Definitely got to have a drive round having driven all the way down there Scotty... It's well worth it.
You just need to keep an eye on your mirrors... If you have a passenger to help keep a look out as well it's even better
My car was pretty low but I didn't have any issues with the train (I did book and get on as a high vehicle on the single deck) or the track!
The only other thing I would say is 'E's idea of a slow lap and yours might be a bit different!!!
