Looks good. I have just one comment. In your picture of the long train, you’ll notice that the background of the picture is in focus, but the foreground is blurry. As you compose your picture, aim your camera about 1/3 of the way from the bottom of the viewfinder/screen. If you have a tripod, that’s even better. Set your camera to it’s highest F-stop. This will give you the greatest depth of field.
ok it goes from upper to lower the lower level i use to park extra rolling stock (700+) and engines the helix is20"from top to bottom 54" for center of track and 3 1/2" for each level
