Why does the term N scale wind me up so much? It has always been N gauge in this country.
Agreed. I tend to unconsciously translate 'N Scale' as meaning 1:160 à la US and Continental.
Can't say it winds me up though. Does make me envious, :drool: of some of kit available due to the larger market.
I think it is the way Farish have switched to using the term. N 'scale' makes no sense.
They actually changed it to 'scale' on their 2008 catalogue, so I have had nearly a decade to get riled.

So if we're talking about the misuse of 'N Scale' when talking about 'N Gauge' then I'm in full agreement with you @Elvinley (http://www.ngaugeforum.co.uk/SMFN/index.php?action=profile;u=268) - that does wind me up! :veryangry: :censored: :veryangry:
"N" as we use (or abuse) it refers to a specific combination (or rather three geographically distinct combinations) of Model to Prototype Linear Dimension Ratio (what we call Scale) and model track Gauge.
As those three geographically distinct combinations of Scale and Gauge share a common Gauge, "N-Gauge" is acceptable and valid as an overarching descriptive term. "N-Scale" is not, though perhaps "British N-Scale","German N-Scale" (yes - Arnold first used the 1:160 ratio not the Yanks ;) ) & "Japanese N-Scale" are meaningful and so tolerable...
Contrast that to the big boys who have 00, EM and P4 with a common scale but different gauges - "00-gauge"/"EM Gauge"/"P4 Gauge" are valid terms "00-Scale"/"EM-Scale" absolutely isn't, otherwise a "EM-gauge" model could also be labelled "00-Scale" :doh:
And what about "009" Narrow Gauge modellers?? their models share that "N-Gauge" but are most definitely not "N-Scale" and although they share a common Scale with "00"/"EM"/"P4" they are not "00-gauge"/"EM Gauge"/"P4 Gauge". :hmmm:
In the real world; Call it whatever you like... Doesn't really matter... we'll know what you mean, though some pedant will always quibble... ::)
Oh, now I don't know if I'm wound up, a pedant, or just tired. ??? I'll sleep on it a while. :sleep: ;)

Couldn't agree more Sir. In keeping with that tone, here we go ...
There was once a young man who loved N-Gauge
Who found himself in a rage
He beat his brow
Wouldn't accept N-Scale
And his complaint found it's way to this page!
:ban:
You didn't make that up, did you. If you did, it's pistols at dawn ;D
Thought I'd bring some light-hearted jest to the thread. On a far more serious note - I too prefer N-Gauge to N-Scale.
After a reflective night in :sleep: scale land, I've decided to pack in N and start modelling 1:1 scale. :laugh3:
Or is it 4' 8½" gauge? ;)

And so Ndeth the lesson. Amen, brethren.

As someone who models in 1/160, 1/148 and 1/150 I find myself using N on its own without the gauge or scale qualifier. After all is N Gauge appropriate for a scenic item where track gauge is irrelevant. Our close neighbours in France use N scale (Echelle N) and in Germany N track (Spur N).
Notice Oxford Diecast now uses 1/148 and N gauge, so maybe something where gauge is the right word in planning. :)

Whipping out my pedant hat, "Spur" is actually "gauge", as in "Breitspur", "Schmalspur" etcetera.

I was mistranslating "spur" as in "spurbreite". But I must admit that German was not my strongest language in spite of running two railway wagon facilities in Austria and Germany. :)

I never did understand 2mm scale unless it's entirely scratch built. Allot of effort put into track, re-wheeling and gauging, but then you accept (in the majority) an out of scale body and rolling stock of "N gauge"???? I take my hat off to 2mm scale modellers though -allot of effort involved which is entirely correct, but I can't see standing at 1m / 3ft / 1 yd back!

Calm down dear.....it's only a commercial!

I had always understood that N gauge scale/gauge came out as;
N=Nine millimetre (the track gauge used).
Scale-the scale of the trains running on said 9 mm track.
I prefer N-gauge, with the scale unsaid.

...'N Scale' (universally interpreted to mean 1:160) when talking about 'N Gauge' (universally interpreted to mean 1:148)?[/i]".
Not sure I'd agree with "universally interpreted" for either of those two terms. "N gauge" certainly doesn't naturally equate to 1:148 for me, it has nothing to do with the scale other than there are a group of fairly close scales which happen to run on the same gauge, excluding the "obviously narrow gauge" larger scales such as HOe, 009 etc.
As a modeller of german railways since the 80s, if anything then "N Spur" / "N gauge" implies 1:160 scale to me and probably means 1:160 to rather more people worldwide than it means 1:148.
I tend to distinguish the scales as "European N Scale" = 1:160, "American N Scale" = 1:160, "British N Scale" = 1:148, "Japanese N Scale = 1:150".
I think Farish are right to use "British N Scale".
[edit]
btw, we have exactly the same
argument discussion on the large scale fora re "G Scale" or "G Gauge" which has a whole bunch of different scales running on the same track gauge.
[/edit]
What's with all this Johnny-come-lately N gauge/scale stuff anyway? Everyone knows it's really OOO.... :D
(OK, I admit it. I am old enough to have owned a Lone Star Treble-O-Lectric set many, many moons ago. And the push along die-cast stuff, which is still around somewhere. My son used to love playing with that. I wonder if my new grand-daughter will? )
OK - I'll get my coat. The white one, with the funny arms... ;)
For me it's simple:
I take 'scale' in this context to mean what many dictionaries define it as - the relation between the real size of something and its size on a map, model, or diagram. Hence we have 1:148, 1/150, and 1/160 for the scale of the models that we are using and/or modelling.
'Gauge' is a noun in this context that denotes the distance between the track rails. It is a fixed measure, not a variable, as 'scale' can be as it describes a ratio.
The meaning of 'N' is less clear to me: nine or neun for the 9mm track width; Nuremberg (home of the Arnold company, often credited with the modern commercial origin of the hobby); or any number of the alternative interpretations that abound ('nerd' was one unkind alternative I came across :D)
So for we 'N' hobbyists/modellers/enthusiasts who choose to create or operate in various scales, for me there is only one term that encompasses us all, and it is the one that denotes the rails we all run our variously scaled trains upon: N Gauge.
That's how I consider it anyway, and if others have differing views then that's fine.
Not that it really matters. :D

