| ZZ scale | |
|---|---|
| Scale ratio | 1:300 |
| Model gauge | 4.8 mm (0.189 in) |
| Prototype gauge | 1,435 mm (4 ft 8+1⁄2 in) standard gauge |
ZZ scale[1] (1:300) is a model railroad scale with a standard gauge of 4.8 mm (0.189 in). Models for the scale were produced exclusively by Bandai between 2005 and 2007. They depict Japanese prototypes such as Shinkansen trains. To date, no other traditional scale railway support exists for the scale. However the field of miniature war games has a large selection of buildings, trucks and other accessories at 1:285 scale and 1:300. Several suppliers make these in painted and unpainted form, and at several levels of quality.
Until the 2006 announcement of T scale, ZZ scale was the smallest commercially available scale for model railroads.
The following is the complete list of model trains released by Bandai for the 1:300 ZZ scale line, categorized by their release wave.
Active manufacturing of the first wave commenced in late September 2005, serving as Bandai's commercial launch of the 4.8mm gauge line.[2]
The second and final wave transitioned away from bullet trains to standard regional and commuter lines, launching in mid-April 2006.[4]

The Dalecarlian alphabet consists of 32 letters, 25 derived from the Swedish alphabet, and seven additional letters: vowels with an ogonek diacritic, denoting nasality: (Ąą, Ęę, Įį, Ųų, Y̨y̨, and Ą̊ą̊) as well as the consonant Ðð (eð), denoting voiced dental fricative, as 'th' in 'father'. The letters Cc, Qq, Xx and Zz are only used in names and foreign words. The alphabet is used for Elfdalian and for other Dalecarlian dialects. The language up until recently and on a small scale today is written with Dalecarlian runes.
A scale model is a physical model that is geometrically similar to an object (known as the prototype). Scale models are generally smaller than large prototypes such as vehicles, buildings, or people; but may be larger than small prototypes such as anatomical structures or subatomic particles. Models built to the same scale as the prototype are called mockups. Scale models are used as tools in engineering design and testing, promotion and sales, filmmaking special effects, military strategy, and hobbies such as rail transport modeling, wargaming and racing; and as toys. Model building is also pursued as a hobby for the sake of artisanship. Scale models are constructed of plastic, wood, or metal. They are usually painted with enamel, lacquer, or acrylics. Model prototypes include all types of vehicles (railroad trains, cars, trucks, military vehicles, aircraft, and spacecraft), buildings, people, and science fiction themes (spaceships and robots).
The Toyota ZZ engine family is a straight-4 piston engine series. The ZZ series uses a die-cast aluminium engine block with thin press-fit cast iron cylinder liners, aluminium DOHC 4-valve cylinder heads, and chain-driven camshafts. The ZZ family replaced the extremely popular cast-iron block 4A and 7A engines of the preceding A family of engines. The two 1.8 L members of the family, the 1ZZ and 2ZZ, use different bore and stroke. The former was optimised for economy, with torque emphasised in lower revolutions per minute operating range, while the latter is a "square" design optimised for high-RPM torque, yielding higher peak power.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
