There's the Toronto gauge, the Japanese high speed rail gauge (which is standard, 1435mm, for the world but wider than what was used before in Japan, 1000mm and less) and the Spanish high speed rail gauge (which is also standard, 1435mm, even though they usually use Iberian gauge which is wider - and on this, they have some interesting train designs that are capable of automatically switching between the two).
