    anybody know where i can find a bridge set w/ a 19'' radius curve on it?

    When you talk about a "bridge set" do you mean an "under & over" set up with trestles and a bridge at the top (such as Atlas has)? If so, I think you're fresh out of luck. Sectional track generally comes in even number radii, 18", 20", 22", etc. If not, you can use flex track & a supporting system of your own devicing.
    Good luck!!

    Except for stone viaducts or similar, all prototype bridges are made up of straight segments. If the track needs to be curved on the bridge, the segments meet at an angle.

    In model work, our curves tend to be much sharper than the prototype so the angles between segments are much greater, and don't look as good. Ways around that are to use bridges with short segments such as wood trestles. Another solution is to have the track curve through a widened bridge. This is a good solution as long as the widening is not too extreme and/or the viewer has difficulty seeing just how wide the bridge is.

    Hope this helps

    ...in HO. In N, 9.75", 11" and 19" are the most common sectional radii.
