At its peak during the golden years of the Buenos Aires tramways, the company employed around 2,000 people and was involved in diverse areas of manufacturing outside the production of rolling stock.

[1][2] The company supplied trams and other vehicles to the city of Buenos Aires.

However, the company also sold trams to the city of Asunción in Paraguay where they remained in service for many years.

[4] The Tram was produced from 1942, however it was only in service for around 10 years since fierce competition from bus travel in Buenos Aires meant that there was less demand for high capacity trams of this kind.

During its time in service, it was limited to lines that ran near the centre of the city since its great height meant that it was unsuitable for safe clearance under certain bridges, tunnels and underpasses.
