Model railway scales and gauges are standardized in NEM 010, [1] which covers several gauges for each scale. Narrow gauges are indicated by an additional letter added after the base scale as follows: no letter = standard gauge (1,250–1,700 mm or 49.2–66.9 in) m = metre gauge (850–1,250 mm or 33.5–49.2 in) e = narrow gauge (650–850 mm ...
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.
Dollhouse for a dollhouse scale for 1:12 dollhouses. Commonly used for mini armor. Used for 12 mm, and 12.5 mm figure scale miniature wargaming. 1:128: 3 ⁄ 32 in: 2.381 mm A few rockets and some fit-in-the-box aircraft are made to this size. 1:120: 0.1 in: 2.54 mm: Model railways (TT) Derived from the scale of 1 inch equals 10 feet.TT model ...
Standard gauge. OO gauge or OO scale (also, 00 gauge and 00 scale) is the most popular standard gauge model railway standard in the United Kingdom, [1] outside of which it is virtually unknown. OO gauge is one of several 4 mm-scale standards (4 mm to 1 ft (304.8 mm), or 1:76.2), and the only one to be marketed by major manufacturers.
A partially disassembled Curta calculator, showing the digit slides and the stepped drum behind them Curta Type I calculator, top view Curta Type I calculator, bottom view. The Curta is a hand-held mechanical calculator designed by Curt Herzstark. [1] It is known for its extremely compact design: a small cylinder that fits in the palm of the hand.
They have a range of car and city related sets that could be used as accessories for the wooden toy train ranges of other producers. They had a joint venture with Brio in 2001–2002, [28] being present in the Brio catalogs of the time. By 2007 they had started their own line of wooden trains, expanding it in 2008.
A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
1,435 mm (4 ft 8 + 1⁄2 in) standard gauge. 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.
