Longest coaster in terms of time is:
Euro-Mir in Europa Park, Germany - 273 secs (4:33) *snore*
Seriously, if this coaster is longer than that the put through will be appalling.
Actually that's not true, as The Ultimate lasts just under 7 minutes, station to station. There might be a longer one in the world somewhere (though the only operating coaster longer than The Ultimate only has one lifthill that presumably isn't paunfully slow).
30 workmen on site is massive amount compared to what we've seen before. I think construction will get faster at an exponential rate from now on.
