At the end of last summer we went to Hayling Seaside Railway for one of their steam weekends. Emmet was the visiting locomotive. The railway is just over a mile long according to Wikipedia and the scenery isn't that varied, but I've always had a soft spot for railways on beaches, and despite some very heavy rain we had a great afternoon out.
There's more of my photos on Flickr, and a slightly longer post on my blog.
