S scale never was. 5.5*64=352mm, or about 14". Unless you're referring to another foul-up of scale and gauge induced by sleepwalking followers of Henry Greenley.
Standard gauge in S scale is 22.4mm +/- the usual tolerances.
HTH
Except that 5.5mm to the foot is not S Scale, S Scale is 1:64
5.5 mm is an example of a made up scale specifically to suit the track gaugeAlso Sn3 does not use H0 track, what was meant was Sn3.5 for 3ft 6in gauge. Sn3 will be found detailed in the nmra standards and uses a gauge of 14.3mm.

GAAAH! Another one of those furshlugginer "rounding offs" that you Brits are addicted to. Wotthe'ell do you guys smoke when you're setting standards?????
S is 1/64th scale. 1ft is 304.8mm. 1/64 of 304.8mm is 4.7625mm. If you don't like mm, use 3/16" - it's exactly 1/64 of 12 inches.
Sheesh!
Christopher,
S scale, at 3/16" : ft is close to 4.7mm:ft, which gives a track gauge very close to 16.5mm for 3' 6" gauge. Granted that the people in N. America use Sn3 to model their 3' gauge lines but that is just over 2mm over gauge for their prototypes.
Jim.
Nigel,
I wasn't sure whether you were being UK-centric or global :-)
Jim.
Surely, Wolf, it's 28.3 inches and thus nearer to 2ft 3inch gauge, EM would be 2ft 6in; though narrow gauge locos are generally sufficiently simple below the running plate to allow over-gauging.
Ken.
Christopher,
That was historic. S scale started as Half-One scale pre-WW2 and was either 5mm:ft or 3/16":ft depending on whether you considered Gauge One to be 10mm:ft of 3/8":ft. However, S scale in N. America was 3/16":ft from the start.
The Scale/Gauge had been called H1 in the UK, but after the was it was decided to change to the N. American name of S to avoid confusion with a commercial company trading under the H1 name. At the same time, it was decided to adopt only the more accurate imperial scale of 3/16":ft. At the time a society called the S Gauge Model Railway Association was set up to support the gauge and this Association (now the S Scale MRA) is the oldest specialist scale society in the UK, and possibly the world. It is also, possibly, the first society to draw up accurate scale/gauge standards, beating the Protofour people by a year or two.
Jim.
Jim, Go back to my last posting, those folks in N America use the correct
9/16 gauge for Sn3. KeithKeith,
Sorry - I was getting my Sn3.5 and Sn3 mixed up. Yep, the 3' gauge people use 9/16" gauge :-)
Jim.
You're right. I had it confused with On30. But I believe another poster mentioned that it is used in S scale for 3'6" gauge. To quote:
Wolf's 31.7" is On30 - 1/4" scale (or 1:48) running on 16.5mm track as opposed to 0-16.5 which is 7mm/foot (1:43.5) on the same 16.5mm gauge track, and scales out at 28.3" or so...
So many scales, so many gauges...

Do you guys really say 'furshlugginer'? I thought it was just a word invented by Mad magazine.
John
Quite, that was what started the need for corrections, the error in that paragraph was to call it Sn3 when it should be Sn3.5 Maybe we should drop it now! Keith
Larry,
My mistake in that message - should have said Sn3.5 using H0 track under S scale superstructures.
Jim.
Sn3 is 14.25mm gauge, not 26.5 mm. The latter would be Sn42 or Sn3-1/2.
Uh, oh, you're using 1:43, not 1:48... which is what we use over here for O scale.
Yup, and a vey handy word it is, too. :-)
OOPS, that should be 16.5, not 26.5mm. Furshlugginer keyboard...!
Surely this topic is now worthy of a television documentary, where we can explain to the audience how this is really, really, important!
Cheers, Steve
