I don't know the reason N scale was named that.
Bottom line is there's little science or consistency behind these names.
Great reference page thank you. So I found a RMT flat car I would like to aquire. Any idea how it will hold up next to Lionel traditional?
Like I alway say.........No matter what scale.......THEY ARE ALL TOYS.I love O and O-27 simpley due the all the action accesory buildings/ industries. However I feel I would have a hard time making it all to scale like I did with my HO layout. Instead of making it realistic I may make it the Toy Train Layout.
Fair enough.Sometimes the trucks don't have the clearance to swivel sufficiently for O27 curves, that would be the normal reason for that restriction.
