 Advertisements were taken out in the local Memphis paper in 1886, asking for men who would be paid $1.75 per day, to be depot switchmen.Not only was the railroad a result of the economic growth, it led to further expansion in the second half of the nineteenth century as industrial firms moved into Memphis to take advantage the city's central geographic location and railroad system which helped make Memphis a major hub for distribution in the south.The city underwent a major population growth as well, having less than 1,800 citizens in 1840, to 20,000 in 1858.
