gauge one versus g scale

"They both run on 45 mm track. Gauge 1 is usually 1:32. "G" scale is a generic lable, but usually refers to LGB's 1:22.5. Although that is always debated".


Thanks Chuck for the information. So Gauge 1 or G scale are related to the ratio of the trains not the dimension of the rail. It's important to know that knowledge because I usually skipped any products listed as gauge 1 since I think they are unfit for my rail.

Are you referring to the Aster "Krauss Tank?" I think this is the only current Aster 0-4-0, and I believe it is (or is close to) the scale of LGB "G scale," e.g., 1:22.5

1 gauge represents standard gauge trains on 45 mm track, and this is 1:32 scale.

There is no description if it is a Krauss Tank but I searched around, it locos is old, it's back in 1976.

The below terms are in context to 45mm gauge track which we collectively refer to as 'Large scale'.

Gauge 1: 1.75" (44.45mm), Correct for standard gauge prototypes modeled in 1:32 scale.
G Scale: Originally termed by LGB, 'G' for 'gross' (big). Correct for 1 meter gauge European prototypes modeled in 1:22.5 scale. Called IIm in Europe (45mm gauge).
G Gauge: Misnomer but everyone knows what it means.
F Scale: or 'Fine Scale'. Correct for 3ft narrow gauge prototypes modeled in 1:20.3. 'Fn3' term is also used.
H Scale: Term not widely used but is 'Half inch' to the foot scale. Correct for 3'6" gauge (cape gauge) prototypes modeled in 1:24.
SE Scale: or 7/8" to the foot scale. Correct for 2' gauge prototypes modeled in 1:13.7 scale.
SM Scale: or 16mm to the foot scale: Correct for 2' gauge prototypes modeled in 1:19 running on 32mm gauge track 'SM32'. Often this scale is also run on 45mm track 'SM45'.
Gummy Scale: Often employed so things 'fit'. I will leave the specifications to the imagination.

The "F" in F scale [1:20.32]stands for the "Fifteen" in 15mm/ft [the actual unit conversion. The use of Fn3 to denote track gauge relative to scale is the same as IIm indicating Scale II [1:22.5/1:22.6] on metre gauge track.
Obviously Fn3 is 45mm track [3x15] and is an indicator of how it was selected; standard gauge F is 70.6 mm [1435mm/20.32]

Dr Rivet.
Gee, 'F' is for Fifteen then. It all makes sense! A 'Fine' scale it is indeed. One of my Favorites!
I kept the list of scales in regard to 45mm gauge track otherwise it all gets way too much to explain.

Thanks Andrew for the education. It takes time to consume the information but sure I will.

Someone new to all this will still wonder where 1:29 fits in and why early Bachmann 3ft gauge models are in 1:22.5 and other brands are in 1:24.
Japanese standard gauge models are in 1:30 scale.
Australian and German 750mm gauge models are in 1:19/1:20.3 scale.

'Large scale' has it's quirks.

I saw a real steam train on ebay and it is the Aster 0-4-0 and it is a gauge one scale. I wonder what is the difference between g scale and gauge one. Can it run on a 45 mm rail?




back to the original question. the best known "Gauge one" or "Spur I" in german, was Maerklins "Maxi" line of products.
they, and smaller comanies, that jumped the bandwagon, did use other rails!
yes, they were/are 45 mm from inside to inside, the same as the largescale track introduced by LGB. but the railheads are narrower and not as high, as in largescale.

so you might have difficulties at combining gauge one stuff with largescale stuff. one, i remember having read, was gauge one wheels falling into the largescale frogs now and then..

Scot's illustration is the best example I know of that explains our various scales. I printed out a copy years ago and have it with me at train shows to help answer the question, "WHAT SCALE IS THAT TRAIN?". As the old saying goes, "one picture is worth a thousand words".


Thanks, Scot.

Thanks everyone! im glad the chart has been useful..
I just did a few minor tweaks..I added "Gauge One" and moved down the text to 1/29 and 1/24 scales, to help show they dont have a "name" other than 1/29 and 1/24!
And I modified the wording in the "Model Locomotives" title to include the phrase "Large Scale"..which wasn't there before.
Here is the new version:

Scot,

Thanks for posting this. I have used your chart over many years to explain the various scales to friends. This picture "definitely worth a thousand words"!

Thats an interesting idea, but, these are real locomotives, I seriously doubt that there is a prototype that is similar across all real track gauges. Scot used reasonable images. Scaling down a standard gauge loco wouldn't accurately illustrate the width of the engine to the gauge of the track. The two footers stick out a lot more. Chuck
