And of course as one learns in model railroading the cube law means you need larger than scale flanges. As to curves, the last large layout I was involved with (in HO) used eased 48" radius curves. The "easing" was done using the formulae in a manual from the railway engineers assn. Long strings of full length (85') passenger cars, or autoracks and hi-cube auto parts boxes were operated flawlessly. This was a significant improvement over the un eased 36' curves of the previous setup. |
