Unlikely. China's narrow gauge is mostly 30" (or is it 750 or 760mm?), not metre.I wonder if maybe those steamers came from China?
Having diesels in the 60s doesn't mean they didn't also have steam. I learned recently that there is no more "real" steam in Vietnam, but there was until about 2002.They were running deisel in Vietnam when I was there in the mid 60's.
is there a way to make our new steamer run black smoke like they did back then.
