Isn't it the case that the loading gauge is the maximum size of train
allowed to fit with the structure gauge.

No.

There is a gap between the the loading gauge and the structure gauge -
the ''clearance'' I think the correct term is.


Nick, do you ever read all of a post before commenting?

"A train has to fit the defined loading gauge for the route and this
means it will
automatically within the structure gauge (plus clearance)"

The loading gauge for a route is the minium space available once the
structure gauge and the clearance have been taken into account. In
most locations, the structure gauge will be actually be greater than
the loading gauge, but when looking at the route as the whole, the
loading gauge is the important describer as it takes into account
tight spots and relevant speed restrictions.
