I am planning my first layout (n scale) and was wondering what code of track to use. One person said that using code 55 for a first layout is a bad idea and that I should leave it for when I am more experienced but I like the look of code 55 much more than 80. Is there a major difference between code 55 and 80 derailment wise? Most of my current rolling stock (about 15 cars) have low flange wheels and dont derail on my code 80 test track and I can't see how code 55 will derail them as the flange will still be the same. Any thoughts?
