    Thank you! I really tried to model the "aggressive" stance of the locomotive. No worries!

    [MOC] TRAXX AC3 3.0

    Hello Everyone, After about two years of design, my third prototype of the TRAXX AC3 is finally complete. I built my first version in 2015 which was my first Lego train I had ever attempted to model. I wasn’t aware of any technical drawings as I had just begun the hobby, so I just eyeballed it and did my best. It was powered by two lego train motors and the technic AA battery box. After about a year, I slowly began to notice it wasn’t quite as proportional as I had wanted it to be, so I redesigned it in 2016. Since I had designed my first version entirely in LDD I had used the battery box as as structural member, which made it very difficult to replace. I was also disappointed with the performance of the train motor, so I used 2 XL motors in my second version; however, this meant that I could not accurately model the ribbing on the side that I had modeled in my first version. I made a couple of visual improvements to the cab of the locomotive including the addition of the footplates below the front lights and rescaled the windscreen. To my surprise, the XL motors did not significantly improve the locomotive’s performance; Lego battery boxes just wouldn’t cut it. I also improved the battery box accessibility and overall rigidity of the model. Although I was pleased with the improvements in my second revision, I still wanted to improve the aesthetics without compromising the performance. Up until now, I had used the standard lego PF train wheels, but after a suggestion from @jtlan, I considered using a more larger and more realistic wheel. To me, the large wheels were one of the defining features of the TRAXX, so I knew that I had to include them in my third version. I also wanted to improve the sloping on either side of the windscreen to more accurately represent the curves. I replaced the 4x1 curved slopes with angled 1x2 cheese slopes connected to a 1x1 tile with clip in conjunction with part #25893. The livery was also changed from the rather bland Railpool livery to the eye-catching SwissRail livery. Regarding the motorization, I downgraded from the XL motors to the L motors and replaced the standard lego battery box with a BuWizz. When I tested it on the rails, it was able to pull my nine 8-wide wagons with ease. The video will have to wait because my ME models track came apart due to the unevenly distributed load combined with lateral forces on the rails. Photos of older versions: I think this is my final version... for now. Thank you for reading.

    I haven't forgotten about the pantographs. It's just that my pantograph design requires minifig hands to be inserted into cut 3mm tubing, which cannot be built digitally.

    Yes it was the handrails. Honestly I have no experience with decals and am not sure what I would do when I do eventually build this model.

    Well, it's been over two years and I haven't updated this thread. I sort of forgot about the model as I hit a roadblock with regards to its design. Well during those two years I redesigned my TRAXX AC3 (which I will be sharing soon) using larger wheels. After finishing my TRAXX, I decided to redesign the Vectron using the new techniques I had learned with the TRAXX. About the Design: Although the larger wheels are more proportional, they did create several challenges. Unlike many North American locomotives, I have noticed that many European locomotives' bogies are mounted in such a way that the wheels protrude upwards into the main frame of the locomotive (Ex: Re420, Re460, TRAXX, Vectron, etc). In reality this is not really a problem because the minimum curve radius is so large and the frame's sides can be made very thin; however in lego it is very difficult to design a bogie and frame with sufficient rotational clearance to navigate even the largest of curves. I had to sacrifice a couple of details on the locomotive (ie: the recessed step below the door and the various holes along the side) to accommodate the thin side frame. I also chose to use thinner 3D printed wheels to allow for more clearance. Although I have not built the model IRL yet, I have tested a similar bogie and frame on my TRAXX with great success. Consequently the locomotive can only navigate R104 and R120 curves. It might be able to negotiate R88 curves, but I cannot test this as I do not own R88 curves. The second obstacle was the compromised structural rigidity of the frame. I ended up using the two L motors as structural members to compensate. I missed something in the second render. Can you spot it? I really have to thank @jtlan for suggesting to use larger wheels.

    Fantastic model thus far! I'm kinda wondering if those U-joints might break under the loads that you will be towing. Also, you're missing warning lights on the cab.
  7. Update 7: After much deliberation, I decided to remove all of the universal joints in the drivetrain and steering and opt for 2L axle connectors. In my previous chassis designs I have broken numerous universal joints (even the older variants) while driving outside. Surprisingly, the axles retain all of their travel even though they didn't have much to begin with (+/- 2 plates). I was also quite relieved to have chosen a springless suspension system as the model was already quite heavy even without the crane and rear outriggers. The 5th axle was quite a challenge, but nothing in comparison to the outriggers. The challenge was to achieve a small steering angle without significant backlash. First, I tried to use a linkage mechanism in conjunction with a worm drive, but the backlash affected the entire steering lock. This left rack and pinion as the only remaining option in my mind, but this system necessitated a universal joint. Below is my solution to a rack and pinion steering system without using a universal joint. The entire axle assembly rotates along the axis parallel to the wheel axles, perpendicular to the 12z gear between the the two 9L beams. Having tested the system, I can say that it works perfectly without any backlash or bump steer. Here's the completed frontal outrigger system. \ The next steps are: 1. add further support to the wheel arches 2. design a rear outrigger system 3. design a slewing mechanism

    Why don't you find out for yourself? Here's a website with a scale drawing for the prototype and production variant of the aircraft. You can copy the image's URL and use sariel's model scaler to check your proportions. You could start by defining the length [studs] (or whatever dimension you want) and see how the other dimensions compare.

    Yeah it's quite an oddity. Here are a few more that come to mind: J7W1 Shinden, Vought XF5, and XP-56
  10. I was honestly quite stumped as to why the preferences file could not be found, so I found another route to the file. Right click the application and choose package contents. Then navigate contents > resources > help. Let me know if this works?
  11. I found the preferences file in version 4.3.10 and 4.3.11 of LDD. I'm running Sierra 10.12.6 I would simply reinstall LDD.
  12. Navigate: Library > Application Support > LEGO Company > LEGO Digital Designer. You will see a file called preferences.ini. Open in textedit and add a new line at the top. Write "DeveloperMode=1"

    1. There's literally a website called 2. Manufacturer's website
