1980s Flying Scot Set HO or OO

[hioo01]

I have a few sets my dad purchased in the 1980s in the US, the Flying Scot, The Orient Express and The Battle of Britain sets, all look to have similar passenger cars and loco (a 4-6-0) and I was hoping to purchase a DCC locomotive that would work well with these coaches. So my question is, are these trains actually HO like it says on the box, or are they OO that were just marketed as HO in the US? I've scoured the internet and I'm leaning toward them actually being OO but I figured I'd ask the experts!

Dear Hi,
I believe you are correct; they are OO.
They are great sets! Enjoy them!

Even being 00, they do run on a true HO track, right? That's important so that the OP can find the locomotive. He's looking for to pull his cars.

Yes, they will, and Bachmann UK will have an appropriate locomotive.
Have fun!

I found this string quite interesting.  Enough so that I found this.

It appears that only similarity of the two is the track gauge.  The distance between the rails.

HO "SCALE" is 1/87
OO "SCALE" is 1/76.2

So, OO "SCALE" (using HO  scale track) would actually be a 'narrow gauge'.

16.5mm track used for OO gauge comes out to 4ft 1.5in, rather than 4ft 8.5in standard guage. Making it a narrower gauge, but not any recognizable narrow gauge.

Just what I needed to know, thank you! I've been running them for years on regular HO track, I just upgraded to DCC and would like to still get some use out of them!
