BP Chuck, I am afraid I am familiar only with the HO gauge having had such a layout in past years. I can only add that the gauge was one of the "larger" ones. The engines (locomotives) were about 12-18 inches long and the cars a little shorter than that, if this helps at all.
All buildings depicted exteriors only. I don't know the scale of the entire project but, to give you a feel for the size, if I were to stand next to one of the cathedrals - for example - it would rise about level with my waistline. "People" appearing in some of the displays such as Chateau de Versailles were approximately 6 inches tall.
To me one of the most charming features was the fact that all vegetation was (is) trimmed to approximately the same scale which blends beautifully in with the buildings and more or less screens one display from the one next to it.
Sorry to be so late with this reply. Best regards, Alex
