As I've said earlier, I've visited the construction-site.
My first impression: very nicely themed.
I really like the entrance to the queue, where you walk through a mine shaft.
I also really like the other theme-objects in the area and queue, like the little train in the queue.
Also really nice: The exit of the coasters is in the middle of the station, between both tracks. You'll walk between and very close to both tracks and end up at the food stal/possible photo booth or souvenir shop.
What they told about the coaster(s):
Height: 20m
Length: 218m
Top speed: 60 km/h
Total ride time: 01:05 (mm:ss)
Minimum and maximum rider size: 95 cm - 205 cm
Trains use soft wheels to reduce noise.
The position of the lift and both spikes on one side and the low to the ground turns on the other side have been deliberately chosen to keep most of the noise away from the animals.
Both tracks will be connected to a (to be announced at ride opening) charity. Depending on the winner of the race, Wildlands will donate an X amount of money to the corresponding charity.
According to the park, the operators don't have any influence on the outcome of the race. Both trains will be released from the top simultaneously, gravity and friction will determine the outcome of the race.
Tweestryd will open at the end of march.
Here are the pictures, a video of the tests will follow later this week.
