoning further.”
Rumours on social media that the teenagers were being pursued by police were initially denied.
South Wales Police said none of its vehicles were in Snowden Road at the time of the crash.
But police watchdog the Independent Office for Police Conduct (IOPC) later confirmed it was investigating after video appeared to show them being followed by a van – without blue lights or a siren – minutes before the incident.

Other footage, however, showed the van turn off and it wasn’t following the boys at the time of the collision.
A key factor under consideration was whether there was any point at which the actions of the officers in the van “constituted a pursuit”.

Detective Chief Inspector Alex Gammampila, who is leading the investigation, called it “an awful incident in which a teenager has lost his life”.
“The thoughts of everyone in the Met remain with Keiron’s family and loved ones as they begin to come to terms with their tragic loss,” the officer added.
The suspects are due to appear at Highbury Corner Youth Court on Monday.
