That's the plan. I just ordered the Trans-Light Blue version to dissect. It's a little bit cheaper on Bricklink, plus I'm hoping that being able to see a little bit through the body might help in understanding how to take it apart without damaging the pieces... If it works, maybe I could even manage an antler transplant. Brown reindeer with blue antlers?!

Hah Actually, I think there's probably enough room to hide a battery and LED inside his chest. So I could turn him into a Rudolph.

This reindeer, the molded one included in the Elf Club House and Santa's Sleigh. It looks like two molded ABS pieces with a soft piece for the antlers. Has anyone managed to separate it back into two halves? I found this guide on how to split a horse in half. But since I only have one reindeer at the moment, I'm scared that I'll break it attempting what they've done with the horses.

I think I may give this one a shot. Have you tried it before? I found some that look potentially interesting online. But as they are made for hair, most of them don't really advertise the actual dimensions... Maybe I'll order some and hope for the best.

Ahh, yes. Those previous threads are likely where I'd seen the o-ring idea. They work, but I don't love them aesthetically. (Plus as I mentioned, the ones I had did eventually begin to degrade) I was hoping someone would have suggestions for something more similar to the clear ones that come on the wheels by default now. I'll keep searching!

I thought there was a topic about this, but I couldn't find one by searching... Does anyone have ideas for suitable replacement bands for the standard powered train wheel? Part 55423. Ideally in trans-clear, and silicone -- I've tried using rubber o-rings for wheels before and they slowly dry-rot and crack.

I think the Technic hub is fairly huge, though. 8 wide by itself, I believe. So, difficult to design around.

Remember the AFOL Designer Program sets that BrickLink did last year? With Lego's recent acquisition of BrickLink, that sort of partnership would be a great way to produce low sales volume sets like rolling stock for this loco.

The 2x2 brick should fit through the 1x2 opening (sideways). If the IR receiver, battery box, etc, are not quite fitting in your train, you might consider the new Powered Up version. The motor connects to the battery box on the side instead of the top, and you won't need to worry about the big IR receiver either as it works over Bluetooth. I also stumbled onto this site after I posted. I don't know anything about them but they look like they are based in Europe, which would probably be much faster/simpler delivery than the US one.

You could order a 6x28 with the 2x2 holes from BrickLink, part 92339. But I just checked a PF motor cable and it fits through the 1x2 hole in part 4093. Maybe I'm not understanding your problem, but it seems to me that what you already have should work without needing to be drilled? The stickers, you can get replica stickers for the set and put them on whatever parts you choose. I found these stickers from OKBrickWorks for your set on eBay.

What is that crossing track?

This is very nice, thanks for sharing.

This link to a discussion on the pirate forum suggests a size of 1920x200. Looks like the picture will be center cropped for users with smaller screens, so items at the center of the image will be preserved with the edges being discarded. Current in-use banner images appear to be a mixture of PNG and JPG.

I've put the design files up on my GitHub now.

@Henry 991, wow, those are beautiful wheels. I never would have guessed they were 3d printed!
