Jouef 843 E
This locomotive was recently offered to me by a friend. Good condition, apart from the seriously faded paint and ventilation grid broken in two places. Buffers intact. The motor is weak.
This model has four driving axles, with a driving shaft that connects the two bogies. The motor is below, in the transformer box. On the other hand, there is no traction tyre.
The central axles of each bogie are fixed, and the wheel flange and rim are ground so as not to touch the rails!
No box, no lighting.
