This is the scale which MOROP has defined for O scale, because it is half the size of the 1:22.5 Scale G-gauge model railways made by German manufacturers. [citation needed] 1:43.5: 7.02 mm: Model railways (0) Exact O scale of 7 mm = 1 foot. 1:43: 7.088 mm: Die-cast cars: Still the most popular scale for die-cast cars worldwide, metric or ...
1:48 1⁄4" scale used for Queensland sugar cane railways[17] and US subjects[18] of 3 ft 6 in. (1,067 mm) ^ O21 – [1] 3 ft (914 mm) ^ O16.5 – UK 7 mm scale with 00 16.5 mm gauge, used to model gauges between 2 ft (610 mm) and 2 ft 6 in (762 mm). ^ O14 – Finescale modelling of British 2ft gauge using 7 mm O scale and a unique 14 mm gauge.
1:22.6. 2 + 1⁄2 in (64 mm) The smallest scale able to pull real passengers. Was one of the first popular live steam gauges, developed in England in the early 1900s. In terms of model railway operation, gauge 3 is the largest (standard gauge) scenic railway modelling scale, using a scale of 13.5 mm to the foot.
The dominant scale used in the United States for models of "standard gauge" trains running on 45 mm (1.772 in) track, even though 1:32 is more prototypically correct. 1:29 represents standard gauge using 2 in (50.8 mm) gauge track, the original gauge 2. This fell into disuse as gauge 1 at 1.75 inch was very close.
The British version continued the pattern of sub-contracting to Germans, so, at 7 mm to the foot, it works out to a scale of 1:43.5. Later, the European authority of model railroad firms MOROP declared that the "O" gauge (still 32 mm) must use the scale of 1:45, to allow wheel, tire, and splasher clearance for smaller than realistic curved ...
The scale ratio of a model represents the proportional ratio of a linear dimension of the model to the same feature of the original. Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. [1] In such cases the scale is dimensionless and exact throughout the model or drawing.
The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres ( 1 100 m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.
Another popular scale is 1/72 or 1 inch equals 6 foot which uses 20 mm, to 25 mm miniatures. It is mostly used for historical gaming in part due to a wide selection of 1/72 scale models. Figures are commonly used with a variety of scales. It is not uncommon for there to be a mismatch between the game scale and miniature size.
