European model railroad standards
The standards of European model railways , abbreviated NEM , are a work of standards, recommendations and documentation for model railways . They are worked out, defined, updated and also published by the Technical Commission , abbreviated to TK, the Association of Model Railroaders and Railway Friends of Europe , abbreviated to MOROP, which consists of a few people, including individual representatives of manufacturers and suppliers from the model railway industry.
application
Neither the standards nor the recommendations and documentation are binding on manufacturers and suppliers. However, they allow manufacturers and suppliers of toy and model railways to design their products in such a way that they function reliably with one another. They therefore adhere to the relevant points to ensure the compatibility of the products. However, manufacturers and suppliers must also take into account other points in this regard, such as the traditionally narrow radii of home systems, or the conditions on other continents, which we also have to take into account on a topic-related basis.
The standards define u. A. the standards for model railways . Recommend track radii and gradients, wheel profiles, couplings and also the data signal of the Digital Command Control . The standards cover a similar area as the standards and recommendations of the National Model Railroad Association (NMRA) in the United States or the documents of the British Railway Modeling Standards Bureau (BSRM) in the United Kingdom. However, the standards do not guarantee interoperability in all areas .
When standardizing the Digital Command Control (DCC), MOROP and NMRA worked more closely together, including with the manufacturers of the time.
Manufacturers and suppliers usually take into account the standards, recommendations and documentation according to NEM for products based on continental European models, while manufacturers and suppliers of products based on North American models generally follow the standards of the NMRA. The same applies mutatis mutandis to products based on models in Great Britain and the Commonwealth .
history
Just a few years after MOROP was founded, in the 1950s, the most important basics had been worked out. This mostly on the basis of company standards of the model railway manufacturers at the time or, for example, with regard to Switzerland, of standards established by the model railway associations of the time in the 1930s.
In the 1980s and 1990s, further standards and recommendations related to digitally controlled model railways , modular construction and the epochs were added. Both in the creation of the standards and recommendations for the digitally controlled model railways, as well as the modular construction, company standards and module systems used by individual clubs and groups were essentially documented.
Since the 1990s, MOROP has not provided any decisive impulses on the subject of standards, recommendations and documentation.
Standards, recommendations and documentation
There are three types of documents:
- Norms, abbreviated N
- Recommendations, abbreviated E
- Documentation, abbreviated to D
Order system
The NEM are identified according to a three-digit number system, some are also provided with a country code.
