G 1:22.5 Scale Standard Gauge

Also known as Gauge 3.

1:22.5 Scale on 64mm track.

There was a layout at Llangollen in this scale....

sorry to be the party-pooper, but traditionally that would be gauge 2 standard, or gauge 3 metre (1:16).
the modern "gauge 3" misnomer was/should be 1:22.6 at 63.5mm.

I wish I had the space, time and modelmaking ability to add a little section of Iberian gauge line with 74.1mm track, to run my Piko railbus ('ferrobus') more correctly - now that would be an interesting chassis build to accommodate such long axles. I've only ever seen the occasional static loco model, built to our scale but with 74mm track, in Spanish museums. I only mention it because it would need you to add another line to your table - Gauge IIi! :rofl:
 
If 1.22.5 models of standard gauge prototypes, running on 64 mm/G3 track, are your thing then GRS's Homepage is the place to go. Also The Gauge '3' Society, British Standard Gauge, Large Scale Garden Railways for its umbrella organisation. However, I doubt you'd be too wellcome if you referred to them as "G Scale".

Just as much as if you were to use that term for 10 mm/1:32 scale models of standard gauge prototypes. These are run on 45 mm gauged track are termed G1 not "G Scale". Old standardisation terms that date back to the dim dark past of the hobby. Like O Gauge/32 mm, etc'.

"G Scale" is not a scale. It's a misnomer. Sure, you could use "G Gauge" if you were trying to say something is compatible with 45 mm gauged code 332 track systems, like LGB's, but really it should have no other application. Max
 
Sorry, I had a moment of mischievous boredom last.
Most people who know me would have told me to shut up and ........, well just behave.

But it does go to reinforce the point that G Scale is not a scale and is wrongly referenced.
My models are 1:22.5 scale, or their abouts, all except for one just now are narrow gauge, so talking about them here is acceptable, i have one model which although it's the same scale because it's based on a standard gauge prototype I told this isn't the place to discuss it, so should I feel put out that only my narrow gauge trams should be mentioned here.

Then we have a live steam loco, and coaches yet to be finished which are 7/8" scale running on 45mm gauge track which seem to me acceptable, which goes to demonstrate that its not just 1:22.5 scale narrow gauge that is acceptable to discuss here but anything which runs on 45mm gauge track.

Yes I am being awkward and other things in the readers mind, but I'm right, oh, and I am letting myself be distracted from household chores, so don't take this thread too serious, but I am right, and I do find it extremely frustrating that a modelling size referred to as a scale has absolutely he haw to do with scale.

Another question on the topic which is relevant though.
I am and will be running bachman trams which I believe are intended to represent 1:22.5 scale, Manx Electric Railway trams which are a 3ft prototype and I have scaled for operation on 45mm gauge track, and some Hong Kong trams in the list to build (if I survive this thread) which are a 3ft 6in prototype and will be built to scale to run on 45mm gauge track. Ignoring the Groudle Glen stock which doesn't utilise overhead wires.
Taking the prototypes difference of scale in to consideration, what overhead wire height should I adopt for the garden line and indoor layout, thoughts?

Another wee thing, when the indoor layout is finished it is planned to take it to exhibitions, what scale should I say the layout is?

Okay sorry, I was rounding up, the third rail on my test track is 63.5mm gauge, I'll shall try and remember to be more accurate when typing in future, he says bowing.

Ignore the gauge of the track, and reference the scale of the models to the prototype:
1:22.5 if metre gauge European.
1:13.7 if 7/8ths representing two-foot (-ish) gauge.

Anything else, you can do the maths! :D :nerd:

Yeah, it should be viewed a conglomeration of scales - some slightly more accurate than others, but only if that sort of things worries you.

Which, I suppose, is why the description 'G Scale' continues - 'cos we all get on with our own thing under the umbrella term :nerd::nerd::nerd:

Yep. I always tell (non model railway) folks who ask, that I have a G or Garden Scale railway, which seems to satisfy. If pushed further I say I model British narrow gauge railways, based on a prototype running on 3 ft gauge track. If there are further questions (and they need to know a bit of which they ask) then 16mm/ft or 15mm/ft scale running on 45mm gauge track, so ‘about’ 1/20th scale. That seems to do the trick.

