Messrs. Atilio Brunelli and Severino Porchietto traveled by car from Balnearia to the city of Cordoba, when they observed on the left side of the road, about 150' from the route and on a completely flat land, a row of rectangular lights that they attributed to a railway convoy stopped.
The lights, of soft orange coloring, seemed to correspond to a structure of about 150' long. Although the railroad track runs 30' from the road, parallel to it, in a later check, it was noticed that the windows of the conventional convoys were square, smaller and with a white luminosity that allowed to see without difficulty the interior of the wagons.
