According to the 1890 US Census, Houston was home to 210 manufacturers hiring over 3,000 employees, about 300 of whom were white-collar workers. These companies included metal working facilities, such as blacksmith shops, iron foundries, and wheelwrights; woodworkers, such as cabinet makers and millworks; and many publishers and printers. Over 1,100 workers were employed by Houston railroads, many of them at the large shops of the Southern Pacific Railroad, the Houston and Texas Central Railroad, and the Houston, East and West Texas Railway. Three years later, there were ten railroads doing business in Houston.
