[WIP] Fuori Muro Vectron

Recommended Posts

Hello Everyone,

Over the last few months I have been working on my vectron in LDD. The main purpose of building this train was to be able to fit 2 xl motors (with gearing) into one unit. I finished the main body, but it looks a bit off and I'm not sure exactly what proportions are wrong. Any suggestions or ideas are very much appreciated.

Here's what I have:

The vectron locomotives have a slight slant to the front panel just below the windscreen, however I decided against making it since it would just make the model weaker and add unnecessary complexity, in my opinion.

Here's what the inside looks like just to give you an idea of the space (or the lack thereof) I have.

Specifically, what dimensions are wrong? 

Thanks for reading

Building a proportional model without a scaling drawing is like working blind. However, overall you seem to have done pretty well. I made a scaling drawing to figure out where the discrepancy is:

Click here for full size.

The gist of it appears to be that, at the scale you're building at the Vectron's wheels are closer in size to Big Ben Bricks' medium drivers than they are in size to the flanged wheels. In fact, we could have discovered that by scaling down Seimens' quoted size for the wheels by the scale you appear to be using...

In LDD, try substituting this arrangement for a medium driver:

(Note: the hole in the medium driver is not the same distance from the axle as the holes in the pulley).

Let me know how it goes.

I was thinking the same thing ... maybe the medium BBB wheels are too big but they seem to be the right ones, otherwise it would be recommended the use of standard lego motor 88002.:classic:

The MOC is amazing, body and nose are ok! :thumbup:

Thank you both for the replies. 

With regard to the wheels, I decided not to use BBB med because the wheel is partially covered from the side, which would restrict the bogie's rotation. I would have to raise the bogie by approximately two to three plates to avoid this problem. Instead, I scaled the height from the bottom part of the wheel that contacts the rail to the bottom of the superstructure.

I have used your scaled drawing to rework the loco. BTW, where did you find the lego grid to overlay onto the image?

Here's what I have so far:

I'm having trouble getting the front part below the windshield right, which needs to be 2 bricks tall. The part below the light needs to be about one plate. The light itself needs to be one brick tall. Yet all of this must be curved as well as slanted while keeping the blue stripe at the same level. I tried to solve the problem to no avail. If you have any advice please comment. I would really appreciate it!

I also put the LXF in my bricksafe if you'd like to try to tackle the problem.
