I've been split in scale since I began building LEGO trains with all my shunters, freight wagons and latest passenger train being 7-wide or 1:54 and all my older locomotives and passenger wagons being 6-wide or 1:60.

With almost all of my buildings close to true minifig-scale, I've been contemplating to unify my scale for a few years now but I couldn't decide to go for either 7 or 8-wide...in addition to being pretty much satisfied with most of my 6-wide models as they are.

Well, no more :grin:

Presenting my favourite Danish State Railways’ (DSB) locomotive redesigned to 8-wide and digitally rendered in two versions and liveries...


DSB Litra MZ

The powerful Litra MZ locomotives were built by Swedish Nydquist & Holm AB (Nohab) and Danish subcontractors on license from General Motors.

10 MZ (I) were built from 1967-1969.
20 MZ (III) were built from 1972-1974.
61 in total were built across all four variants (I-IV).

Quite a few are still used today by private railway companies either domestic or abroad, in Iran, Norway and Australia.


My model of DSB Litra MZ (I):

DSB maroon livery used in the 1960/70s with the highly recognizable crown and wing logo on the front.

Scale: 1:46
Length: 56 studs from buffer to buffer
Width: 8 bricks
Bricks: 1.264
Powered: 2 x L-motors, 2 x AAA battery boxes + 2 x SBricks, 1 x AAA battery box + 1 x SBrick/PFx Brick or 2 x BuWizz battery boxes
Control: PF with SBrick, PFx Brick or BuWizz
Designed: 2020

All renders are done on the very high setting in Stud.io with all of my own custom decals added in the PartDesigner tool.

3-axled bogie:

The center wheel will utilize a black hockey puck as a blind driver or a 2 x 2 round tile with open stud and 1 x 1 round tile placed on top on it as the alternative.

My model of DSB Litra MZ (III):

DSB "modern" red & black livery used in the 1980s.

Scale: 1:46
Length: 56 studs from buffer to buffer
Width: 8 bricks
Bricks: 1.331
Powered: 2 x L-motors, 2 x AAA battery boxes + 2 x SBricks, 1 x AAA battery box + 1 x SBrick/PFx Brick or 2 x BuWizz battery boxes
Control: PF with SBrick, PFx Brick or BuWizz
Designed: 2020

Part of the fun and what set LEGO trains apart from pure model railroading is the inclusion of minifigs, so whenever and whatever I always try to make space for them and also keep on some play features and interiors.

The 8-wide body is quite roomy and has a fairly correct interior.

2 x PF L-motors with either 2 x AAA battery boxes + 2 x SBricks, 1 x AAA battery box + 1 x SBrick/PFx Brick or 2 x BuWizz battery boxes can be utilized:

Technical addendum:

For the first time ever I have used technical drawings overlayed with LEGO scaled grids to get the dimensions right or as close to right as possible.


50157370776_11e588f595_b.jpg


The models haven't been built yet but some smaller builds have been used for testing during the design phase.
My slightly shorter test train didn’t really like driving through R40 curves, no surprise there :blush:
Too much length overall and the wheel sets in both ends of the bogies are also pretty far from each other producing some drag. 
Going through isn't impossible though but rather uneven and a tiny bit struggling, especially with added wagons.
There are no problems driving on straight tracks and through larger radii curves.

To my surprise however was the finding that the total number of parts were the same or even slightly less than a similar 7-wide model :oh:

So henceforth, 8-wide it is :classic:

Wow, this is fantastic. 

I can only speak for myself, but I believe 8w to be the best compromise between part count and appearances.

Yes, very nice builds. I like both versions. The high level render and decals make the models come to life, despite beeing "only digital".

I love the colours of the older version, I think it fits and emphasises your work on the shaping (especially around the cab) far more than the newer scheme. Excellent work!

Very much agree.

What part did you use for the fans on the roof? Are those the base of 4x4 turntables? If so, what's in the middle?

