    I want to model the new Norfolk Southern F9A/F7B set, but I can only find F7As. What is the visible difference between them if any. The most I can find is a difference in engine and interior stuff. Thanks

    Check out the October 2006 issue of Model Railroader; there is an article on page 60 that is a guide of F units. Hope this helps.

    The F9 has an extra louver in front of the first porthole.

    The new NS Fs have been rebuilt, so they'll require some detail modifications from any commercial model. They'll need recessed ditchlights as seen here http://www.railpictures.net/viewphoto.php?id=181486 It appears that the louver in front of the porthole has been removed!

    Why not start with a Genesis or Stewart F9?

    IIRC, the F7-F9 development was a gradual morphing. Bits of detail on the body would be changed, then at one point the intenals were changed but the same bodywork was used (they had them in stock) and then the bodywork changed some more.
    I think the same applied to the GP models.
