HO and OO Scale Locomotives – Why Do So Many Railway Guys Love Them?
In countries filled with hobby lovers such as Australia, Great Britain, Canada the U.S., and Japan, HO model railways are the number one guy!
This scale has captured the hearts and imaginations of millions around the world.
HO and the United Kingdoms OO scales are probably special to so many due to their user friendly size which allows model railway builders to pay extra special attention to detail.
With these two scales visibility, one can spot the tiniest flaw in detail… so those endeavoring to build life like scenes and replicas are devoted to giving their admirers nothing short of perfection!
Not many train guys are aware of this although the H in HO stands for Half of 0 scale. O scale is a scale introduced by Germany toy manufacture Marklin around 1900.
O scale had its run of popularity up until the 60′s when model train collecting became more of a ”BIG BOY HOBBY”, rather than a game for tots! In the U.K. they have a similar scale known as OO which is 1:76 scale or OO Gauge
HO & OO Gauge Numerically Breaks Down Into This Ratio –
- HO is 1:87 of Full Size
- OO is 1:76 of the “Real Deal”
This Translates HO Scale as (1) inch on the miniature… representing (87) inches or 7¼ Feet of “Real Train!”
and
OO Gauge tips the scales at (1) inch equaling … (76) inches or 6.3333333 Feet. “WOW” that was a mouth full, I hope we didn’t loose you…? #&%!
- HO Scale (Track) Gauge = 16.5mm (distance between “running” track)
- OO Scale (Track) Gauge = 16.5mm

Hello:
Nice web site with some helpful data for sure.
Was wondering what your thoughts are on the use of 1/144 scale
kits with 1/160 or N scale as in compatibilty?
Is it the same as modelers using 1/72 and 1/76 together.
Meaning…”they are not the same scale”…atittude.
I just wish that there was a line of 1/144 railroad models
out there that were powered so a person could get into
model railroad in a serious way. Or maybe there is.
Again, nice web site. RWMDRON
