several folks here mentioned the over-size of Gargraves ties and tubular rails in general. Obviously, you cannot get a shrink ray and scale them down. However, you may ballast and do a great job with weathering and this will greatly assist in taking the focus away from the track!
The greatest compliment that I ever received about my track: Gargraves/Ross was from two Board Members of the Lionel Collector's Club of America. Both of these gentlemen said to me, after viewing the layout, at separate moments: "I thought this was a two rail track after seeing video/photos."
My "phantom" blackened center rail "disappears" into the ties and ballast below; which also make the rail look smaller.
NOTE: THIS DOES NOT WORK IN SNOW SCENES...the rail may appear smaller but the center rail is much easier to see against white snow!
