Ivor the Engine?
It should have been, but this train was actually called "The Prince of Wales". It is part of the Vale of Rheidol Railway stock and pulled us all up on an amazing journey through spectacular scenery from Aberystwyth to Devil's Bridge. The journey takes an hour there and an hour back, with time to explore the Devil's Bridge Waterfalls and the Three Bridges at the top.
My daughter has hip problems, so she and I watched from the top bridge as my husband and son-in-law tackled the 200 or so steps to reach The Devil's Cauldron at the bottom (see extras). Rather them than us!
The weather was a bit misty on the way up, but cleared on the way down so the views were wonderful.
