Tolar Grande is a village and rural municipality in Salta Province in northwestern Argentina.

This notable increase was due to policies promoted by local authorities with the aim of reversing the emigration process and the consequent depopulation.

It is estimated that at that time, around 5000 people lived in the town, mainly dedicated to railway activity.

At the same time, during this period the La Casualidad Mine was in full activity, transporting the sulfur cargoes from Mina Julia to the Tolar Grande railway station, to be shipped from there to their final destination.
