The Société des Chemins de fer Katanga-Dilolo-Léopoldville (KDL) was a railway concession owner in the Congo Free State, Belgian Congo. The network was built, maintained and operated by the Compagnie du chemin de fer du bas-Congo au Katanga (BCK).

In 1952 the Société des Chemins de fer Léopoldville-Katanga-Dilolo (LKD) merged with Compagnie de Chemin de fer du Katanga CFK to form the Société des Chemins de fer Katanga-Dilolo-Léopoldville (KDL).^[1] The merger of the two companies was the work of Odon Jadot, chairman of the board of both CFK and KDL. The new company was the sole railway concessionary in the Katanga Province.^[2] KDL held the rail network concessions in Katanga, while BCK was the operator.^[1]

In 1960 the company was nationalized and became the Compagnie des Chemins de Fer Kinshasa-Dilolo-Lubumbashi (KDL). In 1970 the company took over BCK.^{[citation needed]} On 1 July 1974 the Compagnie de chemin de fer de Kinshasa-Dilolo-Lubumbashi was taken over by the state-owned Société Nationale des Chemins de Fer Zaïrois, which now owned all the railways in the Congo.^[3][4]
