Finescale standard
The term Finescale several standards for model railroads are summarized, which are compared with the usual NEM standards the model in more detail. The term is often used in conjunction with the wheel-rail system, as likely to affect such changes in this area of interoperability. However, far-reaching changes in all model bahne generic areas are needed to ensure the technical function and to provide a unified appearance.
Coarsening compared to the model
For model railway vehicles, the technical functionality is often the exemplarity in the way. This is due to the fact that can not be physical quantities and laws mitverkleinern. In addition, the radii of the tracks of a model railway are typically disproportionately smaller than the corresponding model radii, which they sought to compensate with larger wheels, especially larger wheel flanges.
Since the model train is increasingly viewed as a model and less than a toy, and the coarse wheels stand in stark contrast to the finer details of the other models, there are efforts to increase the exemplarity in this area. In German-speaking countries, this is summarized by the slogan "Down from the high rail " because Flanges force with a larger radius, correspondingly coarser rail profiles. It has been shown that when properly handled with the models, many of the previously practiced coarsening are unnecessary.
Finescale standards in nominal size H0
In the nominal size H0 several finescale standards for wheel sets, the different stages of maturity exist. A good reference point provides thereby the height of the flange, as this allows the naked eye an easy classification. In the NEM 310 is set at 0.6-1.2 mm, and large-scale manufacturers mainly exploit the top. The other dimensions of the wheels vary depending on the standard, so the wheel widths are about 2.8 to 1.49 mm.
The term is commonly applied to finescale everything to scale (read: better) than the NEM standard. This starts with RP -25 wheels according to the standard of the NMRA, which are 0.64 mm flange height is actually about the NEM minimum.
The model really come close to doing only standards such as Proto: 87, H0Pur or H0 finescale, all with about 0.3 mm flange height. Exact model would be a measure of 0.28 mm.
Finescale standards in other gauges
While larger H0 consist in nominal sizes have long been Finescale standards are available in nominal size N under the heading of fine scale since 1992 in FREMO efforts to refine the track rail system. From this FREMO grouping the desire to vehicles, in particular the wheelsets was to further refine and thus to achieve a better role model. The wheel / rail geometry is therefore not compatible with NEM. This is especially true for the groove width of the handlebars and heart pieces in turnouts. The tracks and many vehicles arising in DIY or rebuilt accordingly. Driving is on code 40 or even finer tracks with digitally -controlled vehicles. The couplings are not NEM - compliant because the vehicles with the scale-like magnetic -field coupling (MLC ) are equipped. With this coupling only prototypical radii can be driven. When modular real role models are preferably reacted.
Other consequences
Not only can not drive on tracks which are designed for vehicles with finescale wheels, but on the contrary require this larger curve radii and smaller core of vulnerabilities, so they often can not drive on the track material from large-scale series production vehicles with the usual non-precious metal wheelsets. This makes it clear that the higher exemplarity extends not only to the wheels or the wheel flange height, but virtually covers all areas of model railroading. To draw finer wheels the possibility of further refinements to the vehicles by themselves, especially in narrow wheelbases or engines of locomotives. Tracks and track environment can be made more realistic, so that ultimately loses the model train as a whole any toy character.
