The complete overhaul and philological restoration of the historic car n. 6, originally built in 1902 and considered as the oldest functioning carriage around Europe and one of the oldest of the world, obtained considerable interest amongst sector experts and newspapers.


Quaiat, the restoration contractor, took care of the
carpentry and mechanics.The chassis was completely overhauled and the damaged parts were replaced, the conjunctions between parts were restored using hot riveting as a hundred years ago, when the electric welding between metals had not yet been invented.
The original rims and axles were tested and regenerated. Same procedure was applied to the leaf suspension of the frame. The transmission gears were also kept original: they are composed by two half gears, joint by screws. After being built with the tool machine, the axel bushings are covered in the contact area by wear-proof fused white metal.
