Standard Gauge, also known as wide gauge, was an early model railway and toy train rail gauge, introduced in the United States in 1906 by Lionel Corporation. [1] As it was a toy standard, rather than a scale modeling standard, the actual scale of Standard Gauge locomotives and rolling stock varied.
The NMRA published alternative, more accurate and realistic standards for track and wheels sheet in S-1.1 These model railway standards are based on the full size prototype standards and the scale model operational reliability is therefore reduced in comparison to the models conforming to the normal NMRA standards.
Alternatively 1.1/8 inch per foot is adopted, only Australia for ease of conversion. allowing a scale of 3/32 inch per full size inch. This results in an oversize locomotive and often negates building inside valve gear locomotives (such as the GWR King Class 4-6-0) due to frame width restrictions caused by 5 in ( 127 mm ) gauge track.
Ring sizes can be measured physically by a paper, plastic, or metal ring sizer (as a gauge) or by measuring the inner diameter of a ring that already fits. Ring sticks are tools used to measure the inner size of a ring, and are typically made from plastic, delrin , wood, aluminium, or of multiple materials.
The dominant European size for die-cast ship models, most comprehensive range. 1:1200: 0.01 0.254 mm: Ship models: A British and American size for ship and harbour models. Airfix used to produce in this scale. 1:1000: 0.305 mm This is a scale used in Germany for pre-finished airliner models. Herpa and Hogan Wings produces several models in this ...
The terms "scale" and "gauge" are often confused. Strictly speaking, scale is the ratio of the size of a model to that of its prototype and gauge is the distance between the track railheads. In the case of S scale, the proportion is 1:64 or 3 ⁄ 16 inch modeling 1 foot. Standard S gauge track has a spacing of 0.883–0.905 in (22.4–23.0 mm).
Lionel Corporation was an American toy manufacturer and holding company of retailers that was founded in 1900 and operated for more than 120 years. It started as an electrical novelties company. Lionel specialized in various products throughout its existence. Toy trains and model railroads were its main claim to fame. [1]
O scale (or O gauge) is a scale commonly used for toy trains and rail transport modelling.Introduced by German toy manufacturer Märklin around 1900, by the 1930s three-rail alternating current O gauge was the most common model railroad scale in the United States and remained so until the early 1960s.