Within one of the links I posted is this little explanation of the history of the gauge#/scale standards adopted here Early Days of Gauge 3 | Gauge 3 I wouldn't get to hung up about the odd 0.5 mm on track gauge as even the major proponent of products for this standard don't seem to GRS 64mm | Garden Railway Specialists Tel:01844 345158 :)

Now, accepted ratio for 3' on 45 mm gauge is 15 mm scale, or 1:20.3 if you wish. This is the standard IoM modellers use, there is group who exhibit at the 16 mm NGM show each year. I model a lot of US outline D&RGW and logging NG locos and kit, 3 ft gauge. This to the US market is F scale, and as it models narrow gauge (n) running on 3ft it is commonly referred to as Fn3.

3'6" Gauge is sometimes referred to as "Cape Gauge", as it is used a lot in South Africa, and other nations that were part of the old British Empire. Used on tramways too ! There are a few on here who model 3'6" Cape Gauge on 45 mm track, likewise a few who do trams on that too, mostly our Australian friends here. There really is quite a broad church on here. Don't be afraid to raise and discuss anything. There are some G3 people here, and because of the crossover of their chosen scale (ok, near scale if we are splitting hairs) to Erupean narrow gauge modellers venture over there too. It follows 7/8ths on 45 mm gauge aproximates to 2ft gauge prototypes.

Really if you are going to shows just declare the scale of model you are choosing to run. I'm sure event organisers will put you straight on what they want/accept. Be creative. Keep a stock of props that can be placed on your layout to match the scale you are running. Then have fun switching them during the show. Most buildings you see on freelance large scale exhibition layouts are underscale anyway compared to the stock they are running. When you get to garden scales like16 mm structures can get quite large and unweildy - see the marvellous Brunel products if you want to get an idea.

Really, just do what you want to do and enjoy yourself. Max.

P.S. So how did 1:16 get to be such a commonly used scale for tram models ? It was also the scale used by makers of "ships of the line" when presenting models to the Admiralty as proof of finished product specs. Take a trip down to their museum at Greenwich some time.
 
To my thinking, your MER stock will be 1:20.3, running on 45mm gauge track; and, on the same track, Groudle stock will be 7/8ths or 1:13.7. But I suspect you know this already...:D

Running 1:13.7 stock on a 1:20 scale garden line didn't sit well with me. I could more or less overlook the spacing of the sleepers, but everything else jarred; it was a bit like running OO9 on an N gauge layout. So my Groudle Glen stock doesn't come out much; but I firmly believe in Rule 8: it's your railway, so do what you like!
 
Sometimes it’s just loading gauge? For instance in the 12” to the foot world a train running on HS1 isn’t a different scale to a train running on network rail; it’s just bigger. So pretty much anything can be justified on 45mm track……maybe.

I nearly did!

But the discussion of scale, gauge and kinetic envelopes is always an interesting thread, done to death but always a few new perspectives each time we explore this very complex area. To my mind scale is confused with label, for instance many at model railway shows will say they model in 00 scale, but at what gauge 16.5, 18mm or some other larger gap between the rails?. The same gauge that HO Modeller's at 3.5mm to the foot use ie 16.5 mm track gauge. Gets even more complex in our size with out track at 45mm being used for standard gauge, sundry narrow gauges including 2ft and smaller. Time for me to shut up!

The author of my local 16 mm group posts has pinned a remark in their quarterly "Bulletin" that mentions, not by name, the issues caused by my liking of US subjects, which are modelled in 15 mm scale. That being their going outside of most of the group's lines loading gauges (never mind some are 32 mm gauge and not 45 mm, I do 16 mm too) , which are built around generally more compact 16 mm scaled prototypes. Some might think it ronic given they are a larger scale at 16 mm they require a smaller loading gauge. Assume nothing. I'm not bitter, really :D Max
 
And Korm's table seems to miss out on the "Irish" gauge of 5'3" (1600mm)?

Still extensively used in South Australia & Victoria - particularly on very large suburban networks!

Work out the true "scale" if modelling for 45mm gauge track............. ;)
