I don't believe so. *Sorry, miss remembered. See extract at the bottom, sorry for misleading.
I believe W10 and W12 gauges are based upon W9 but with differing 'additions' to cater for different sized traffic.
I did have a handy guide to Gauge profiles, I'll try and relocate it.
If I am incorrect, no doubt someone is able to correct my error.
EDIT:-
Gauge nesting - W6a sits within W7, and W7 sits within W8. That's where it stops – part of W8 protrudes outside of W9. Nesting refers to a numerically larger gauge being progressively larger than the one with the previous number in the series. However, the concept of nesting falls down when the network cannot accommodate ever increasing size, or different rules are applied. W10 gauge is taller than W9 gauge, but W9 is wider, for example.
So in theory, a route can be tall enough to accommodate W10 traffic, but not wide enough to accommodate W9.
