I have modeled in N, HO & 0 scale and now am going to try my hand at G scale. However I am a little confused at the different scales associated with G scale railroading! In researching G scale I have found that there are primarily 4 distinct scales used by the different manufacturers of G scale equipment, Aristocraft and USA trains are listed as 1:29 scale, Bachman is listed as 1:22.5 scale, LGB is listed as 1:24 scale and their is also a 1:32 scale. As I see it Aristocraft and USA trains will interchange on one anothers track but they will not interchange with Bachman, LGB or the 1:32 track and vice-versa, so I believe that if I start a layout I had better stick with the Aristocraft and USA trains and track since they are both 1:29 scale and will run on either track and they both have a large variety of loco and rolling stock to choose from. I really need help with as this is somewhat confusing to me, am I wrong about the different scales and track interchangeability. HELP!
