    Has anyone tried modeling broad gauge in N?
    There are a range of possibles: 5'3", 5'6", 7'0.25" etc.
    The last of these (e.g. Brunel's 7 foot broad gauge in England) would look most impressive...!

    HOn3 track, at 10.5mm gauge, scales to 5'6" in N. Great Western broad gauge would require 13.38mm gauge, or 14.86mm if you're using the British value of 1/144 for N.

    Modeling broad gauge in almost any common scale requires building just about every critical item for an operational model railroad from scratch - locomotive mechanisms, track, trucks and wheel sets. That's why most folks going after an unusual prototype gauge will pick a functional gauge, and actually adapt the scale to suit the gauge.

    The best example of this practice is G. The G gauge is the common track gauge for a number of different scales to represent various prototype gauges using the same model gauge. At 1/32, G gauge is correct for standard gauge track. LBG used 1/22.5 on the same track to represent European meter gauge. And a sizeable contingent (including Bachmann) uses 1/20.3 to use G track to correctly represent 3ft gauge. Interestingly enough, G track would be just about spot on for your 7ft broad gauge in O (1/4") scale.

    The closest bigger track gauge to N with any commercial support is HOn3 at 10.5mm gauge. At 1/160 scale, 10.5mm represents 5ft 6" gauge quite accurately. The HOn3 wheels would probably not be too grossly oversize for N scale broad gauge, so this might be a workable combination. I don't see any other viable combinations in N scale. Sn3 track, the next commercial gauge up, would be 90" or 7.5ft. And the Sn3 wheel sets would be huge in N scale.

    my thoughts, your choices
