I'm not sure, but there are actually two standards which have to co-relate
here - the loading gauge, which is the maximum volumetric space in which
rollingstock is permitted to occupy, and the structure gauge, which is the
same but keeps structures a pre-defined distance *back* from the maximum
limits of the complementary loading guage profile.

Craig.
