Proto scale was originally developed by the Model Railway Study Group in Great Britain in 1966 and later adopted into NMRA standards with modifications necessary for the North American prototype railway standards. Proto scale reproduces faithfully the prototype wheel tread profile and track work used by the Association of American Railroads and ...
This scale is today the most popular modelling scale in the UK, although it once had some following in the US (on 19 mm / 0.748 in gauge track) before World War II. 00 or "Double-Oh", together with EM gauge and P4 standards are all to 4 mm scale as the scale is the same, but the track standards are incompatible. 00 uses the same track as HO (16 ...
Joe Brook Smith was the first to propose use of an exact scale track gauge in July 1964, when also the term Protofour was invented by Malcolm Cross. [2] The standards were later published in Model Railway News by the Model Railway Study Group in August 1966.
Most commercial scales have standards that include wheel flanges that are too deep, wheel treads that are too wide, and rail tracks that are too large. In H0 scale, the rail heights are codes 100, 87, 83, 70, 55, 53, and 40 -- the height in thousandths of an inch from base to railhead (so code 100 is a tenth of an inch and represents 156-pound ...
Railway modelling has long used a variety of scales and gauges to represent its models of real subjects. In most cases, gauge and scale are chosen together, so as to represent Stephenson standard gauge. By choosing a smaller gauge than this for a particular scale, the model represents a narrow-gauge example. [1] [2]
The NMRA is home of the A.C. Kalmbach Memorial Library, which houses model and prototype railroad books, periodicals, photos, videos, and reference materials, and was designated as the official railroad library of the state of Tennessee in 2004. [3] In 2013 the NMRA started the process of moving the library to the California State Railroad ...
