HOn30
Encyclopedia : H : HO : HON : HOn30
HOn30 is a model railroading scale and gauge combination that uses HO scale models running on 9 mm gauge track. This represents 30 in. gauge narrow gauge railroads. This combination is sometimes known as HOn2½.
HOn30 is generally used when modelling American prototypes. In Europe this scale/gauge combination is known as HOe.
Although HOn30 acurrately models 30 in. gauge, in practice it is used to model gauges between 24 in. and 30 in.
The following table lists other combinations that are close to HOn30 in either scale or gauge;
| Name | Scale | Gauge | Prototype gauge | Description |
|---|---|---|---|---|
| 009 | 4 mm/foot | 9 mm | 2 ft 3 in (686 mm) gauge | popular in the UK |
| 00n12 | 4 mm/foot | 12 mm | 3 ft (914 mm) gauge | |
| HOn3 | 3.5 mm/foot | 10.5 mm | 3 ft (914 mm) gauge | mainly in US |
| Sn2 | 4.8 mm/foot | 9mm or 10.5 mm | Used for 2 ft (610 mm) gauge prototypes | |
| HOm | 3.5 mm | 12 mm | Used in Europe to model 1m (3 ft 3 in) gauge. | |
