Alan Pegler was four when he was taken by his parents to the British Empire Exhibition of 1924.

"I was lifted into its cab," he said in an interview with the Railway Magazine.
"I remember being impressed at how clean it was, compared with the grimier engines we saw at home, and how marvellous its apple-green paint was.
"I was spellbound and couldn't stop thinking about it all the way home."
