Thanks chaps, especially for the photos!
The turntable will form the front of the layout so I probably will not include them, though I might make them as a background for photos. I have found this perfect angle of the coaler: https://www.flickr.com/photos/irishswissernie/5857145827. In order to create this I will probably a cut in the board, as it is raised, for the line to fit.
