Model Train Layout Considerations

If you are considering building a model train layout, watch this video. Il discuss curves, grades and many other bits of vital layout knowledge and experience. Step by step building a model train layout. In North America, equipment for unlimited interchange between railway companies is built to accommodate for a 288-foot (87.8 m) radius, but normally a 410-foot (125.0 m) radius is used as a minimum, as some freight carriages (freight cars) are handled by special agreement between railways that cannot take the sharper curvature. For the handling of long freight trains, a minimum 574-foot (175.0 m) radius is preferred.[3] Link to Wiki https://en.wikipedia.org/wiki/Minimum... To translate that into model railway terms, 288 feet becomes 3’ - 3 ¾” or 1.09 m in HO Scale 410 feet becomes 4’ – 8 ½” or 56.5 inches or 1.436 m in HO scale I did not calculate 574 feet
