How many degrees of slant can a train in the TSW (423 or 422) handle. As a test, I currently have 5° for the Stuttgart S-Bahn to the HBF low. Wie viel Grad schräge, kann ein Zug im TSW(423 oder 422) Bewältigen. Ich habe im momment Testweise 5° für die S-Bahn Stuttgart zum HBF Tief.
If you convert 5° to percent that's around an 8-9% slope which is too steep. DB Infrastrukturregister says 3.5 to 4% for that stretch I think Berninalinie or maybe Arosalinie take the cake for steepest route in TSW and they are around 7.5% at most I believe.
fceschmidt is right. Though, you want more precise data, you can see the gradient profile, which says the gradient is around 3.78 % on the Gegengleis and 3.7 % max. on the Richtungsgleis. In front of the parenthesis is the slope in permille and inside the parenthesis is the Streckenkilometer.
If you want the model as precise as possible, you can make the ramps precise with the correct gradient data as provided by fceschmidt and Lulon in Blender. However, you also could do the job in a different approach, which gives you a bit more flexibility I think to adjust the ramps afterwards, and this is probably what I would do as well: Leaving the ground completely off and just keep the side and top surfaces of the ramp entries. In this way, you shape the ground (the actual ramps) by sculpting & shaping your terrain instead. If you're handy with the tools in Landscape mode, I think this gives an advantage to just form the gradient of the ramps within the Editor and the gradient would be too steep for any of your locos you can change it in the Editor. As a sidenote to add, if you have high-resolution Lidar for your route available (also needs to be quite new on for Stuttgart Hbf), the terrain ramps to the Tiefbahnhof should already be in the landscape. So you might just need to do a few adjustments to smooth the surface of the ramps into the underground.
That's a really good idea! I would do it like that too. To add to the last bit. I don't know if Lidar is free in Stuttgart, but Stuttgart is in 3D in Google Earth, and you can actually download the Google 3D models. I don't know of an official and at the same time free way but you can use RenderDoc to download areas. There is also a YouTube tutorial about it. Then you could use that as reference for all 3D modelling. I would definitely take advantage of it.
I have now tested the 423 and 422 on Rapid Transit on the ramp to Leipzig HBF underground station, the ramp has 4.0%. I have now changed the ramp from Stuttgart to 2.8°, which should be approximately 5.0%, it should work. The two ETs easily manage to reach 4%. Ich hab jetzt den 423 und 422 auf Rapid Transit getestet auf der Rampe zu Leipzig HBF Tiefbahnhof, die Rampe hat 4,0%. Ich hab jetzt die Rampe von Stuttgart tief auf 2,8° geändert, ungefähr sollten dass 5,0% sein, sollte ja funktionieren. Die beiden ETs schaffen die 4% locker hoch zu Fahren.
