Station guard Dilwyn Davies, aged 60, of Ddol Road, Dunvant, was killed while working at Gwili Heritage Railway in Bronwydd.

An inquest heard how, on July 19, 2006, Mr Davies was involved in the coupling of two shunting coaches at the tourist railway when the accident occurred.

Graham Powell was driving the locomotive at the time of accident. He gave evidence at the inquest.

"I had agreed with my colleague Barry Frobel that we should add another carriage to the engine because it was going to be a busy day," he said.

"He had agreed to be my shunter, which meant he would guide the two carriages together.

"I believe I saw Barry give me the 'buffer up' signal to move towards the carriages. I thought Barry would do the linking up.

"I didn't expect Mr Davies to take part. There was no prior arrangement for him to do so.

"I heard Barry shout 'stop stop stop'. Somebody also shouted 'Dil's in there - he's trapped.'

"I tried to move away but couldn't because the carriages had locked together.

"I had to get out of the train and run to help Barry pull a chain to release the carriages.

"I know now that by the time I moved off again it was too late."

Coroner John Owen said: "Mr Davies's death was the unintended consequence of an intended action. He suffered crushing to the abdomen and chest after he was trapped between two carriages of a steam locomotive."

A jury of nine agreed on a verdict of accidental death caused by multiple injuries as a result of a railway accident.
