Nah bugger it, you've caused me to procrastinate, so here's my idea. I didn't want to procrastinate for too long, so the drawings aint the prettiest.
Eureka Mountain 2: The Forbidden Shaft.
As the slogan goes "Toyota Yaris combines Toyotas big ideas into one small car". Well EM2:tFS combines Intamins big ideas into one (relativley) small coaster.....Mix Fahrenheit, Maverick, Piraten/Kawasemi and Th13teen and you've got some idea of where I'm going with this.
I've also "negotiated the brief" a little bit , and used up the sites of the old Chairlift station and the currently unused Thunder River water lagoon (so to construct this ride, Goldrush would be closed for a few months, all water removed, and footings placed into the base of the lagoon) But the ride is still entirely within goldrush, so it's all legit IMO
So here's an overview of how the front facade would look. Typical mine theming, with a new rocky facade and a bunch of mine buildings. You go in under a "Poppert head" and along some shed like buildings. Overhead there would be moving machinery like pulley wheels etc
The main bit of the queue is in the show building, in an indoor cavern where mining is taking place. Stalagmites would protrude from the floor, and floor space would also be taken up by bits of mining paraphenalia. The queue therefore would wind its way randomly around everything. The roof would feature stalactites and small rocky bits covered with gold leaf (to give the impression of gold deposits) as well as hanging lanterns and rope pullies with hanging buckets of spoil. An interesting feature would be a section of track (between the final block brakes and the unload station) that would come out into this cavern overhead. So every now and then guests would see a trainload of recovering riders passing overhead.
The queue would head upstairs and into the station. These spaces would be a bit more formalised, with squared off walls, with buttresses and timber cross planks.
The trains would be the 3 car, 12 rider type, but a bit more blocky looking, with a timber texture and metal bracing to look like mine carts.
So here is the layout:
From the station you go down a small drop, straight into a surprise barrel roll, which is hidden by the darkness of the mine tunnel you are in. Immediately you round a U turn and hit a block brake. The lift then takes you up 90 degrees to a height of 30m. The lift would be fully enclosed by the tall building seen in the first illustration. At the top you go over the edge and down a "steeper than vertial" drop and exit the building at high speed (imagine the visual impact to bystanders of watching trains being spat out at high speed!)
From there its straight into an immelmann, but on the pullout you whip around a helix. From there its straight into a corkscrew that goes over the gold rush footbridge. The track continues around an overbanked turn that goes slightly over the Big Brother Cafe (or whatever its called now)
The pullout would be quite steep and this leads you into the next trick of the ride....
The track dives into a 'cut and cover' tunnel themed to look like a mine tunnel entrance, and this would contain an LSM booster launch. But here's the fun part. The tunnel would be pitch black when the train first goes in, yet filled with smoke . At the right moment a large explosion sound effect would be heard, and the entire tunnel would be illuminated from behind the position of the train with red and orange, in a sort of fake fire effect (Like on Valhalla at BPB) In addition the train would pass under a set of heated air curtains (like at the entrances to some buildings/shopping centers) which further enhances the explosion effect.
From the launch its straight up into a cobra roll, and then the fun bit, a bunch of airtime hills ( )
At the end of this section you curve upwards and renter the show building and back into a 'mine tunnel'. In the darkness is a surprise bunny hop. You are then brought to a stop and reach a dead end . You hear the sound of the ground crumbling, and then just like Th13teen the track drops. The track would drop into a smoky area (to simulate the dust that would get thrown up as a result of a rock fall) and at this point the ride is over, and friction wheels advance you back to the station, passing through the aforementioned cavern space on the way.
Here is a quick 3d sketch of how the ride layout looks, but without the show building.
And that's it.
