The British Transport Police have apologized to the family of a man who died when two trains collided in Powys.
David Tudor Evans, 66, died after two Transport for Wales trains collided at Talerddig, near Llanbrynmair in Powys at 19:26 on 21 October.
A close friend of the family has now accused the British Transport Police (BTP) - who are investigating the incident - of failing to support the family.
On Thursday the police officially apologized.
Speaking to the PA news agency, a friend of the family said: "The truth is that Rachel Evans - Mr Evans' wife - on the night of the collision was left alone without adequate support."
On 22 October the police issued a statement which said, "the next of kin of the deceased have been informed and his family are being supported by specialist officers".
But a specialist police officer did not visit until Wednesday 23 October.
The friend also said the family disagreed with media reports suggesting a cause of death.
"At the moment, the reports say that the cause of death was not related to the collision and there is no evidence of that," he said.
On Wednesday the inquest into the cause of Tudor Evans' death was opened and it was noted that the cause of death had not yet been recorded.
Superintendent Andrew Morgan of the British Transport Police said: "We would like to apologize for the statement issued in error shortly after the train collision which occurred on Monday 21 October in Llanbrynmair.
"British Transport Police have apologized directly to the family of the deceased for this statement and would like to publicly apologize for any additional suffering caused at this extremely difficult time."
During the inquest on Wednesday afternoon, Ceredigion's assistant coroner, Louisa Corcoran, said that a post-mortem was underway, and therefore that a medical cause of death had not yet been recorded.
Ms Corcoran explained that an inquest date had not been appointed, and that they have not set a date for a pre-inquest hearing either - due to the "complexity" of the investigation.
Four other people were seriously injured during the incident, and a further 11 were treated in hospital.
According to the Rail Accident Investigation Branch, RAIB, initial investigations suggest that the level of grip between the wheels and the track was low, and that the train slipped while trying to come to a stop.
They added that initial investigations also suggest that the accident happened at a speed of 15mph.
