We are standing here at the 25m test track for the bridge that will lead to the South America section. As you learned from the last video, the bridge has a slope of 3%. We recreated the slope to better test the trains. High-speed trains are supposed to run there, so we have already tested the TGV and the ICE 4. But they're too slow for us. So now I'm starting to tune the trains so they go faster. The first thing I do is pick out trains that can be used for this and then start rebuilding them. I chose a TGV. From the size and appearance, it looks perfect. I will also open the train and look at it from the inside, because the engines need enough space. One advantage is that the train has no windows in front. That's why you won't see the modification later. It wouldn't be nice to see the new engine. With the ICE, especially the newer types, you wouldn't have that, which is why this locomotive is ideal. That's why I'm really happy with this locomotive. Now we are standing on the bridge that connects the two buildings. That is, the existing Miniatur Wunderland with the new section South America. The two buildings are of different heights. Accordingly, the bridge has a slope or an incline, depending on the perspective. What we're doing right now is leveling the slope so the trains can do it and that they go fast. It's all for this bridge we're standing on right now. I think the bridge is really fascinating when you see it from the outside or when you stand on it. It will be a highlight for the guests, I'm sure. I have removed the cover of the train so that you can see the inside. You can see the original board and the motor, I don't need all that. The next step is removing all of this. I want to have as much space as possible in the train to accommodate a new engine and new technology. The rest would just bother me now. Now you have seen how I took the train apart. Now only the chassis is left, the rest has been removed. The gears here are... The old engine... This will be the new engine that we install. Before I can do this step, I need to mill out a little bit of the floor first. The new engine won't fit otherwise because it's bigger. That's what I'm going to do now. The rebuild of the train I'm doing right now is just a rough test. A train that later also works in continuous operation, we have, after all, at the normal exhibition. You have to remember that the trains are actually toys that are not suitable for our continuous operation. That's why, for example, there are the cooling times of the trains when they go to the shadow stations to cool down. When they have cooled down or the next train arrives, they go on. This experience also benefits us here. As you have seen in the time lapse, I have finished rebuilding the train. I rebuilt the old cable shafts so that I could use them for the new motor. I had to make new bushings for this. Then I built a wagon that contains the speed controller for the motor. It also contains the signal receiver for the remote control, because for now we are using just that. If we decide on a motor later, we then consider how to integrate the signal into the speed controller. I don't need that for the test drive. The difficulty in rebuilding the train is that the original gears are not designed for our load and speed. We can install engines with higher revs, but that would damage the gears. This has already happened to me a few times. We are currently considering whether to build the gearboxes ourselves or have them built. Now we have arrived at the test track with the train and the control system. We'll be doing test drives soon. We start slowly with the equivalent of 50 km/h in 1:87 scale. It is also possible that the gearbox will break right away because it is not designed for the forces of the engine. I hope for the best and will start right away. As you can see, the test worked out great. We drove the equivalent of 800 km/h. Nothing broke either, not even the gearbox. I wanted to achieve 600 km/h, which is why I'm super happy with 800 km/h. That's good, so we don't have to drive the system to the maximum later. We can stay below that, which protects the engine and the components. The step-by-step acceleration also worked very well. As in the original, you can't just say you're going to go full throttle within a second. As with a car or a real locomotive, acceleration is slower. As in the original, we want to recreate reaching the final speed at some point and then slowing down. That works really well. I hope you enjoyed the video, it's a very interesting project for me. I'm looking forward to new projects and hope to see you next time!
