From the song written by George Jackson and Johnny Henderson, released in 1980 by Otis Clay and a top-chart single for Yazz and the Plastic Population.
These are the railway tracks of the Snowdonia Mountain Railway as seen from the cabin. The trip to the top takes an hour and uses the old trains (steam or diesel) which gives you time to admire the surrounding beauty as you go up and up to the top of Mount Snowdon. It takes another hour to go down. The train is slow both going uphill and vice-versa.
What I found a bit queer is that the engine is at the back and rather than pulls the only passenger-cabin it has, it pushes it forward. Don’t know the reason why but gives passengers a better view of the surroundings.
