Nominal size N

Excerpt from a diorama in N gauge in January 2011. Model of a class 64 steam locomotive from Minitrix and a B3yg DB conversion car from Roco.
NS DH2 in the scale 1: 160 and Kato Bernina Express in the scale 1: 150, both in the nominal size N, on tracks of the N gauge, with a model gauge of 9 mm, compared with a euro coin in size.

The nominal size N is a size for model railways standardized in the standards of European model railways (NEM) and the standards of the National Model Railroad Association (NMRA) . The normal gauge , with a track width of the prototype of 1435 mm, has a track width of the model of 9 mm and is colloquially referred to as N gauge. The scale is usually 1: 160. The nominal size is thus between the nominal size Z with a scale of 1: 220 and the nominal size TT with a scale of 1: 120. It is only about half the size of the currently most common nominal size H0 with a scale of 1:87.

history

According to some motorized and non-motorized model railway systems of similar size, e.g. B. from Kersting Modellwerkstätten GmbH (gauge K, model gauge 8 mm, scale 1: 180, 1948), Trix ( sliding trix , scale 1: 180, 1959) or Arnold ( Arnold Rapido 200 , scale 1: 200, 1960) the latter company established the still valid scale of 1: 160 in 1962. In 1964 the gauge was standardized internationally, for example in the NEM 010 standard , and was given the scale abbreviation N , as the number nine (for the model gauge of 9 mm) begins with an N in many languages . A standardized claw coupling was also specified in the NEM 356 standard, which allows vehicles from all manufacturers to be mixed in a train composition without modification . In the same year, Trix and the former GDR- based manufacturer Piko also offered models of this scale for the first time. Numerous other manufacturers worldwide followed and made the N gauge, after H0, the second most widespread internationally. In 2013, KATO surprised people at the Nuremberg Toy Fair with a Glacier Express in the standard scale of 1: 150 for cape gauge models in Japan , and for N gauge with a model gauge of 9 mm.

Gauges

Continental Europe

For the nominal size N, the following model gauges are specified in continental Europe on a scale of 1: 160 in the European Model Railways (NEM) standards:

track designation Model gauge Prototype gauge Use with prototype gauges
N Standard gauge 9 mm 1435 mm from 1250 mm to 1700 mm
Nm Meter gauge 6.5 mm 1000 mm from 850 mm to <1250 mm
No Narrow gauge 4.5 mm 0750 mm, 760 mm and 800 mm from 650 mm to <850 mm
  • Ni (Nf): The model gauge of 3.75 mm (field and industrial prototype gauge from 400–650 mm) is not standardized, but defined for the first time by Railino . This model gauge is only produced by small series manufacturers.

North America

For the nominal size N, the following model gauges are specified in North America at a scale of 1: 160 in the standards of the National Model Railroad Association (NMRA):

track designation Model gauge Prototype gauge
N Standard gauge 9 mm 1435 mm (4 feet 8½ inches )
Nn3 Narrow gauge 6.5 mm 0914 mm (3 feet)
Nn2 Narrow gauge 4.5 mm 0762 mm (2½ feet)

Deviations in scale

In deviation from the international standard, the scale of the nominal size N is 1: 148 in Great Britain and 1: 150 in Japan . The standard gauge is also simulated with a model gauge of 9 mm.
