@Sjoerd, looks good, can't wait to test it. :D
Nicolas wrote: 07 Apr 2023, 18:20 Is there any footage of the BOA 001 in movement? There's barely any info on this peculiar train on the internet, besides a Wikipedia article in French. What an odd thing, especially the gangway made of two separate frames with windows and three cushions.
Indeed, even the wiki page is pretty thin, after being the star, 'the prototype of the 2000s metro', it's direct successor, MF88, ended up being very fragile and the orientable mono-axles being a not so good idea, very aggressive for tracks and trains.
In the end RATP preferred to scrap it without communicating too much.

I'll try to give a few infos, links and images anyway :

First, the BOA were only a prototype train to test, among other few things, mono-axle 'bogies', at first it were not supposed to take any passenger (as we can easily assume :D) :

From Twitter @RATPgroup
On this image it has 3 cars, still have a MF67 bogie on both ends, and we clearly see it's based on MF77 cars.
Notably, you can see how the roof were shorten, to be able to test it with rubber tires (the system would have looked like VAL trains).

But after a few years, the prototype giving good results, it were decided to rework it and make a passenger-compatible train.
Ended up with 4 shorter cars, a total of 46.34 meters, the bogies that were still in place are replaced with a mono axle + guide axle (the guide one only reading the track to lead the rest of the train).
Here it is in 1987, being refitted with it second skin :

Another shot where you can see it in 1990, right before the beginning of it's tests with passengers on line number 5:

As the prototype were an opportunity to test different types of intercirculation, first on the left, the most complex, based on RATP patent and provided by Alstom (Alsthom at the time), with 2 rigid parts with windows and 3 small rubber/metal bellows (on the left) and another one by ANF with long bellows made of short rubber/metal curves (basically what is used on articulated bus adapted for metro, on the right on the image) :

Sadly only the Alsthom one, the closest to the "uninterrupted train" never made it on another metro (though it's patent is used on the Citadis trams, on the parts without bogies where the car is maintained by it's two neighbors).
The last one is made with large elastic rubber loops, made by Faiveley :

Here is another french speaking page :

About the videos, I did found a few pictures in motion but to be honest I can't get my hand on it again. :?
One was a (kinda ridiculous) video clip with David Getta, the set was in front of the Boa, nothin rolling, simply people dancing in front of it (don't ask me why :D )
One was a very long Italian TV report on trains and urban networks around the world, it shows the BOA rolling on test tracks (the image with the panto is a screenshot I made from it, I still must have the full video somewhere but I can't find it).
And the last one is a short french TV report showing the BOA moving outside Vaugirard workshop.

If anyone have a link to any of these feel free to share them. :)

Finally, the direct descendant of the BOA is the MF88, it still operates on line 7bis but will be scrap in a few years because of it's fragility.
You can see and hear it over here : https://youtu.be/I2vqhO-2kqI

I was thinking about making a long message to show how I build a train from scratch until I export 3D meshs for Sjoerd, if some of you are curious, I'll do it. :)

3D meshes ? Does that mean that if the technology is available, Paris routes will come? It's just a guess on my part and I don't spread rumors about such things.

Any shape made in 3D is called a mesh, so every train part, every object moving or not is a mesh.
More infos here : https://en.wikipedia.org/wiki/Polygon_mesh

About a Paris themed map, nothing is in the pipeline one my end.
For now, I work on finishing the exports for MF77, BOA is about to be exported as well, no clue about what I will work on next. :)
