And... are there any materials about magnet drive for train?

But how are they held in position?

But... How are radiators made? And the same about wheels.

No. I think this can be used for holding the scene together.

Basic R40 track + TrixBrix "R40+1/2" for narrow gauge. Maybe, later I'll print my own track.

And what about this?

One example: It is driven using a belt + that yellow parts.

Could someone help me to create motorized bogie for this track? It is for the steam engine, so valve gear is also needed. Loco formula would be 0-4-0 (or 0-4-2, but I will add back bogie later). Maximum width of the train is 5 studs. I can use only https://www.bricklink.com/v2/catalog/catalogitem.page?P=55423c01#T=A as wheels for this bogie.

I'm working on a minimum gauge loco (3-stud gauge). Demo rails can be seen on the image. I need a bogie for a steam engine (0-4-0). It is limited in width: only 5 studs (with valve gear). And it must be motorised. I can use only https://www.bricklink.com/v2/catalog/catalogitem.page?P=55423c01#T=A as wheels for this train.
