I'm not sure about "summer_toboggan"... see this: https://wiki.openstreetmap.org/wiki/Tag:attraction%3Dsummer_toboggan

and this: https://wiki.openstreetmap.org/wiki/Tag:attraction%3Dalpine_coaster

I think "alpine_coaster" would be more appropriate here.
As for the track, I think it should be fine as it pretty much matches the GURS satellite image...
