Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Your comment on gauge makes it sound like kinematic and dynamic aren't synonyms. I had to check.

Er, yes, I meant static. But here is a fuller classification of gauge types (though I'm not sure I got the English terminology right in each case), generally from narrowest to widest:

Construction gauge/vehicle limit profile/loading gauge at standstill:
this is the actual limit for the cross section of a specific railway vehicle.
'Static' loading gauge:
a railway vehicle must fit into this even considering the worst combinations of curves and the lateral play of moving parts (wheel in rail, axle in axlebox, suspensions). Until recently, the construction gauge was caluclated from this.
Kinematic (dynamic) gauge/reference profile:
similar to the previous, but dynamic effects like tilt in curves and uneven track are also considered. It's also called reference profile because both construction gauges (for vehicles) and structure gauges (for track) can be derived from it.
Structure limit gauge:
derived from the reference profile by considering the tolerances of track-laying.
Inner structure gauge:
the standard of a railway company for the space within which nothing fixed can protrude.
Outer structure gauge:
the standard of a railway company for what extra spaces to keep clear (for aerodynamics, for track workers, for waiting passengers etc.) in various situations: tunnels, bridges, overpasses, stations, side-by-side tracks etc.
the entire room demanded by a railway line, including ballest bed and catenary

BTW, for A swedish kind of death, here is a drawing from my work (clickable thumbnail):

It displays the rough outline of a Swedish IC car to be measured (no precise data was available then), the Hungarian and Swedish (Scandinavian "A") static loading gauges, and the narrowest (old standard, non-electrified line) and widest ('new' East Bloc standard, electrified line) structural gauges of potential test tracks in Hungary. It can be seen that corner height could be expected to be a problem on old lines, would it not be the case that the car apparently doesn't utilise the Scandinavian loading gauge in full.
