Modulex manuals, brochures and catalogues

We wanted to tell you about a new online resource that collates various historical printed information about Modulex. If you’re unfamiliar with Modulex, it was a separate building system that was introduced by The LEGO Group in the 1960s, intended for scale modelling and project planning.

The Modulex Library has been collated by Ryan Howerter, including scans by Karyn Murphy, Bailey Fullarton and Karwik. Please note that the site is not affiliated with The Modulex Group, and that the scans are archived for historical reference only and are not to be used commercially. 

Old Elementary: the Train Light Prism

Following his stunning contributions to our recent LEGO® Parts Festival, the talented Swedish builder Oscar Cederwall (Flickr) suggested he write an article about one particular element he used in one particular build that a lot of you have been asking about. 

You might have seen this MOC of mine before. It showed up in the New Elementary Parts Festival in late 2019. When you saw it, you might have wondered what those weird parts that make up the cockpit are? Well, let me tell you all about them…

The story about the Electric, Train Light Prism 1 x 3 (Design ID 4171), or "train prism" that I will call it hereafter, begins in 1980 with the new LEGO electric train system. The part was released in six sets during a seven-year period, and only in Transparent/Trans-Clear. Just three of these sets are actual trains; the other three are accessory packs.

Old Elementary: Ralf Langer's Modulex MOCs

Ralf Langer is a German builder who seems to have a real knack for integrating Modulex into his LEGO® creations. This is the second article in a two-part series; read the first part detailing his Modulex-to-LEGO connections here.

Combining the techniques from my previous article, let's see some real life examples of MOCs that were not built simply to show off a single technique.

For this building, I used the linked tile bricks technique for the window arches. The rest of the window frame is made out of Modulex 1x3 tiles that are held by some Plate 1X1 W. Upright Holder.

Old Elementary: Modulex and LEGO® brick connection techniques

A year ago we published an article explaining what the old LEGO® product called Modulex is, its history and useful resources about it. There were mixed reactions to the article, primarily because Modulex is incompatible with the LEGO System bricks we all know and love. Or are they? More recently we came across Ralf Langer, a German builder who seems to have a real knack for integrating Modulex into his creations. Ralf was happy to offer some insight into his methods.

I bought my first Modulex bricks back in June. I'm not quite sure why I finally decided to give it a try but most probably they were terracotta, a nice muted earth tone. I really like using muted colours and the Modulex colour Terracotta is a tone that seems to be suitable for roofs or decorative strips for houses.

2017 Skærbæk Parts Festival: Cristiano Grassi and Oscar Cederwall

Two participants of our parts festival at Skærbæk Fan Weekend last September continued building with the new LEGO® pieces after they got home from Denmark.

Oscar Cederwall

Oscar was very interested in the strange Minecraft railway track piece, Plate 2X2, W/ Design in Reddish Brown (Element ID 6163991|Design ID 27928).

He pulled some crafty moves to set the whole of the interior of this flower box at 45°.

Old Bricks: What is Modulex?

Back in the 1960s the LEGO Group created a new kind of brick, for adults. LEGO® history geek Francesco Spreafico has kindly agreed to translate another of his great articles for us, which he first published in Italian on his excellent blog Old Bricks.

In past articles I mentioned Modulex bricks a few times, but I never fully explained what these bricks actually were; I think that now the time has come to write a brief introduction about them.

History of LEGO Modulex

At the beginning of the 1960s Godtfred Kirk Christiansen had to design a real building and, as an extension to regular drawings, he created a physical model of the building using LEGO® bricks. Since he had found this process to be very useful, he decided to have a new system developed, a system that was not compatible with the LEGO System, but that was optimised for this kind of architectural design. These new bricks – the Modulex bricks – were put on the market in 1963 and they were intended only for architects, the category they had been created for.

Old Bricks: Brick Yellow & Brick Red

Francesco Spreafico returns with another guest post today containing more interesting historical facts about LEGO® colours. Francesco first published this article in Italian on his excellent blog Old Bricks.

About a year and a half ago, Kevin Hinkle of the LEGO® community engagement team told us a bit of trivia he had heard from his colleagues in the Materials and Research & Development department: the reason why the LEGO colour that is commonly called “Tan” is officially called “Brick Yellow”.
