English Model railroad question

[whecsailor]

Hi

I am seeing kits that are either 7mm or 10mm

http://www.modelrailways.tv/standard_gauge/wagons.htm

are the HO (OO ) scale or something else?

thanks all

I'm actually wondering what gauge they are myself, 7MM is 760MM gauge in HO here in Germany, but standard gauge is 16.5MM. Maybe they just don't know what scale it is

In the UK we use OO gauge (similar to HO ) which is 4 mm to the foot.7 mm to the foot is O Gauge and is where you guys get HO from ( HO = Half O) .I think 10 mm to the foot is Gauge 1.

OO and HO are compatible, but you have to be careful on turnouts.

Lewisner is correct, 10mm scale is Gauge 1, 7mm is Gauge 0 and 4mm is Gauge 00 (as opposed to 3.5mm which is H0 and is what the rest of the world uses). Both 00 and H0 run on 16.5mm gauge track. The difference is historical and dates back to the 1930s. Since the British loading gauge, as the oldest, is smaller than other countries there was difficulty in fitting the early electic motors into British models, so the manufacturers scaled thing up a bit. As is often the case there is now too much 00 equipment to do a change so we have this anomaly of under gauge track. Perfectionists either model in 3.5mm or more usually use a more scale gauge such as Protofour.

A similar situation applies in the smaller scales.

British N Gauge is to 1:148 scale and runs on 9mm gauge track while the purists in the 2mm society use the same scale but hand build track at the correct 9.7mm gauge.

In the rest of the world I think that the modelling scale is 1:160 but the track is the same.

Follow this for the N Gauge Society’s home page and more detailed information.
