Not sure whether anybody has noticed this, but this is not standard Eurofighter tri-track. It
is a lot 'chunkier.' The gauge (width between the rails) appears the same - 1.2m, but the diagonal stanchions between the centre rail and the main rails are much thicker. Also the lateral diagonal bracing goes straight to the rail, as opposed to the rail tie-bar. Here are a couple of images that hopefully demonstrate this:
This is standard tri-track:
Notice in particular the bracing from the centre rail:
Now this is SW7's tri-track:
Now the bracing from the centre rail:
This is obviously because SW7 uses heavier trains, and as such I would not be surprised if we see very little ladder track used, even on the indoor sections (as is normally the case with Eurofighters). It is interesting how they have opted to use strengthened tri-track, as opposed to the box-track used on Takabisha.
The grey-ended supports (as in the last picture) are very odd, as there are no bolt holes at the end. It could be, as some have suggested, that these supports will be embedded in concrete. It could also be that they will fit inside a 'sleeve' for adjustment on site (as stated before, Gerstlauer don't build many terrain coasters, so this could give them a little flexibility in some areas).
