Les différentes échelles
The differents scales
Scale: The proportion that the model bears to the
full size prototype - can be expressed either as size relationship (1":1ft)
or a ratio (1:12, 1/12). Check the page of
definitions for more details.
Échelle: La proportion entre le modèle
réduit et le train pleine grandeur. Peut être exprimée
en relation (1":1ft) ou en ratio (1:12 ou 1/12). Consultez
la page des termes pour en savoir plus.
Gauge: The distance between the rails - generally
inside rail to inside rail. Check the page
of definitions for more details.
Écartement: La distance entre les deux rails,
de l'intérieur d'un rail à l'intérieur de l'autre rail.
Consultez la page des termes pour en savoir
plus.

P4 |
Britain |
18.82mm |
4mm:1ft, 1:76.2 |
P4 or Protofour was a radical rethink created by scaling down from the prototype
and increasing tolerances by the minimum neccessary for practical production
of components. It created quite a stir in 1966/67 but is now very well established.
P4 standards are also used for modelling Irish Railways broad and Narrow
gauges, using 21mm and 12mm gauges. And for modelling the GWR Broad gauge
using 28mm gauge |
