I believe this project has been known about since last year, but with vertical construction now well underway I thought it would also be worth a mention here!
Junker is due to open at Powerpark in Finland later this year, and is a launched Infinity Coaster (with Karacho style trains) being manufactured by Gerstlauer. The launch will see riders reach a speed of 62 mph in 1.9 seconds, before going through a top hat, dive loop, vertical loop, another dive loop and corkscrew, as well as some other twistiness. I think that the majority of the layout will be above a body of water, although this has obviously been drained at the moment to allow for construction.
Powerpark have set up two webcams to follow construction progress:Webcam #1Webcam #2If you do post any updates on progress using images from the webcam, please remember to upload them and not directly link the live feed, as this will cause confusion when looking back through posts at a later date!
So here's how construction currently looks; the vast majority of supports are already in place, with the track of the top hat's exit having also been erected.
