For 63 years, from 1909 to 1972, the Marianna and Blountstown Railroad was Calhoun County's link to the railroads and commerce of the nation. Sometimes known as "Many Bumps" or "Meat and Bread," the M&B had a significant impact on the lives of Calhoun Countians. Until 1929, before automobile travel was commonplace, it provided passenger service. Farmers used the railroad to ship a wide array of agricultural products. In the early years, logging spur lines extended into remote areas of the county, and millions of board feet of long-leaf pine lumber were shipped from local sawmills. The line also carried mail, manufactured goods, and building products. During its operation, the 29-mile-long line was Florida's shortest railroad. Until 1938 it ran 16 miles farther south to Scotts Ferry. Steam locomotive number 444 was in operation when the M&B's first diesel engine arrived in 1947 and rests today on the exact location of the M&B roadbed.
