Reply to "Back to basics...O Gauge"

So correct me if I am ms-understanding this proportion stuff:

If I assume MTH/Ross etc follows "Lionel standard" of 1.25" gauge from inside rail to inside rail, and real world 1:1 straight track gauge is 4'8.5" (56.5 ") inside rail to inside rail, then I calculated 56.5"/1.25" = 45.2. So wouldn't scale be 1:45.2 to make engine and cars exactly fit Lionel O gauge track? I know that 1:1 engines and car wheels are set at 56", give or take, to insure no tight track problems.