Interesting point :thumbup:

I prefer the red and black but that's probably nostalgia talking :laugh:

These are a great build, the motorization is particularly fascinating, but getting that slant on the top of the sides looks like it was a real challenge.

If you want to do away with the technic disk and just use the turntable base you could always do something like this

You did an outstanding job capturing the look of these, well done.

I started working at GM-EMD when these locos were ending their production; as the noise engineer I recognized these for their quiet, isolated cabs which we didn't do at EMD until about 20 years later. The fact than Nohab could package a 20-645 engine on six axles with dual cabs at the total weight matching a North American 4-axle loco is impressive.

Regarding the cooling fans, I've thought that Big Ben should tool up to produce a part matching the EMD 48 inch fan since it was widely used and the sticker approach or the blind driver approach doesn't quite do it. Maybe Zephyr could produce a 3D printed fan to add to his offerings (I suggested it to Ben already and he didn't think there was a big enough market), I can provide a 2D drawing if anyone is interested.

Really amazing. I followed your work for a couple of years now, but this 8-Wide ads really some topping on the cake.

Although I am not convinced of 8-wide for my own models yet, I would possibly try to rebuild your dark-red variant just to see and compare to 6-wide and than rethink my preferences :laugh:

 

Question: Why haven't you used dark Brick 1x2 with Grille 2877 for the older variant? I think that would look even better?

The horror 😱😱😱😱😱

That part finally produced in dark red and I hadn’t noticed, so thank you for making me aware of it 👍

Now I need to make some new renders 😁

Thanks :classic:

The slant wasn't that big of a challenge as I had already tried numerous approaches during the evolution of my older 6-wide version :classic:

The two main challenges for me were: 

1) The curvature along the side edges on the front. 
Hard edges were neither correct nor looked good (too boxy), curved slopes sideways were too flat and placed the curvature in the wrong places (either on the front itself or too far back on the sides) and curved bricks sideways alone gave the appearance of fat chubby cheeks with too much of a gap between them and the 6-wide train windscreen.
Cam (one of the Brick Train Depot guys) helped with different suggestions and everything quickly fell into place after that.

2) The bogies.
In particular the front proved rather difficult with the continuously lower front part and the slanted brick-built plow which both had to move together with the turning bogie necessary for navigation curves.
This took some time (and several failures) to figure out how to do reasonable solid and look both good and correct.

I really love this MOC, and I have to echo that 8-wide seems to be a really good scale for LEGO trains (at least for standard-gauge anyways, I use 6-wide for my narrow-gauge stuff).  I also have always been a fan of the DSB locomotives ever since seeing the MX & MY, and this one is no exception.  I'm hoping to make a trip to Denmark sometime in the next couple of years and plan on hitting up some of the Danish railroad museums/heritage railroads when I'm there.

Thanks, Laura 🙂

If you do visit Denmark, please find time to visit The Danish Railway Museum in the city of Odense.
The museum is well worth a lengthy visit 👌

The former Odense Banegård is right next door to the roundhouse housing the museum 😁

I'll definitely do that, especially since Odense is fairly close to a castle (Egeskov Slot) that's near the top of my list of points of interest to visit in Denmark.

All renders updated with the Dark Red 1 x 2 Brick with Grille which I would have used in the first place had I known the part had become available in that color 👍

I had already admired them on Flickr. Really nice model!

I recognise the black and red livery from various trips to Denmark but the classic one is more... classy? I'm not a fan of most modern railway liveries. I've never liked the DB 'verkehrsrot'. Pretty much every German loco looks better in whatever colour it was before that was introduced...

Haven't been to Odense for a while. Let's see if I can convince Mrs. Duq to visit the museum next time we're in Denmark.

Dennis - I've really enjoyed watching (and helping) these come together ... I still think the maroon Litra MZ is my favorite.  I can't wait to see it pulling those coaches you've been working on!

Scale: 1:48
Length: 62 studs from buffer to buffer
Width: 8 bricks
Bricks: 1.226
Wheels: Ball bearing type