British N Fail may be more appropriate with the lack of QC and silly prices.
Hello.
The debate on N scale vs. N gauge is really interesting, not to say it is fun to have it.
Of course, it doesn't matter at all in the end.
First, N is for nine in German. This is what it means.
So it lets us think that N refers to the gauge, i.e. 9mm.
We need also to take into account that the scale may differ from one region to another.
So 'N' can be defined as modelling standard 1435mm gauge railways with autopropelled locomotives running over 9mm gauge tracks and produced in series.
Unfortunately, we have all these suffixes...
- 'Nm' to model metre gauge with Z tracks
- 'Nn30' ('Ne' could apply but this is not used) to model 30in gauge with 4.5mm tracks
- 'Nf' ('Nn18' could also apply but again not used) to model 50cm or 18in gauge with T tracks
And as far as I know it is always in 1:160.
We have the same with HO: HOm, HOn3, HOe / HOn30, HOn2 / HOf and even HOn15.
So this goes in favour of considering N as a scale.
This would mean, we need to distinguish 'continental N scale', 1:160, and 'British N scale', 1:148.
Some further thoughts.
What about modelling Japanese or Australian trains?
High-speed lines in Japan use the standard gauge, i.e. 1435mm. It is modelled in 1:160 using 9mm gauge tracks. It is part of the continental N scale family.
Apart high-speed lines, most Japanese and Australian lines use the 1067mm gauge, which is a narrow gauge compared to the standard one.
If you want to model 1067mm gauge at 1:150, then you should use 7.1mm gauge tracks. The closest thing to that is Z tracks. This is named 'Nj'. ('Nm' is for modelling 1m gauge at 1:160 using Z tracks, slightly different.)
If you want to model 1067mm gauge using 9mm gauge tracks, then you should use TT scale. And you get 'TT9', 1:120 over 9mm gauge, which is used in Australia. It could also be named 'TTj' but this is not used.
It appears the N Japanese market offers 1:150 model trains running over 9mm gauge tracks to model Japanese 1067mm gauge and Swiss RhB metre gauge railways. This is 'Japanese N scale', but opposite to continental and British N scales it doesn't model standard gauge railways. So it's not a "true" N scale, based on the definition above. :doh:
To summarize:
- 'continental N scale' is for 1:160 over N tracks to model standard gauge railways
- 'British N scale' is for 1:148 over N tracks to model standard gauge railways
- 'TT9' is for 1:120 over N tracks to model 1067mm gauge railways
- 'Nj' is for 1:150 over Z tracks to model 1067mm gauge railways
- 'Nm' is for 1:160 over Z tracks to model metre gauge railways
- 'Japanese N scale' is for 1:150 over N tracks to model 1067mm or metre gauge railways
I hope you had fun reading this, without any headache. :dunce:
Again, it doesn't matter at the end, as long as we are N-thusiasts! :)

In order to give a greater headache, here are some tables listing all scales available for railway modelling.
This is something I did in early 2010 and this thread has encouraged me to update the lists.
First, we need to consider the suffixes added to the scale, which identifies the gauge modelled.
MOROP specifies the following ones:
(http://www.teatime.pm/public/Echelles/morop.png)
But this doesn't fully reflect all the diversity we have. So I prefer the table below:
(http://www.teatime.pm/public/Echelles/suffix.png)
* only the main narrow gauges are listed
Note also that 'j' and 'n3½' are specific to Japan, Australia, New-Zealand and South Africa.
Then, when you model standard gauge (1435 mm) railway, you have plenty of choices:
(http://www.teatime.pm/public/Echelles/standard.png)
If you model railway in Japan, Australia or New-Zealand (i.e. 3 ft 6 in or 1067 mm), then you have to select one of these to be accurate:
(http://www.teatime.pm/public/Echelles/japanese-1.png)
You can also select one of these two. They are less accurate but more "mass market":
(http://www.teatime.pm/public/Echelles/japanese-2.png)
Note: Japanese N is used by Kato for its famous RhB product line.
If you model metre or 3 ft gauge, then you have this long list:
(http://www.teatime.pm/public/Echelles/metre___3ft.png)
Notes:
- SM45 models 3 ft gauge.
- Nm is also referred as Nn3. But 6.5mm gauge is not so accurate for 3 ft gauge.
If you model 30 in, 76 cm or 75 cm gauge, then you have this other list:
(http://www.teatime.pm/public/Echelles/narrow.png)
Note: OO9 is best to model 2 ft 3 in (686 mm) gauge railway.
Narrower and narrower with 2 ft and 50 cm gauge railway:
(http://www.teatime.pm/public/Echelles/60___50_cm_gauges.png)
Notes:
- Using 9 mm gauge tracks for Sn2 is more accurate than 10.5 mm.
- OO6.5 is fine for 50 cm gauge.
- HOn2 can also use 7 mm gauge tracks.
And the most narrow you can find for 18 in and 15 in gauge railway:
(http://www.teatime.pm/public/Echelles/n18___n15.png)
Note: Instead of Gn15, we should say IIn15.
I must say that there is no product available for OO6.5, Zn2, HOn15 and TTn15.
I was really astonished to see they are so many different scales...

Only thing I know is that people who modelling between 1:148-1:160 are smart and good looking people.
Well made charts though.
