In celebration of National Train Day, the city of Denmark hosted a reception at the historic Denmark Train Depot.

In Jan, 2004, The city of Denmark awarded contracts to restore the depot and to transform it into a visitors' center and a multi-use building along South Carolina's Heritage Corridor.

The location of Denmark had an enormous influence upon its early development. The first railroad which ran from Charleston to Hamburg was built form 1830-1833. This railway ran through Captain Z. G. Graham's Turnout. When a new railroad running from Columbia to Savannah crossed Graham's, the town continued to grow. The beginning of railroads was an extremely important factor in the origin of Denmark. The early name of Denmark changed from Graham's Turnout to Graham's. When a different railroad crossed the original in 1893, a new town was formed. The older section of town was referred to as East Denmark, and the new area was called West Denmark.

The former railroad line through Denmark was one of the longest train lines in the country at the time it was built, serving passengers and commerce. It was especially beneficial to distribution of agriculture products. With the completion of a stretch of the Manchester and Augusta Railroad near the town, it became a railroad junction of some importance."

On May 10, 1869, in Promontory Summit, Utah, the “golden spike” was driven into the final tie that joined 1,776 miles of the Central Pacific and Union Pacific railways, ceremonially creating the nation’s first transcontinental railroad.
