ALL plans I have seen have no mention of any tunnels. The queueline is clearly marked on the plans and uses the old Dynamo/Nemesis queueline. There is nothing about tunnels and creating more tunnel systems around Nemesis would surely make the ground unsafe for the ride above. Plus Im almost certain they would never get planning permission to create tunnels that stretch that far.
Ok heres the queueline plan has detailed on the application form:
From what I can make out, the queue will follow the existing queueline almost identically, all the white coloured areas are the existing floor, light brown being new raised flooring to avoid damage to the large trees either side and dark brown being new block paving.
I can only guess the actual queueline layout, but Im sure my guess is fairly spot on. Red being the normal queue, blue being the single rider queue and orange being fastrack.
