Model Train Gauges
Model Train gauges vary from the smallest, Z, to the largest, G (Garden) scale. Not shown on this chart is S scale. My backyard layout is G scale (1:16). On a shelf under my bed I have an O scale (1:45) layout. Recently my dad & I took apart a large HO scale (1:87) table layout. We plan to use the parts to create a brand new permanent layout in a different room.
