The construction of a railroad line from Mineola, Texas, in 1872 stimulated growth in the city. Settlers were drawn by tales of the healing powers of the city's sulphur baths. Due to population growth, the springs of sulphur were gradually covered. None is active today. A rail line was run from Jefferson to Sulphur Springs in 1879. The St. Louis, Arkansas & Texas Railroad (Cotton Belt) was built through Sulphur Springs in 1887 on its way to Commerce and Sherman. The next year, the line was completed to Fort Worth, connecting the city to a major market. In 1891, the bankrupt railroad was sold to Jay Gould interests and renamed the St. Louis Southwestern Railway.
