Context paragraphs:
South Carolina Canal and Railroad Company: The South Carolina Canal and Rail Road Company was chartered under act of the South Carolina General Assembly of December 19, 1827.  The company operated its first 6 mi line west from Charleston, South Carolina in 1830.  The railroad ran scheduled steam service over its 136 mi line from Charleston, South Carolina, to Hamburg, South Carolina, beginning in 1833.  Some sources referred to the railroad informally as the "Charleston and Hamburg Railroad", a reference to its end points, but that was never its legal name.  In 1839, The Louisville, Cincinnati and Charleston Railroad Company, which had built no track of its own, gained stock control of The South Carolina Canal and Rail Road Company, which continued to operate under that name.  In 1844, The South Carolina Canal and Rail Road Company merged with The Louisville, Cincinnati and Charleston Railroad Company.  The merged company changed its name to South Carolina Railroad Company under an act of the South Carolina legislature dated December 19, 1843.
