Car only survivor of the “Paris-Rome” clockwork train with “presidential” type locomotive with so-called automatic running. See the Paris-Rome set box with flying junction on the Les Trains Jouef website by Philippe Galaup.
The loco died by breaking its motor spring. The successor of this clockwork Paris-Rome was the… electric Sud-Express — the word electric is to read with stars in the eyes!
