And so the big moment has arrived, the one that we have all been excitedly anticipating for weeks: the first supports and tracks are being installed. The most difficult part comes right at the start, as the tracks are installed in the tunnel. This process becomes very complex, as a crane cannot be used to suspend the track sections in order to assemble them – and when each track section weighs around 4 tonnes, putting them together is no mean feat. In addition, supports are assembled on the tunnel. These supports have a special shape in order to distribute the load to the walls. Further assembly areas include the first drop and the inside of the station, where the single 2-bar rails are being installed. One thing is for certain: the excitement is set to continue over the winter months, so we’ll keep you posted!
At the same time, the conversion, extension and elaborate decoration works in the station are advancing. Eventually the waiting area shall convey an authentic first impression of the fun “Dynamite” riding experience. And it goes without saying that we are also going the extra mile for you when it comes to the theme. Following the gutting of the old Silver Mine entrance area, things are progressing quickly in this regard, too. In a laborious process during which great care and attention was paid to the details, we gathered together theme-appropriate decorative features from across Germany, including an old sawmill near Cologne.
The wait is finally over: it’s time to hit new heights! Filling a remarkable 30 HGV loads, the first elements were delivered for assembly. Along with screws and connectors by the box-load, other parts were also diligently unloaded: the signal-red track supports for our new family roller coaster, “Dynamite”, the brackets for the supporting bars and the supporting bars themselves have all now reached their final assembly location.
And because we have couldn’t take the excitement any longer, we went on short visits to MACK Rides in Waldkirch in the snow. There, the production of the ‘Dynamite’ tracks is in full swing. The triangular connectors have been prepared, as well as the first elements of the three point tracks and the accompanying bridges for the lift in progress and if everything goes to plan, the big delivery is due at the end of October here at the park. Then from November, there will be nothing to stop assembly. Fingers crossed that everything goe sto plan. We will keep you up to date!
The last work on the transfer platform and the maintenance hall is coming up. A coaster can be driven into the maintenance hall via the transfer platform depending on the number of visitors and drive ‘Dynamite’ with minimal waiting times in a need-based way with one or two coasters. Various maintenance work on Germany’s first Big Dipper Coaster is being completed in the hall. The station is also getting its last foundations.
Then the final foundations in the looping and lift areas are already pending. Particularly at the beginning of looping, the foundations are exposed to exceptional strain and accordingly must be laid deep. Here, our team will of course not allow themselves to be stopped by such a gigantic discovery as this 30 tonne boulder.
Selbstverständlich kommt auch in dieser Bauphase das Theming nicht zu kurz. Um allen Bereichen von „Dynamite“ den thematisch passenden individuellen Look zu verleihen, geht es im nächsten Schritt an die Verkleidung des Tunnels und der Überfahrt. Als Reminiszenz an die alte Dame „Silver Mine“ wird hier das ein oder andere Element unserer alten Familienachterbahn ein liebevolles neues Zuhause finden. Am Bahnhofsgebäude finden Holzarbeiten statt und auch die Helixzufahrt wird bereits teilweise verkleidet. Das alte Bahnhofsgebäude der „Silver Mine“ wird aufwendig saniert und zukünftig als Eingangs- und Wartebereich für „Dynamite“ seinen neuen Aufgabenbereich finden.
Und so sieht es aus, das Layout von Deutschlands erstem Big Dipper Coaster "Dynamite" - ab 2019 bei uns im Freizeitpark Plohn. Hier schon einmal ein paar On- und Offride-Impressionen zum Vorfreuen.
We are well on schedule. The construction of the tunnel to our German premiere is making progress in leaps and bounds: The tunnel roof has already been clad. The next step is the completion of the concrete layer for the top. On the way to Westernplatz you can already see the impressive tunnel construction.
Of course, theming was also very important to us in this construction phase. Without the typical ‘Plohn style’, things would not work here. The tunnel to the mine is getting its first expensive accessories: turbine, transmission shaft, water wheel, steam engine, all decorative elements brought together in keeping with the style and in loving detail from the whole of Germany. So our construction site enters its summer break. In the holidays there are no longer any limitations from construction work. In Autumn things will get rolling. We will keep you updated.
Up next is the beginning of construction for our railway station. This means: Base layer of concrete up to the rocks, deeper foundation, then cleanliness layer. Then we proceed with applying the concrete to the top and cladding the walls. The side walls for the marshalling yard for the maintenance hangar are already in progress.
The construction of the individual foundations presented particular challenges due to the particular soil properties at first. But now swift progress is being made. The foundations for the looping are on the agenda, with the enormous centrifugal forces in curves and looping, stability must be guaranteed in all directions. The support wall for the tracks provides additional stabilisation.
We now move on to building more than a hundred individual foundations, the foundation stones for the subsequent track route of our premiere in Germany. Each foundation will be given its own support shape depending on the respective precise load of the foundation. An unbelievable amount of power is released in Dynamite’s sharp curves. Each foundation is dug after being examined and recorded separately.
Caution: explosive substance! Germany’s first Big Dipper Coaster isn’t the only thing that’s going to be explosive: the roughly 120 individual foundations cannot be built without dynamite. The bedrock surface is higher in some places in the area of the former silver mine, due to which blasting is necessary. Several boreholes are being made and around 350 m³ of rocks blasted. The sound of the huge explosion resonates through Plohn and its surroundings.
The construction of the tunnel for our new major attraction is beginning to take shape. The walls are being built and put up, which will be followed by the ceiling formwork and the casting of the ceiling. The tunnel will be an impressive 7 metres wide, 7 metres high and approx. 25 metres long for Dynamite. Stability is our highest priority because there is still more to be done to the tunnel - we’ll keep you guessing.
The construction work on the tunnel begins. A total of more than 200 tons of steel is used, as reinforcement for the foundations, among other things. The floor slab for the tunnel alone devours some 300 m³ of concrete.
The preparatory earthworks for the tunnel begin. Enormous masses of earth have to be moved and transported away for this purpose.
Now comes the construction of the foundations. In order to guarantee 100% stability each individual footing has to be put in place right to down to the rock 7 metres deep, including 6 metres of oversite concrete. Every frost-free day is used, in order to maintain the production schedule.
The access to the construction site has been prepared and new space created. A few preparations for earthworks up to 7 metres deep are needed, before things can finally get started.
Goodbye Silvermine: our venerable roller-coaster is going to a well-earned retirement. It will be divided into individual segments. Possibly one part of it or another will turn up in a new location in the park, who knows?
