i see in pictures the tracks are angle a little bit. How do the do this? Do they shim the track and if they do were and how do they do it.
This is called superelevation. One way is to put layers of masking tape under the outer ends of the ties, you could also glue thing strips of plastic, etc. Remember that you need to transition from flat track raising it gradually. Since this doesn’t add to operational quality for our models, you only want enough thickness for effect, 4 to 6 scale inches should be enough.
