The width of the model railroad track, specifically referring to the distance between the rails (known as the gauge), varies depending on the scale of the model train. Based on the provided reference, the track gauge for HO model trains is .625″ wide.
The reference states: "The distance between the rails is called the gauge... In the model world, HO trains run on track gauge that is only . 625″ wide, scaled down from the real thing."
This .625 inch measurement represents the standard gauge for HO scale, which is one of the most popular model railroad scales. It is a scaled-down version of the real-world "standard gauge," which is four feet, eight and a half inches inside-to-inside between the rails.
Understanding gauge is crucial in model railroading as it determines the size of the trains and the track required. Different scales (like N scale, O scale, G scale) use different track gauges.
Here's a simple comparison based on the reference:
| Feature | Real-World Standard Gauge | HO Model Track Gauge |
|---|---|---|
| Measurement | 4 feet, 8.5 inches | .625 inches |
| Definition | Distance between rails | Distance between rails |
In summary, for HO scale model trains, the track has a specific width between the rails, which is the gauge, measuring .625″.
