It is home to the Christanna Campus of Southside Virginia Community College. For much of the 20th century, Alberta marked the junction of two railroad mainlines. The Richmond, Petersburg and Carolina Railroad from Petersburg, Virginia to Ridgeway Junction was completed in 1900, at which point it was merged into the Seaboard Air Line. By 1914, the population of Alberta was estimate by the railroad to be somewhere around 100. The Seaboard line continued to operate into the 1980s, and today Alberta is along the abandoned portion of the CSX Norlina Subdivision. The Virginian Railway opened in 1907 from Norfolk to Victoria, Virginia, passing through Alberta. The Virginian continued in use until it was gradually abandoned following a merger with Norfolk and Western in the later half of the 20th century.
