Art Howes posted:Hello, on the first Service Snack the characters after the dash looked like number zero (0) to me and not the letter O as Dean identified them. Unfortunately, this confusion is very common, such as, are we using O gauge or 0 gauge trains?
English-speakers often - not always - tend to pronounce both the number "0" and the letter "O" as "oh"; can't speak for other languages. So, naturally, "zero" scale/gauge became "oh" scale/gauge as a speech habit.
"H0" scale/gauge indicates "half 0" gauge. This refers to the gauge, not the scale (that 0/H0 relationship is another story, especially in N. America).
I notice that articles from the TCA will often print "HO" as "H0", which is actually correct - it's "half zero" gauge, properly, not "half oh". And we do "zero scale", not "oh scale", but try to change that....
