Charleston & Hamburg Railroad Officially known as the South Carolina Railroad, the line from Charleston to Hamburg, South Carolina, across the Savannah River from Augusta, was the longest railroad in the world (136 miles) when completed in 1833. Although intended to connect Charleston and Memphis, the railroad progressed no farther west than Hamburg. The Memphis connection was eventually made, however, by the construction of the Georgia Railroad, the Western and Atlantic, and the Memphis and Charleston. The lines were joined in 1858.
