The arcing tree, the curved tracks and the misty/foggy weather make for good image. Of course the photographer had to pull it all together in the frame. Well done!
At the risk of alliteration, this is a marvellous misty mood. I love the way that you've picked a spot where the tree forms a curving canopy over the line, and the exposure is just perfect to have the mist graduating out the further you go back. I don't normally say when I vote for an image, I just do it but I'll say so here because it really is an excellent example of the photographic art. (And a remarkably good effort for a little Powershot.) Of course, I'm hoping that you were standing far enough from the line not to get squished when the train finally turned up...
