Why is called HO?

The first Russian railway was laid at 5'0" gauge. Somewhere along the way they must have got bored with counting off those additional four millimeters! Did the yank modellers of Russian railways reduce their track gauge by the requisite 1/12mm?

Now you see why the designation refers to gauge first and scale second - either "n-scale" is or "n scale" isn't!

British N scale is 1:148.

P160 finescale uses 8.97mm gauge.

HO is only 3.5mm : 1 foot in Britain only - the rest of the world uses slightly more sane scale ratios because we all gave up archaic measuring systems based on barleycorns decades ago.

Good point - I was going for a logical figure ;-)

Is that a typing error? 1 foots worth of millimeters divided by 2mm equals 152.4, not 152.1?

Who uses that?

Regards, Greg.P.

Sort of correct. Iberian gauge is officially 1668mm (about 5'5.6") but was originally 5 Portuguese feet (1664mm). At one stage Spain used 6 Castilian feet (1672mm).

Iberian gauge is also used in Argentina and Chile.

They just say 1:152.

All the the P160 literature I've seen is in German so draw your own conclusions. :)

Ahh, like the yanks with HO - they start with a non-rational set of factors, round them to make them both less accurate and different to everyone elses and then claim them to be the ultimate!

Tough call - perhaps the Lichtensteineans(?)

Are you sure Greg?????

Can you think of anywhere else generally using 3.5mm:1foot, other than a few odd people outside the UK (add in the IOW and Channel Islands pop and prototypes) who model British prototypes?

(the US is a wrong answer) =8^)

That's all well and good, except it is wrong.

The "O" (oh) is not right. It is supposed to be "0" (zero). So, it is H0 (half-zero) rather than HO (half-oh).

I think that we are allowed to split hairs in this thread. :-) Peteski

And thus the rivet counters become digit counters. Why am I not surprised?

Just can't measure 9.00mm I guess.

I thought N meant "Non Scale" :)

That's wrong.

In Denmark we went metric by law as late as 1904, this means that feet and inches was still in everyday use when I was an apprentice in the

Wrong again.

In Denmark, Sweden, Norway, most of Germany, Switzerland, most of Austri, Italy, and Eastern Europe 1:45 is used. 1:43.5 is used in France and by a few in Germany.

So what have you got against rivet counters - why this need to dumb down the hobby and the world? I don't insist you count rivets so you have no rational need to demand that I don't!

No, it's 0.03mm gauge widening in curves.

That's _102_ years ago - the number of people in Denmark old enough to remember pre-metric days would be almost down to single figures.

Did you make many parts in mixed Imperial/Metric measurements?

Lima produced in (ahem) 1:45 (cough) scale in the 1970s which lead to a small revival of European 0 Scale but 1:43.5 is/was more commonly used by established enthusiasts in France and Germany.
