TrixBrix Track Library for Bluebrick

I have compiled a complete track library with all TrixBrix tracks for the track planning software Bluebrick. The library contains more than 200 tracks, switches, crossings, special elements and sets. All geometrics have been calculated with full mathematical precision.

Some examples:

4. On the next screen, select the TrixBrix Library for Bluebrick ( and click “Start Download”.

Bluebrick will then download the library. Click on the “TrixBrix” tab on the track element section to use the library.


After downloading the library, it is a good time to optimize your Bluebrick configuration:

  • The TrixBrix Track Library for Bluebrick works best on white background. Navigate to menu “Edit / Preferences”. Select tab “Appearance”. Choose Color Scheme “Classic (printer friendly)”.
  • Stay in the preferences dialog, as we need to do some additional settings there. Select the tab “Part Library”. Select “TrixBrix” and move it up to the top of the list by clicking the “Move Up” button.
  • Still in the preferences dialog, find the box “Part and Bubble Information”. Check “Part Info:” and “Description”.

Tips and Tricks

In the library, there are some “sets” of predefined combinations of tracks, e.g. railyards, cross-overs, and pass-throughs. Add one of them to your layout, e.g. the “Monster Crossover R104”. You can disassemble a set by clicking the right mouse button on it and select the context menu “ungroup”. After ungrouping, you can move the single components of sets individually.

  1. Hello,
    I have a problem: Ican’t download the TrixBrix parts library. How can I have this?

          1. Hello, I could download the files, but the sections of the library in Bluebrick are empty. In the downloaded files, the icons do not look like the other parts. There is no folder named “config”.

          2. Hello, I download the 1.9.1, and it works. Thanks for the help. Have a good day.

    1. There presently is a problem on the Bluebrick server. We have informed the Bluebrick developer. I am sure that it’s going to fixed quickly. Please recheck in a couple of days!

  2. Hi Matthias,

    I’m still not able to download the library. It still gives an error when starting download. Can you maybe put the url where to find the library so i can try manually?

    Thx in advance.

  3. Hi Matthias,
    I encounter the download bug again within BlueBrick. (But I could download and unzip the Trixbrix library manually.)
    My real question: where in ANY library do I find the standard LEGO switches from 60238? I already have some of those and would very much like to incorporate those in my ‘project’. Thanks!

    1. Hmm, a good question. Obviously, the 9V switches and the Trixbrix R40 switches with the parallel track adapter have the same geometry as the switches from LEGO 60238. What you can do is to copy the 9V switch and rename it to “Standard switch right/left” or similar.

  4. Hallo Matthias,
    Download und Installation haben soweit gut funktioniert. Danke für die tolle und verständliche Erläuterung auf deiner Website sowie auch auf YouTube.
    Ich habe allerdings ein Problem. Ich habe bei der Gleisplanung keine Verbindungspunkte (gelb) die zu sehen sind, sodass sich die Teile nicht miteinander verbinden.
    Hast du einen Tipp wie ich das Problem lösen kann?
    Danke & beste Grüße

      1. Danke Matthias für die schnelle Rückmeldung.
        Den besagten Menu Punkt hatte ich mehrfach angeklickt, leider ohne Ergebnis.
        Heute alles gelöscht und neu installiert, jetzt funktionierts es einwandfrei.
        Vielen Dank & beste Grüße

  5. Is there anything available like Blue bricks I can install on my android tablet, I do not own a PC and would love to be able to design layouts to help my Grandson
