The Société des Chemins de fer Léopoldville-Katanga-Dilolo (LKD) was a railway concession owner in the Congo Free State, Belgian Congo.

The Société des Chemins de fer Léopoldville-Katanga-Dilolo (LKD) was created through a 16 September 1927 agreement between the government and BCK, and was an administrative and financial vehicle.

The government was its main shareholder, and granted it concessions for the three lines: Bukama–Port-Francqui, Tenke–Dilolo and Port-Francqui–Léopoldville.

At Dilolo the BCK network connected to the Benguela railway, which carried goods to the port of Lobito on the Atlantic.

KDL held the rail network concessions in Katanga, while BCK was the operator.
