The difference between scale and gauge in model railway is that scale refers to the size of the model in relation to the real world, while gauge refers to the distance between the rails of the track.
Scale
Scale is a ratio that compares the size of a model to the size of the real object it represents. For example, a model train in 1:76 scale is 1/76th the size of a real train. This scale can also be stated as 4mm to the foot.
Gauge
Gauge is the distance between the rails of a railway track. The most common gauge in the world is standard gauge, which is 4 feet 8.5 inches wide. Other common gauges include narrow gauge, which is less than 4 feet wide, and broad gauge, which is wider than 4 feet.
Choosing a Scale and Gauge
When choosing a scale and gauge for a model railway, there are a few factors to consider. The first factor is the size of the space available for the layout. Smaller scales, such as OO scale and N scale, are better suited for smaller layouts, while larger scales, such as G scale and O scale, are better suited for larger layouts.
The second factor to consider is the type of trains that you want to run on your layout. Some scales, such as OO scale and N scale, have a wide variety of trains available, while other scales, such as G scale and O scale, have a more limited selection of trains.
The third factor to consider is your budget. Smaller scales, such as OO scale and N scale, are generally less expensive than larger scales, such as G scale and O scale.
Popular Scales and Gauges
Some of the most popular scales and gauges for model railways include:
- HO scale: 1:87 scale with a gauge of 16.5 millimeters
- OO scale:1:76 scale with a gauge of 16.5 millimeters
- N scale: 1:160 scale with a gauge of 9 millimeters
- O scale: 1:48 scale with a gauge of 32 millimeters
- G scale: 1:22.5 scale with a gauge of 45 millimeters
These are just a few of the many scales and gauges available for model railways. The best scale and gauge for you will depend on your individual needs and preferences.
