'Loving' Margaret Masson died in hospital after the crash

Margaret Masson, 84, from Glasgow, was travelling with her daughter and son-in-law and died in hospital, four hours after Friday night's derailment.

In a statement, her four grandchildren said they would miss their "nan" - known as Peggy - tremendously.

The family also praised the emergency services and Virgin Trains.

Their parents, Margaret and Richard Langley, are in a serious but stable condition in the Royal Preston Hospital.

In a joint statement, the Langley children, Moe, Carol, Margaret and Jimmy paid tribute to their grandmother.

"The whole family is completely devastated about the loss of our nan, Peggy," they said.

"This grief has been harder to deal with due to our parents being involved in the accident, too. Thankfully, both seem to be recovering well.

"Our nan was a generous, loving lady who we will all miss tremendously.

"Our parents are aware of our nan's passing and both are understandably upset."

They added: "We cannot thank all the staff at the Royal Preston Hospital enough for the wonderful care and attention they have given both to us and especially our parents."

'Wonderful' person

Mrs Masson, from the Cardonald area, had been visiting the Langleys in Southport, Merseyside.

She was on her way back home when the train crashed.

Train driver Iain Black has been hailed a hero

Her neighbour Laurence McGeady said news of her death was an incredible shock.

"It is something we're trying to come to terms with, our hearts go out to the family," he told BBC Scotland.

"She was a wonderful human being, full of life, very intelligent, always up for a laugh, always laughing, incredibly active and fit.

"She couldn't do enough for you, she was just fantastic."

A close fried of Iain Black, 46, the train driver, has said he was "very brave".

Mr Black, who suffered a broken collar bone and a broken bone in his neck, is said to be in a serious but stable condition.

His hairdresser Carol Paul said: "It is totally amazing what Iain has done, I'm not surprised he sat at the wheel and didn't try to save himself.

"He'll be devastated by the woman dying."

Survivor Graeme Stewart, a Glaswegian IT consultant who works in London, is recovering in hospital after being thrown from his seat when the train left the tracks.

He said: "It eventually stopped and there must have been a few seconds of silence and people started groaning.
