7750 "ideas" builds

[Reker1000000]

Hello EB,

I am proud to say that I've acquired a boxed 7750 recently, which I was waiting on for a while. Looking at some of the beautiful pictures on the box, I'd really like to build the alternate models beyond the B-model featured in the instructions. However, I cannot find instructions for any of them online. Could anyone guide me to instructions for them, or offer some tips on reverse-engineering them with the given pieces in the set?

I found this video which features the A-model and B model plus 2 out of 3 of the models shown on the box.

Hi there!!! Nice buy!!!

If you can provide the pictures I can try to do some reverse engineering - I do not have the box, unluckily, and I'd like to recreate these alternate models since I've seen this video some time ago.

Plus, I'm really really curious about the medium wheels depicted on the box - they seem a "prototype" more based on old 1970's train wheels than on 1980's!!! 

Ciao!

Wow I didn't think there were users with more than one 7750 set! 

Gorgeous video!

A few links (hoping they work, if they don't let me know):

Here are photos of the front and back of my box, with close-ups of the "ideas" photos.

Plus more photos of the specific set I scored. Of course including all of the heavy hitters (red motor, black windows, bogie plates + wheels) are present plus a number of semi-valuable parts. And an entire set of stickers, including the one on the back that I have not heard of anyone else knowing about... I'll make a new topic specifically on this and the 7760 at some point soon.

Funny enough, everything about this set is great but the motor is broken  so a replacement one is on its way from Switzerland. Extra points to the seller for fast communication and a fair solution. The motor you see in the pictures is actually one donated from my 7730.

Finally, a link to a video featuring the train running on my third featured layout (check my YT channel!) with 7730's wagons (read the description for a cool piece of history on this specific train...). You might see the dismantled engine of 7730 behind the 7745 and 2 spare motors (1 black, from 7865, and the broken red one) off to the side.

I actually think that the photo on the bottom left of the front of the box depicts a model that you might be able to build with real bricks but won't work physically. Based on the picture I think the black steam cylinders would prevent the motor from turning, although I may be wrong. Plus, it needs to use 3 2x8 black technic plates with holes while the set only includes 2.

Yeah, based on observations on various boxes I'm pretty sure they made at least some of the art for the boxes before actually finalizing the design on sets and producing final parts. I'm sure they used inspiration from the 70s train sets for these wheels originally, although I don't know why they would have changed them.

Just ask Reza- In addition to several copies (some boxed) he's got one sealed. What I wouldn't give for a MISB 7750... Maybe someday! Although, I don't know what I would do with sealed. I'd want to immediately open it. In fact I ordered recently a sealed 7862 for a very good price and I intend to open it and post to YT!
