The Talyllyn railway seemed familiar despite having never been there before. This was partly due the the Talyllyn being a popular prototype to model (for example Quarry Sidings and Rheilffordd Cilcewydd on NGRM Online) and partly due to reading Rev. W. Awdry's books, in particular The Little Old Engine which has an illustration of Dolgoch Viaduct which stuck in my head.
For more information on the Talyllyn take a look at their website or it's article on Wikipedia which is a featured article.
Here's the thumbnails of my photos:
