Welcome Benoit, looking forward to read more about this project. Phil.

A more realistic LEGO train wheel to run on DUPLO tracks: (fits only on MOC's, due to its size): LEGO train on DUPLO tracks - realistic steam locomotive wheel by phildc - Thingiverse

Technical remark: These wheels will only fit MOC's, as the external diameter is 32 mm, compared to the standard 24mm of LEGO and approx 28mm of DUPLO.

Additional LEGO Technic wheels that run on DUPLO tracks: Additional wheels for LEGO trains on DUPLO tracks by phildc - Thingiverse

Thanks for the info. Was not aware of this "coding-express-45025". Just found the marketing info, is there any technical info?

Awaiting other reactions, because external diameter of these wheels is 32 mm, compared to the standard 24mm of LEGO and approx 28mm of DUPLO. I have no genuine LEGO train, so I dont know how standard trains will fit with these wheels. Custom creations will be possible, anyway. It is a "work in progress". To be continued ...

Yes, we were disappointed by the completely limited number of locomotives and cars in DUPLO (influence of my grandchildren :) ). Now, we can design any in LEGO bricks, and with all the power of Technic Powered Up hub motors and sensors, if desired (there you feel the influence of the grandfather :) ). Start building ! (if necessary, open a new topic, and make a link from here)

Train wheels to run LEGO build trains on DUPLO train tracks. I just designed the following prototypes to print in 3D: (the STL files are free) LEGO trains on DUPLO tracks by phildc - Thingiverse Additional wheels for LEGO trains on DUPLO tracks by phildc - Thingiverse

Just designed 3D printable train wheels. The goal is to run LEGO build trains on DUPLO train tracks. The STL files are free: LEGO trains on DUPLO tracks by phildc - Thingiverse Additional wheels for LEGO trains on DUPLO tracks by phildc - Thingiverse

Avilable as STL files at: Additional wheels for LEGO trains on DUPLO tracks by phildc - Thingiverse

FYI, I designed LEGO Technic wheels to print in 3D, that would fit on DUPLO tracks. This opens the possibility to build new locomotives and cars for the DUPLO train. A first prototype is available as STL file. Additional models are in design. Ref: [WIP] Duplo Technic Train - Page 2 - LEGO Technic, Mindstorms, Model Team and Scale Modeling - Eurobricks Forums

A first prototype wheel is available on Thingiverse: LEGO trains on DUPLO tracks by phildc - Thingiverse Other models are in preparation:

I am currently designing a wheel that will fit on a LEGO-build locomotive, to run on DUPLO tracks. Phil.

Just discovered this great book! Thanks a lot! Phil.

A more complete view of the sensors integrated in the Powered Up Hub (position, accelerometers): The Powered Up Android app is used. To test the reaction of the hub to position and movements and check the values, just paste the icons on the screen, but do NOT start the program. The position value is set to zero at start-up. The angular values are in degrees. The acceleration values ?? did not find a G value for the Z axis, e.g. Phil.
