Yeah, it almost works 🙂
The tough thing is the squares by the "finishline". They need to be even, and the start squares needs to be "uneven"
Then you need to do it with art brushes. Design them in horizontal orientation in the way they need to be. Do not outline the paths before creating the brush. Open the paths at one point before applying the brushes.
There's a slight irregularity at the start and end point. You have to expand the brushes and then fix that afterwards.
You have given yourself a tough task because of the constraints and inbuilt irregularities, much tougher than the case Ton linked to, but ultimately of the same kind.
It can be done, with a combination of Offset Path (Object), Compound Path (Object, or you can use minus front in Pathfinder)), Blend (Object, used twice), a guide line for the finishing line (over the Anchor Points at the end of the straight part, Smart Guides) and double guide lines for each set of start squares to form a bonding pattern (I have no clue what this bricklayer term is in Swedish), and ultimately Dashed Line (Stroke, used countless times, first once and then thrice for each track, Stroke Weigh equalling track width, Dash equalling the Stroke Weight of the track borders, and using Adjust Dashes to fit) just as in that other case. Everything ending with removal of the double guides and adjusting the position (and/or increasing the width) of the red finishing line to cover the whole set of Dashes there.
And all the way, Smart Guides are your friends, telling you when you are within snapping distance for accuracy.
You can search for the terms mentioned here, just insert each at the top,
The image below shows the steps on the way, from the beginning and as far as the 1st and 2nd track finished, 3rd - 6th track being finished in the same way, alternating between the double guide lines to form each bonding pattern. The proportions are different to those of your image; I just started drawing to make sure all steps were included.

Thanks.... I´lll get to it and try 🙂
You are welcome, chrisnils.
I have just made some additions, maybe more are needed; you can just ask if you get stuck, maybe most convenient with screenshots including relevant panels.
I for one hope you will report your findings.
