I was interested to see
It's been about 10 years since I was on it, so I've been trying to remember the track layout all morning. As far as I can remember, you do start off on one platform and finish on the other and the tracks don't cross. However, I think I'm going to have to find a good photo, so I can envisage the layout and try to untangle it into the basic ring with a twist to convince myself it actually is one.
