NMRA standard S-1.2 covers the popular model railway scales and S-1.3 defines scales with deep flanges for model railways with very sharp curves or other garden railway specific design features. In certain NMRA scales an alternative designation is sometimes used corresponding the length of one prototype foot in scale either in millimetres or in ...
The NEM standards define the model railroad scales and guide manufacturers in creating compatible products and assist modellers in constructing model railroad layouts that operate reliably. The standards cover areas like suggested grades , turnout radii, wheel profiles, coupling designs and Digital Command Control (DCC) and are mostly scale ...
A Japanese H0e scale model railroad One of the smallest (Z scale, 1:220) placed on the buffer bar of one of the larger (live steam, 1:8) model locomotives HO scale (1:87) model of a North American center cab switcher shown with a pencil for size Z scale (1:220) scene of a 2-6-0 steam locomotive being turned. A scratch-built Russell snow plow is ...
A chloridometer is a measuring instrument used to determine the concentration of chloride ions (Cl –) in a solution.It uses a process known as coulometric titration or amperostatic coulometry, the accepted electrochemistry reference method to determine the concentration of chloride in biological fluids, including blood serum, blood plasma, urine, sweat, and cerebrospinal fluid.
Thus the scale and approximate prototype gauge are represented, with the model gauge used (9 mm for H0e gauge; 6.5 mm for H0f gauge) being implied. [2] The scales used include the general European modelling range of Z, N, TT, H0, 0 and also the large model engineering gauges of I to X, including 3 + 1 ⁄ 2, 5, 7 + 1 ⁄ 4 and 10 + 1 ⁄ 4-inch ...
Model Railroader publishes two annual special issues: Great Model Railroads showcases 10-12 spectacular model railroads, including large, inspirational photographs, detailed track plans, and how-to information. Model Railroad Planning deals with aspects of designing and constructing a model railroad. Typical articles focus on reproducing ...
Gn15 modeling is a relatively new phenomenon in the model railroading world. While the idea of this scale has existed for some time, as evidenced by the early efforts of Marc Horovitz, editor of Garden Railways magazine, Gn15 did not gain any measure of popularity until the Sidelines range of models.
T-TRAK (all letters capitalized) is a modular model railroad system based on standards for module size, track placement, track interface, and electrical connections. The standards allow for a wide range of flexibility in design yet still maintain interoperability with all modules built per the standards.
