As most of you probably know, the Loch Ness trains used to be timed to simultaneously pass through the interlocking loops. I had an idea to recreate this discontinued event by taking two images of a train in each loop and then using Photoshop to place the position of one train onto the empty loop in the alternate image. I took the pictures on the same day as when I photographed the extended queue, but wasn't able to finish the editing until this morning. This is result after PS editing, as taken from the Rhinefeld side of the bridge (pictures are large):
