Being new to this outdoor part of model railroading, I am spending a lot of time reading everything I can about it as I plan my railroad. This site is full of information. One thing that puzzles me is that most of the people who appear to be real "experts" here seem to all say their railroad is 1.20.3. I understand what this means except it seems that only Bachmann and some live steamers make 1.20.3. Isn't this limiting as far as choice? Is the quality of this size Bachmann up to the test? I have two LGB loco's and am trying to decide what to add next as far as loco's and rolling stock yet I see all this about 1.20.3? What's up with this?
