Venezuela also had some 42" gauge.
It should be noted that Brazil is meter and 63" - I don't know of any standard gauge.
Japan was 42" gauge, but I think much of it is being converted to standard.
Philippines is all 42" gauge, the sugar lines used a variety of narrow gauges.
Costa Rica is now all 42" gauge.
All the Panama banana lines were 36" gauge, except the border area with Costa Rica had both gauges (including some dual gauge) at various times. The Panama Railroad paralleling the canal was built as 60" but has since been changes to standard. There were narrow gauge construction trains for the canal itself. Not sure what gauge the Canal Mules are.
Hawaii seems to have been mostly 36" gauge, but I think one railroad was standard, and numerous narrow gauge plantation lines.
Honduras - all 42"?
Columbia had some isolated mining standard gauge.
Mexico had standard and 36", but I believe there was some substantial 30" mining.
Cuba, other Caribbean islands and adjacent South American coast nations used a variety of gauges from standard, 42", 36" and 30" for common carrier, mining and plantation lines.
South Africa at one time had a substantial 24" gauge common carrier. I think what is left is primarily operated as a tourist line and I know some of the GE diesels have been resold to 42".
Australia still has quit a bit of 42" in addition to standard - wasn't there some broad gauge also? Plus a variety of narrow gauge plantation lines.
New Zealand - all 42"?
The basic pattern for narrow gauges was this - If the line was originally built under American influence then it was typically 36" gauge, if English then 42" gauge, and I'm guessing other Europeans are responsible for the meter gauge influence. Smaller than 36" was usually limited to certain applications typically a mining or plantation, but there are obvious exceptions.
Some companies such as United Fruit (Chiquita) who had standard gauge, and both 36" and 42" narrow gauge common carrier and plantation lines I know to have moved many of their diesels between 36" and 42" properties and had at least some of them built to be easily converted.
