hroughout its active life, Madrid-Delicias Station was the workplace for thousands of railway workers, whose professional life took place within its walls.

At the end of the Spanish Civil War, there were around 1,100 workers in Madrid-Delicias Station, with women accounting for barely fifty. Madrid-Delicias featured personnel from all the different services, the most numerous being that of Material and Traction (with three hundred employees), followed by the Operation Service, which was in charge of regulating and controlling railway traffic (with two hundred and eighty). The third most numerous group was auditing (with one hundred and forty-seven), followed by track and facility maintenance (with one hundred and seventeen employees).
