Just to put the rumours to bed, I've seen a copy of the plans and they match the ECC drawing.
There are a few extra bits and bobs to mention;
* The station building has two levels (ground floor and first floor), but part of the ride passes below the station at what would be basement level.
* The ride will have a capacity exactly the same as Corkscrew (1200pph).
* In terms of scale, the lift hill, station and final helix take up the area previously used by Corkscrew, all of the remaining ride area is on newly freed up land through woodland etc. The lift hill is about 2m shorter than Corkscrew's, but the overall level differences are about 5-7m greater than Corkscrew due to the valley sloping away and the underground/trenched section.
* The track will be painted brown.
* The theme seems to be haunted type (dark forest perhaps?) as the entrance gates to the queue line are similarly themed to aspects of Haunted Hollow.
I'll also try to describe how the ride layout goes:
The train exits the station at approximately ground level, ascends the lift hill, then descends the main drop. It enters the helix before going into an airtime hill, and then passes out into the woodland with a series of overbanked turns and airtime hills.
The train then returns to the station at first floor level, something happens within the station whereby the coaster enters forwards at the high first floor level but exits backwards from a tunnel at underground/basement level (approx 10 – 15m level difference), then passes through a 3m deep trench in a helix which rises back up to ground level. It then enters a switchback in order to pass into the station forwards again.
I also believe that the ECC layout is incorrect within the building, and that something much more interesting happens in there...
