Toy trains come in various sizes, primarily defined by their scale (proportion) and the gauge (width) of the track they run on.
Understanding Toy Train Sizes
The size of a toy train model is typically expressed as a scale, which is a ratio comparing the model's size to the real train. For instance, a 1:48 scale train is 1/48th the size of the actual locomotive. Alongside scale is the gauge, the measurement between the rails of the track. Certain scales are designed to run on specific track gauges.
According to the provided information, popular sizes include several scales that operate on the same track gauge:
| Scale (Proportion) | Common Name | Track Gauge | Gauge Measurement |
|---|---|---|---|
| 1:32 | Gauge 1 | 45mm | |
| 1:22.5 | G scale | Gauge 1 | 45mm |
| 1:20 | Gauge 1 | 45mm |
These models are offered in proportions such as 1:32, 1:22.5 (known as “G scale”), and 1:20. All of these scales operate on Gauge 1 track, which measures 45mm between the rails.
The reference also mentions the next largest popular scale is O (1:48 proportion). Trains in this scale use O gauge track, which measures 1¼ inches between the rails.
In summary, toy train sizes are defined by scales like 1:32, 1:22.5 (G scale), 1:20 (using Gauge 1 / 45mm track) and 1:48 (O scale) (using O gauge / 1¼" track), among others not listed in the reference.
