"I saw it come up on my phone, because I get lots of rail-related stuff," Aimee said."I thought 'oh my gosh, that's amazing'."

Aimee travelled the reverse route to get to Aberdeen for the final journey."I am travelling up on the train and down on the train so I'll have seen a lot of the train line," she said.Aimee added that her hope was to "meet some really nice people", have a nice chat, and "generally just enjoy it", while armed with a litre of orange juice.

She explained: "I've got my book, for when it's a bit quieter, hopefully some like-minded souls, talk trains and talk philosophy."I'm very excited about just being there and being part of the whole experience really. It is going to be sad. I'm sure I'll look out for other long train journeys."

Friends Danny, 24, Kieran, 22, and 18-year-old Liam could hardly contain their excitement before heading off.

Danny, from Edinburgh, said: "It's quite a cool journey to do within the rail enthusiast community as it's the longest."Dan's work now forms part of a special exhibition at the National Museum Cardiff, exploring how the valleys were transformed by the explosion of industry and its subsequent decline.

More than 200 pieces of art are on display - including paintings, photography, film and applied art.The exhibition begins pre-industry, when the south Wales valleys were sparsely populated.

During the industrial revolution of 1760-1840, the large scale exploitation of iron and coal began to transform the landscape.As industry boomed, previously rural areas became thriving communities.
