unusual scales

[Anonymous]

one day I was making a search at the walthers website and when I chose the scale I noticed some scale I've never heard of. those were I, TT and V, does anyone knows anything about them? I've seen this other scale,"oo", mentioned in some model railroader issues. does anyone operate trains in such scales?

I dont operate in ethier of the scales but I believe TT is equal to HO and I is equal to O and V is equal to V. Correct me if im wrong.
i hope this helps

As far as I know TT scale is between N and HO it is 1:120 scale , V scale is 1:440 scale which is normally used in ship modeling, oo is the British version of HO scale and is 1:76 scale, if if your other letter is an L Large scale, then F scale is 1:20.3 and G scale is 1:22.5
Hope this helos

If your first scale listed is #1, it is 32:1, and was popular in the early days as a tinplate size, by Lionel, Ives and a few others.It was known as "Standard" gauge. There have been actual scale models in #1, and most recently, still made by Marklin.
TT was reasonably popular in the 50's, before N scale,( and it's predecessor OOO,)took off in popularity.
OO as used in Great Britain is not really a true scale, it is OO ( 4mm )models running on HO track, (3.5mm ).
True OO existed mainly in the USA in the 30's and 40's, and was overtaken after WWll by HO.
Never heard of V, but one of your other respondents answered this.

Actually, 'TT' is about halfway (size-wise) between 'HO' and 'N'. I own a German prototype 0-8-0 tank engine in 'TT' scale. 'OO', however is the British equivalent of 'HO'. It is just a tad larger than 'HO', because when they first made models in this size, the technology in that time (I think the 1930's?) was such that a motor that could fit inside a train of that size was as small as they could build. Even so, 'OO' trains will operate on HO guage tracks, and (I think) will not look out of scale. I own a British prototype OO scale 0-6-0 steamer, and it looks okay on my HO layout.
As for 'V' scale, I haven't a clue! 'I' scale, though, I think is about the same size as 'G' or #1 guage, usually used with garden railroad layouts.
I hope this info helps you!

OO is 4mm to 1ft or 1:76. In Britain it is the widely used scale, but most of the commercial trains run on HO track. There are 2 movements to use more exact track gauge, 18.2mm and 18.83mm. There are problems with wider gauges because a lot of British locomotives have prominent bits placed outside the wheels and the extra wide wheels make for clearance problems.
In the USA, OO was modelled on 19mm track. Lionel made OO trains in the late 1930s. See the latest issue of Classic Toy Trains.

TT scale is/was 1:120 proportion. It dates back I think to the 1940s -- stands for "Table Top." Kemtron used to make some TT items.
OO was popular in the 1930s when people wanted a smaller scale but the motors at the time had a hard time fitting in HO scale engines. Lionel had an OO line for a while. Even now some British models are marked "OO/HO" meaning the gauge is HO but the scale is 1:76. Model Railroader used to print letters from an old timer named Temple Nieter who would sing the praises of OO long after there were no commercial models being sold. I remember photos of a magnificent OO layout, a Norfolk & Western with all scratchbuilt steam locos and scenery that would hold up even to today's standards -- I recall a shot of a long freight along a river bank that was as realistic as model photos come. I think the builder was Carl Appel (spelling?). I wonder what happened to that layout and the equipment -- think of having a beautiful layout and trains that nobody wants!

hello,
for the tt,yes it's 1/120 scale and mostly use by eastern europe modelers
for I,it's the old european way to say #1 scale or 1/32.
for the V,it's also called as scale 5,mostly for gaden purpose,the kind of locomotive that actualy pulls you on your garden railroad.it's quite huge and work as the real one.
you've got also the 1/20 for live steam engine with remote control in france.
LGB was also called IIm for scale 2,metric system
at it's begining.
hope i help dissipate the mist

The major scale here in the UK is still OO/HO for British prototypes that is : 4mm/1ft 1:76 scale models running on HO 16.5mm guage track. OO/HO equipment will therefore run fine on any HO layout but will be a bit overscale in comparison to HO equipment. This is a throwback to the 1930's when the small motors available were still just too large to fit into the smaller British locos. Finescale 4mm/ft modellers in the UK use either 18mm guage track (EM scale) or 18.83mm (Protofour / Scalefour). There is no real market for HO British outline models in the UK the major manufacturers are too committed to OO/HO. British HO modellers tend to model American (like me) or European prototypes.

TT is 1:120 scale or 3mm/1ft running on 12mm guage track. There are a few die-hard British modellers who scratch- and kit-build models in this scale but the majority of models available are northern European, particularly German. I don't recall having ever seen any American prototypes in TT but I may well be wrong.

If you're after unusual scales then check out some of the British narrow guage scales:

009 - (1:76 scale 4mm/1ft on 9mm track) representing 2ft to 2ft6in railways,

OOn3 - (1:76 scale on 12mm guage track representing 3ft guage prototypes),

HOm (1:87 scale on 12mm guage track giving meter guage prototypes)

and finally the weirdest of the lot "5.5mm scale" - (its never been called anything else) 1:55 scale 5.5mm/1ft using 12mm or 16.5mm track for 2ft or 3ft guage respectively.
