The difference seems mainly to be in scope and purpose.

The wiki entry for railway=narrow_guage says "For small railways in
parks which are tourist attractions and they are not part of a railway
network, consider the usage of railway=miniature."

I think that railway=miniature is mainly for railways that aren't part
of the transportation industry and are more likely tourist attractions.
