I was rightfully reminded about the weight of the beast and how to make sure it all stays in one piece. I am making headway in strengtening the chassis with 5x7 frames with 15L beams on top and below. This makes for a very stiff chassis section which ties directly to the 3x19 frame for the turntable and to the axles. To do: redesign the gearbox to the left of this image. It's quite messy at the moment because it didn't take the 5x7 into account. Also sort out the placement of the pneumatic actuators.

It's unbelievable how often the good people at LEGO forgot to pack the pneumatic parts!

I've looked at the chassis between axles 2 and 3 and noticed how sensible it would be to add a liftarm on top and below the 5x7 frames that were added recently. That way the chassis is much stronger (because it's higher) and it connects directly to the turntable with multiple pins. The next challenge is to strengthen the chassis between ales 3 and 4 in the same way. That is going to be very hard because of the gearbox and pneumatics that is currently in there.

Completely redundant, but they do look good! I've removed them from the model and re-routed the air inlet. That makes the engine more interesting to look at (in my opinion) and I can alway add the fairings later. I've also looked at the bumper, but the 42082 bumper doesn't look good to me on the square cab. So I'm going to stick with the non-42082 parts there.

Getting the structure right has been the first challenge. Luckily I was able to borrow from the 42082, which is pretty large itself. The strongest structure is needed to connect axles 2, 3 and 4. There will bear the weight from the upper structure. This is extra hard because the gearboxes are here as well. As others have suggested, I added a few Technic 5x7 frames between axles 2 and 3 (to the left of the image). Short liftarms were replaced by longer ones. I think it should be pretty good, but any ideas are welcomed.

Yeah, I can see many problems coming my way. The scale currently works out at 1:12,5 - which was based on the width of 42082. It's also quite mad. In terms of upper structure, I think the best first step is to add a 2-stage boom like 42082 has, or maybe a 3-stage boom if I have the parts for that.

I want to say it both is, and isn't. It started out as two 42082's, so you've got the axles, outriggers, turntables and chassis carried over. But then I wanted to add to the functions. There's a 5-speed transmission that I had to make room for, as well as tighter steering on the first axle. I added a few Technic frames to make that happen. And there's a gearbox that is operated by pneumatic shifters because I really wanted to, and it works best in the space. There's also a few PF receivers and two M motors because I have them lying around.... So I am afraid its evolving into a MOC that has the parts of 2 42082's.

I am an infrequent LEGO builder and I usually stick to official models even though I might sometimes brave to buy instructions for a B-model. I have rebuilt my 42082 a number of times, great! But lately my mind wondered, what if I bought a second copy? Well, things are getting out of hand. The carrier currently sits at 5400 parts in Stud.io, oops! I am able to share at the moment a couple of pictures showing the carrier and its engine details.

Love the little boat! But why did you post in train tech? Oh wait, there are bogies! I am going to guess it'll be a DB class 112, or similar...
