    hello all, im just wondering if anyone can help me out with this one. im currently working on an ho layout on the back of an old door thats 34" wide and about 7 ft long now my question is what kind of turnout could i use to maintain an inside curve of 15".

    That's tough. Atlas Snap-Switches have a continuous 18" curve. At least some #4s have a minimum 15" radius, but are straight beyond that. I doubt any American company makes a turnout with a continuous 15" diverging route. Some European manufacturers probably do.

    Sopunds like a job for flex track.

    You might find a tight-radius switch in a box of old track. I think Fleischman made them and possibly Hornby-Dublo. But these go back to the 60s and the flangeways are probably a bit wide.

    Peco makes a stub switch that might be easier to use.

    a standard #4 Atlas Custom line would probably be about 18 inch radius, but that would probably make a nice transition curve into a 15 inch. If your locomotives and rolling stock is small enough, you might be able to use flex track and reduce the radius to 12-14 inches in the center of the curve to make it fit the door if necessary. Most equipment will handle a short section of a tighter radius than they are designed to operate on continuously.
